Thus, you can obtain premium components without spending money on specialist tools or expertise.

What Challenges Faced in CNC Machining Outsourcing?

Outsourcing CNC machining may provide numerous advantages, but it comes with its own downsides. From losing partial control over the process to increased logistics and shipping costs, here are the challenges of CNC machining outsourcing:

Quality and Consistency Considerations

When you outsource a task, you may have less control over the quality of the output. While this can be mitigated by choosing a reliable CNC shop with comprehensive machining capabilities, it can be a worrisome challenge when considering outsourcing.

Variations in quality as well as consistency in getting top-notch output may hamper market flow and customer reviews. This, however, can be solved by establishing a watertight agreement with CNC expert partners for an assurance of quality and consistency.

Little Control Over Output

Every manufacturing company loves to have a certain level of control over their products, from assembly to parts fabrication. However, CNC outsourcing takes this control away to an extent as they entrust CNC machining to another firm. This factor may lead to disagreements on terms if not properly negotiated.

However, reaching a good agreement with a reliable company and providing clear requirements will help reduce the risk of getting unsatisfactory results from outsourcing.

Challenges in Communication

As stated above, clear requirements are necessary when outsourcing a task and delegation in general. The success of CNC machining outsourcing relies greatly on the clarity of communication between both companies.

However, discrepancies in communication due to language barriers or other factors may affect the efficiency of the entire process, leading to low-quality output. You can avoid this by establishing a clear mode of communication from the onset.

Increase in Logistics Cost

While CNC machining outsourcing can save you the cost of setting up and running expensive machinery, it comes with logistics costs. If you outsource to a company that is far from your production facility, it may incur more costs for transporting CNC machining materials to the partner. Partnering with a company nearby can help mitigate this challenge.

How to Choose the Right Partner for Outsourced CNC Machining Services?

When employing the concept of outsourcing CNC machining, you have to develop a good method of reducing the challenges and maximizing the benefits. One of the ways to achieve this is by choosing the right partner for your outsourcing. Several factors should be considered when choosing your partner:

Good Reviews and Track Record

What is First Article Inspection?

Let us start by establishing a definition of 1st article inspection. First Article Inspection (also abbreviated as FAI) is a fundamental process in manufacturing production that helps ensure everything is up to the mark before full-scale production begins.

It involves a series of initial checks and documentation of the first item produced in a new manufacturing run to verify the viability and performance of the manufacturing setup. It is also common to implement an FAI process on existing products after major changes in their engineering design.

1st article inspection is a common process in high-precision industries with a lot of costs associated with production failures. For example, the aviation, defense, and automotive industries follow established quality control and inspection standards in their FAI process. Some of the well-recognized standards include SAE AS9102, EN9102, and ISO 9001.

Why is the FAI Important in Manufacturing?

Now that we have an understanding of the FAI meaning, let us dive a bit deeper and see how the FAI process is significant for manufacturers.

Confidence in Manufacturing Processes

The core purpose of 1st article inspection is to validate the manufacturing process in the production line. Generally, any errors or issues are identified during the FAI process, reducing the investors’ risk by minimizing cost, time wastage, and possibly even product callbacks in the future.

For example, suppose a part is to be made with CNC machining, and the CAM program developed by the production team accidentally adds an extra tool offset in one of their operations. This will show up during part inspection in the FAI process as a dimensional error, helping the team identify the root cause and fix it.

Ensure Product Quality

In a manufacturing environment, most quality checks are generally performed at the end of a production run. Thus, any quality issues are identified at a point where not much can be done about them. This is a high-risk situation for parts like airplane wing trusses or medical instruments.

Another reason to implement 1st article inspection is to perform an in-depth quality check for the first manufactured article and pinpoint any quality problems before they appear in a mass-produced batch. This gives the production team the confidence to go ahead with mass production.

Compliance with Industry Standards

As mentioned above, there are several industry standards for first article inspection that companies follow. By meeting the FAI requirements and preparing a professional FAI report, manufacturers show their compliance with these standards.

Improved Customer Satisfaction

Enhancing customer relationships is another purpose of 1st article inspection. Many businesses offer custom manufacturing services to their customers. By providing customers with a first article inspection report before beginning a batch, the manufacturer conveys their professionalism and dedication to customer satisfaction, which is always a good way to strengthen customer relationships.

Tools Used for FAI Process

1st article inspection can comprise a full-scale product inspection consisting of dimensional checks and mechanical testing, among other quality checks. In this section, we will discuss some of the common first article inspection equipment and procedures.

Hand Measuring Tools

The first and foremost quality check in an FAI process is dimensional. A quality expert checks all the part dimensions and tolerances with the reference values to the engineering drawing.

The most common way to perform these checks is through hand-measuring tools like calipers, micrometers, dial gauges, and surface plates. The quality professional may use analog or digital tools, depending on the first article inspection requirement.

Coordinate Measuring Machine

A coordinate measuring machine (CMM) is quite useful for performing dimensional and form verifications for high-precision parts. A CMM has higher measurement accuracy than hand tools and can measure hard-to-check features like internal crevices and curves. Therefore, a CMM is quite helpful where manual tools are ineffective.

Additionally, a CMM can also generate detailed reports to share inspection results with the production team and customers.

Mechanical Testing

For certain products, mechanical properties are also important to check apart from dimensions. The most common check in this regard is material verification. Engineers use tools like spectrometers and hardness testers to check whether the material is up-to-the-mark or not.

Moreover, other mechanical testing for attributes like surface roughness, electrical properties, and cracks are also common in FAI procedures.

Software

1st article inspection is a detailed process with a significant amount of documentation. Manufacturers prefer to use professional software to handle these first article inspection requirements in a time-efficient and professional manner.

These software are generally integrated with the proprietary software being used in the company. For example, they may read quality inspection data directly from digital instruments like CMM, cameras, or RFID scanners, saving a lot of time and minimizing human error.

Main Documents in FAI Report

The First Article Inspection Report (FAIR) is a document that records the procedure and result of each activity in the FAI process. It is a comprehensive overview of the quality of the article, offering readers a quick way to analyze the performance of the manufacturing process.

Manufacturers follow various guidelines and conventions for generating FAI reports. Therefore, it is not easy to pinpoint an exact format. Therefore, in this section, we will comprehensively highlight some of the main documents in the first article inspection report as per the AS9102 standard.

Form 1: Part Number Accountability

This is an introductory form that documents the part being inspected, including its unique identification, revision number, and any of its sub-assemblies.
It brings the reader up to date with the specific product/sub-assembly this FAI is referring to and what they should expect in subsequent forms.

Form 2: Product Accountability

This form documents details about the raw materials, production-related processes, and any functional tests associated with manufacturing the part. It helps ensure that the correct material and appropriate processes (heat treatment, surface treatments, etc.) are used in the process.

Furthermore, it also contains information about functional tests performed on the article. These tests can be for material characteristics or performance. Form 2 explains the procedural details as well as the testing environment.

Form 3: Characteristic Accountability

Form 3 mainly records the results of dimensional inspections. It includes information on how well the features of the part conform to their set dimensions, tolerances, and form tolerances.

This information helps manufacturing engineers gauge the success and flaws of operations like CNC machining, grinding, additive manufacturing, etc.

Balloon Drawing

A balloon drawing, or a bubble drawing, is like an appendix in the first article inspection report. It consists of the part’s technical drawing with a ‘bubble/balloon’ placed at points of interest in an FAI process. For example, if a certain surface needs to have a specific roughness value, that surface may be identified with a balloon.

Balloon drawings simplify the inspection process, facilitate communication between team members, and ensure completeness of the 1st article inspection process.

First Article Inspection Process

The FAI process is very systematic in nature. A well-planned 1st article inspection can have several steps for smooth and effective execution. A brief overview of its common steps is as follows:

1. Planning

In the beginning, engineers make some core decisions to define the first article inspection requirements. They define which industrial standards to follow, what processes to include, and draft balloon drawings to serve as benchmarks.

2. First Article Production

After planning, the production line manufactures the first article in question. This process is in collaboration with the production team. The article may be the very first or an article from a particular batch.

3. Inspection

The next step is the actual inspection. Experts utilize first article inspection equipment to verify part dimensions, material properties, and other characteristics defined during the planning phase.

4. Documentation

After the inspection processes are finished, the next step is to draft the first article inspection report. It contains all the necessary details of the FAI process procedures, results, and reference information.

5. Review and Approval

The final step is to review the report. This is, of course, the responsibility of a senior team member, who performs a detailed check of all activities and approves the report if satisfactory. With this, the first article is either approved or rejected for further production, and the report is ready for sharing with the customers.

When Should First Article Inspection be Used?

1st article inspection has multiple use cases where it can be beneficial for manufacturers, customers, and other stakeholders.

Arguably, its most relevant application is when launching a new product. After designing it and preparing it for manufacturing, it is good to test the viability of the manufacturing setup through an FAI process.

There are, however, some other reasons to perform a first article inspection as well. Whenever there is a major design change that makes it to the production stage, it is prudent to re-analyze the efficiency of the manufacturing setup with FAI.

Similarly, other reasons to trigger a new FAI process can be a change in manufacturing equipment, production sites, and suppliers. All these reasons have the potential to deteriorate manufacturing quality to a point where the product may not be able to pass quality checks. 1st article inspection can be very helpful to identify flaws in time and save resources.

PPAP vs FAI: What is the Difference?

Production Part Approval Process (PPAP) is a quality control process in manufacturing that ensures that a manufacturer is capable of producing components up to a certain standard. By definition, PPAP is quite similar to 1st article inspection.

While it is true that these processes are very much alike, there are some fundamental differences that we aim to highlight in this section. A summary of the PPAP vs FAI is in the table below.

FAI PPAP Focuses on the first article of a production run. Performs consistent checks on numerous articles throughout the production run. Performs checks on the first article only but does not guarantee continual success in future production runs. Has a broad coverage of various aspects of a production line including readiness and consistency of producing results. Documentation includes FAI reports and balloon drawings. PPAP has extensive documentation including but not limited to quality results, control plans, process flow charts, and failure modes. More popular in defense and aerospace applications. Common in mass production industries like automotive.

FAQs

What are some common challenges in implementing FAI?

FAI can be challenging when several suppliers are involved, which can cause results to deviate and be unreliable. For complex parts, FAI can be time-consuming and require a lot of resources, which may not seem financially justifiable for a single part.

How can manufacturers ensure a successful FAI process?

An established, standardized approach is a must for a successful FAI process. Preferably, in compliance with known industry standards. Additionally, having personnel with clearly defined roles, calibrated equipment, and report formats also contributes to the success of an FAI process.

How is FAI related to quality management systems?

FAI is an integral part of quality management systems. It ensures that all parts meet design requirements and that the production process is capable of producing consistent quality products.

LM76 has developed a new corrosion resistant linear bearing. In space, deep under the sea, or in the harshest environments when there can be no “Plan B,” Pegasus Series 1 Linear Ball Bearings can be counted on. In some applications linear bearings will not move for days, weeks, months or even years, however, when called on to perform they must work as if they just came out of the box. LM76’s Pegasus Series 1 Linear Bearings feature Silicon Nitride (SiNi) Ceramic Balls in a shell with retainer and end caps all made from 440 Stainless Steel and then ArmorloyTM coated.

Silicon Nitride was selected for the balls because it is: 40% lighter than steel, inert to chemicals (vapors, sea water, caustic washing and sterilizing solutions), capable of higher speeds and higher loads: (RC78 hardness), FDA compliant (used in surgical instruments), and does not corrode or support electrolysis.

The shell, bearing retainer and end caps are made from 440 Stainless Steel and coated with Armoloy TDCTM (Thin Dense Chrome). Armoloy is a hard (78Rc), coating with a micro-nodular surface texture. The coating’s nodular finish reduces the amount of surface area in contact with the SiNi balls reducing friction and extending life.

Pegasus Linear Bearings are available 2 series (closed and open), and in 4 sizes (1.000, 1.250, 1.500 and 2.000-in.). Dynamic load rating for these bearings are: 1.000-in. 220 lbs, 1.250-in. 352 lbs, 1.500-in. 490 lbs, and 2.000-in. 858 lbs. Bearings are designed for zero clearance on Class L linear shafting. For maximum performance we recommend LM76 Case Hardened 440 Stainless Steel shafting with Armoloy coating.

After ten years and more than 100,000 operating hours dredging up silt, sand, rocks and stones in some of the toughest marine environments, the Thordon Composite bearing installed on the Al Mirfa’s dredge cutter head shaft has emerged unscathed.

In drydock where the NMDC-owned dredger is being upgraded, Thordon Bearings’ Dubai-based distributor, Ocean Power International, expected that even the ‘unbreakable’ might need replacing after such demanding workloads, but it didn’t. “The Composite bearing was still in perfect working condition,” said Rafid Qureshi, Managing Director, Ocean Power International Inc.

Maarten Jansen, Thordon Bearings’ Regional Manager, said: “The water-lubricated Composite bearing was installed in 2007 to the Royal IHC-built vessel, a 97m heavy duty cutter suction dredger. These dredgers operate in some very tough environments, which require a tough, durable bearing capable of withstanding the excessive wear and tear encountered during dredging operations. These vessel types place inordinately high loads on the cutter shaft bearing which, in the past, often resulted in the replacement of traditional greased bronze and rubber bearings every six to eight months. That the Thordon solution didn’t need replacing after ten years of heavy duty service is indicative of the durability and robustness of the materials we use in all our polymer bearings.”

Composite bearing wear rates in the abrasive conditions most dredgers operate are typically half that of rubber bearings, reducing maintenance downtime over the life of the vessel. But performance was not the only reason why the dredging sector has moved away from traditional bearing materials.

“With the emergence of more stringent environmental regulations in the late 1990s most dredgers are now fitted with water-lubricated cutter shaft bearings, said Jansen. “Dredgers have to operate in some very ecologically sensitive environments and owners cannot risk polluting seas and sediments with grease and oil. For dredger owners, a water-lubricated cutter shaft bearing is often a key factor in being awarded these sensitive area projects.”

The actual bearing surface is a black homogeneous material called GM2401 which is fused to a stiff, high strength polymer sleeve to provide unprecedented performance and environmental safety. They are available for a wide range of shaft diameters in both tube and stave configuration.

Upgrade work includes the installation of the latest versions of the IHC Dredge Profile Monitor and Automatic Cutter Controller along with the installation of a dredge fleet monitoring system. NMDC opted to install the most recent versions of these automation systems to ensure its vessels are fully up-to-date and to enhance the efficiency of its operations.

5 Key Differences Between Injection and Blow Molding

 

U.S. plastics is a $371 billion industry. Innovations in plastic resins and production methods have contributed to almost every major industry, from automotive to aerospace, construction to consumer goods.

Injection and blow molding are two popular plastic molding techniques. They both have different pros and cons, and each is preferable for distinct applications.

Below are five key distinctions between injection and blow molding. Keep reading to learn more about these unique processes, so you can decide which one might be right for your project or industry.

1. Manufacturing Processes

The manufacturing processes of injection and blow molding are quite distinct. Injection molding, which has been around for more than 150 years, uses high pressure to inject molten thermoplastic into a two-part mold. Once the plastic cools and solidifies, the mold is opened and the part is ejected.

Blow molding uses melted plastic as well. It is formed into a parison, which is a tube-like form with a hole in one end.

The parison is placed into the mold and air is blown into it. Air pressure expands the plastic to fit the mold’s shape.

The plastic cools and solidifies. After, the mold is removed and the process is repeated.

2. Mold Design

Injection molding uses a two-part mold cavity or core. It also can involve multiple cavities for mass production. The mold allows for making very complex and precise parts, one of the biggest injection molding benefits.

Blow molding also involves a two-part mold cavity that forms the exterior shape of the product. The design focuses on creating a uniform wall thickness. This is important for the structural integrity of very thin walls.

3. Moulding Applications

Both blow molding and injection molding are suitable for high-volume production and can use a range of plastic resins. However, the types of parts they make are distinct.

Injection molding can be used to make a variety of complex and detailed parts. These include automotive components, electronics, medical devices, and other items.

Blow molding is used to produce single-component hollow containers, such as bottles, air ducts, or fuel containers. These are impossible to produce using injection molding.

The flip side is that producing thin-walled hollow parts is the only suitable application for blow molding. It cannot be used to make intricate parts or thick-walled products.

4. Material Usage and Waste

Since injection molding is a highly controlled process, there is very little excess plastic waste. Also, materials like sprues and runners can be reused.

Blow molding can result in more material waste. That is due to trimming excess material away from the neck and bottom of finished products.

5. Cost

One major benefit of blow molding is that it is more economical than injection molding. That is because setup costs, including tooling, for injection molds are substantially higher. However, both injection and blow molding are relatively cost-effective options for large production runs.

It’s often said that there is nothing new under the sun. Perhaps we simply tell old stories in new ways. That certainly could be said of the bearing; the fundamental design elements have not changed much in the last 132 years. But the bearing industry? Well, that’s a different story and there are more than a few plot twists in that narrative. To give our readers some insight and a little straight talk about what makes the industry move, we asked Rollon Corp. managing director Rick Wood for his take on the business of bearings.

Bearing Tips: What will be the most significant advance in bearings in the next 10 years?

Wood: Over the last 10 to 20 years, bearing manufacture has moved from high-cost countries to low-cost areas. New CNC processes had to replace many of the old automatic manufacturing machines. This changed the nature of the manufacturing processes and many factories became obsolete.

The next 10 years will bring more change, and bearing manufacture may return to higher cost countries that are geographically closer to bearings’ end-use markets. Shipping bearings across the sea is costly and that ties up time and cash in the transport process. Moving from batch processes to lean manufacturing will also make a more local source more timely and efficient. Lead times for customers are dropping and 16 weeks plus shipping from far away is no longer acceptable. Flexible design requirements also demand shorter lead times. However, changes in the raw material sources and supply chain (tube steel, linear guide rail cold rolled steel, steel shafts) will impact everyone. This might be the one area (not often visible to the market) which offers the greatest disruption to the bearing supply. As the supply chain goes through the boom and bust cycles, this is where shortages and surpluses often happen behind the scenes.

• Another prediction: Intelligence embedded into the bearing will be the next big thing with predictive failure and maintenance. I could envision the use of MEMS chips on bearings to sense vibration, temperature and possibly lube life, wired back to a machine controller which is monitoring the spindles for spikes, to predict an imminent failure. Sensors for position, travel and even crash could also be useful feedback to determine failure modes.

• We will see new competitors excel in the market while older competitors are merging and failing. Producers in low-cost regions will enter the market and manufacturers from former low cost regions will consolidate, sell or exit. I also anticipate that many of the larger and more mature producers will milk their product lines for high margin, while failing to enter into newer product spaces. We always think of our industry as one with high barriers to entry because of the high capital outlay required to produce. However, more companies enter every year and are getting up to speed with reduced ramp-up time. Specialists will also appear for assembly and modification of bearings (linear and round) and handle the tasks that the larger producers don’t want to do or cannot fit into their production system.

Bearing Tips: How have bearings changed, or for that matter not changed, since you got into the industry?

Wood: Not much has changed in the overall design since Mr. Fischer invented the ball manufacturing process in 1883. However, materials and ball applications have seen many iterations. We now see the industry’s greatest advances are in quality metrics, repeatability and low production costs.

Bearing Tips: What are some of the biggest bearing messes you’ve seen in your career and what could have been done differently to prevent the issue?

Wood: I think the price fixing in Europe and Japan which has yet to be settled in the US markets. Incredible fines coupled with people actually going to jail. Here are more details on the matter:

• AG Sues Ball Makers Over Price-Fixing
• KFTC punishes bearings cartel
• CCS fines first global cartel
• Collusion in the World Bearing Association
• European, Japanese bearing makers to pay more than €953 million
• Parts manufacturers plead guilty to price fixing

Bearing Tips: What are some best practices when working with bearings?

Wood: Design well. Pick the right bearing for the job and make sure it is properly protected and lubricated. Use a decent partner for the source. The cost difference between low and high-quality suppliers is small compared with the cost of failure. Delivery failure can be just as bad as product failure in the application.

Design for Delivery. Pick a common and available design, don’t be the only one in the world who uses that bearing.
Pay attention to the loads and dynamic elements of the system. Bigger is not always better since once things start moving around, all of that moving mass works against you for life.

Pay attention to where you put in your safety factors in sizing. 25% extra load capacity doubles life. Doubled load capacity extends life by eightfold. But often this extra load capacity makes other components bigger too, which increases the system’s moving mass … which then reduces life. That’s because 25% actual-load increase cut life by half. In other words, design for the right load, and apply the safety factor at the end of the equation, not in the beginning.

Bearing Tips: What advice do you have for people just getting into the industry or approaching mid-career?

Wood: You don’t get rich with the bearing industry, but if you know your stuff, you don’t become poor either. It is a fair and decent living that lets us work with, sell to, buy from and compete against mostly good people … from distributors and customers to other manufacturers.

Another point to remember: There is no magic pill with this stuff. Many people say, “Wow, you guys really know a lot about the products and industry,” and want us to teach them. So we do a seminar or two, and tell them as much as we can, and send them away. Three to six months later they ask, “Can you teach me everything you know about this stuff?” We ask, “What did you do with the last batch of information?” The response: “Uh, it’s around here somewhere … can we do a webinar or something?”

Here is a better approach:

• Listen to someone who knows their stuff about bearings (linear or round). Ask questions, and see where there might be differences between what they say and what you learn elsewhere.
• Go find catalogs for your product and all significant competitors, and then compare them.
• Ask your customer why he used a given bearing in the application, and why not another one.
• Teach someone what you learned.
• Go back to the beginning. Do it again.
