Alumina ceramics as bulletproof materials

From the current point of view, the general development trend of armor materials is toughening, lightweight, multi-functional and high efficiency. Alumina ceramic materials are an important part of bulletproof materials. They have high hardness and wear resistance, high compressive strength and excellent ballistic properties under high stress.

     The bulletproof mechanisms of alumina ceramics and metals are very different. Metals absorb the kinetic energy of projectiles due to plastic deformation, while ceramics absorb the kinetic energy of projectiles due to their rupture. Typically, ceramic armor systems are composed of a single piece of ceramic or ceramic-metal composite covered with a layer of nylon cloth bonded with high tensile strength organic fibers.

    Under the impact of the bullet, the front side of the alumina ceramic is broken and the remaining energy is absorbed by the soft reinforcement material on the back side. The back side material must be able to support the fragments of the ceramic material and the bullet itself after the bullet impact. Of course, bulletproof ceramics require many properties, including density and porosity, hardness, fracture toughness, sound speed, mechanical strength, etc. None of these properties can have a direct and decisive relationship with the overall bulletproof performance, so the fracture mechanism is very complex. Crack formation is caused by many factors and occurs over a very short period of time.

    The porosity of alumina bulletproof ceramics should be as low as possible to increase the hardness and Young's modulus; and its hardness requirements are very high, which should be higher than the hardness of flying warheads; the speed of sound propagation in alumina ceramics represents the impact surface of the ceramics The ability to consume energy, high sound velocity also indirectly indicates that the ceramic has good densification and low closed pores.

     Existing bulletproof ceramics are mainly divided into two categories, namely monolithic ceramic structure and ceramic composite structure. Monolithic structure ceramics include oxide ceramics and non-oxide ceramics, as well as binary systems. Generally speaking, non-oxide ceramics have higher physical properties and relatively low density, which are more advantageous as ballistic protection than alumina ceramics. However, these material manufacturing methods mostly use expensive hot pressing and are not easy to be industrialized. But hot pressing can improve the mechanical properties of bulletproof ceramics.

Moreover, ceramic matrix composites have high ballistic resistance due to high mechanical properties, especially fracture toughness. After projectile impact, ceramic matrix composites have better integrity than monolithic ceramics. Therefore, alumina ceramics are very suitable as bulletproof ceramics.

What are the Main Parameters for Machining Threads?

Understanding the parameters of thread machining is crucial for ensuring the effectiveness and reliability of fastening systems in various applications.

Below, we explore the critical dimensions and material considerations that define the functionality of machined threads.

Thread Dimensions

  1. Pitch: The pitch of a thread is the distance between adjacent threads measured along the length of the fastener. It determines the thread’s slope and is crucial for matching the thread with the right nut or tapped hole.
  2. Major Diameter: This is the largest diameter of the external thread, which can be visualized as the diameter of an imaginary co-axial cylinder that touches the crest of the external thread. For internal threads, it touches the root.
  3. Minor Diameter: For external threads, the minor diameter is the diameter of an imaginary co-axial cylinder that touches the roots of the threads. For internal threads, it touches the crests.
  4. Pitch Diameter: Positioned between the major and minor diameters, the pitch diameter is where the widths of the thread ridge and the thread groove are equal.
  5. Thread Angle: This is the angle between the flanks of the thread, measured in an axial plane. This angle is vital as it affects the thread’s strength and load-bearing capacity.
  6. Lead: Lead refers to the distance a screw thread advances axially in one turn. In a single-start thread, the lead equals the pitch, but in a multi-start thread, the lead increases, allowing for quicker assembly.
  7. Depth of Thread: The thread depth is the distance between the crest and the root of a thread, measured radially.
  8. Thread Form: This term describes the geometric profile of the thread. Common forms include triangular, square, trapezoidal, and others, each serving different mechanical purposes and offering varying strengths and efficiencies.

Helix and Spiral Angles

  • Helix Angle: In a straight thread, the helix angle is defined as the angle at which the helix of the thread cuts into the cylinder. For tapered threads, it’s the angle made by the cone’s helical area.
  • Spiral Angle: This is the angle at which the helix intersects the pitch diameter relative to a plane perpendicular to the axis. The spiral angle impacts the efficiency of load distribution and the thread’s capacity to withstand load.

Additional Geometric Features

  • Crest: The crest is the top surface of the thread, which is the highest point that intersects with the cylindrical or conical surfaces.
  • Root: The bottom of the thread groove opposite the crest, which forms the foundation of the thread’s structure.
  • Flank: The flank of a thread is the straight side that connects the crest and the root. The angle and quality of the flank significantly influence the screw’s performance under tension and compression.

What are International Standards For Machining Threads?

Understanding the international standards for machining threads is crucial for ensuring consistency, compatibility, and functionality across various applications and industries worldwide.

These standards are set by several authoritative bodies, each contributing to the global manufacturing practices.

  1. American Society of Mechanical Engineers (ASME): ASME is instrumental in setting the Unified Thread Standard (UTS), which defines the standardized thread forms and series for screws and nuts in the United States.
  2. American National Standards Institute (ANSI): ANSI collaborates with ASME to endorse and promote the standards across different industries, ensuring that the thread specifications meet the requirements for safety, reliability, and efficiency.
  3. International Organization for Standardization (ISO): ISO provides a set of standards known as the ISO metric screw thread series. This series is widely adopted in Europe and internationally, promoting standardization and interchangeability across borders.

Unified Threads Standard (UTS)

The UTS is among the most widely adopted thread machining standards globally. It includes:

  • Unified Coarse (UNC): This is the most common thread form used in bulk production and general-purpose fastening applications. It features a coarser thread, which makes it less susceptible to galling and allows for quicker assembly and disassembly.
  • Unified Fine (UNF): UNF threads are finer than UNC and provide greater strength and smoother torque control. They are suitable for applications requiring higher tensile strength and precision.
  • Unified Extra Fine (UNEF): These threads are used where even finer threads are necessary, such as in applications requiring light torque but high tensile strength.

What are the Different Methods for Machining Threads?

Thread machining involves various techniques like thread cutting and milling that cater to different requirements and specifications.

Each method offers distinct advantages and involves specific machinery, making it crucial to understand their applications to select the most appropriate technique.

Thread Cutting

Thread cutting involves several steps, beginning with selecting the correct tap or die based on the thread size and pitch required.

Machines Required:

  • Tapping machines: These can range from simple hand taps and dies to more sophisticated tapping attachments and machines that ensure alignment and speed control.
  • Lathes: Often used for die cutting, where the workpiece is rotated while a fixed die cuts the threads.
  • Drill presses: Commonly used for drilling initial holes before tapping, ensuring the holes are perpendicular and accurately sized.

Thread Turning

Thread turning is recognized as one of the most efficient and cost-effective methods for producing external threads, especially on longer parts. Thread turning is typically performed on a lathe or a turning center, where the workpiece is secured and rotated while a cutting tool is fed into it in a helical path. The cutting tool is precisely controlled to match the desired thread pitch and depth, ensuring accurate and consistent threading.

Pros:

  • Efficiency: Highly efficient for producing threads on long cylindrical parts.
  • Precision: Capable of achieving high precision and uniformity in thread dimensions.
  • Flexibility: Can be adjusted to create various thread sizes and types by simply changing the tooling and settings.

Cons:

Feed Rate and Pitch Alignment: It is crucial that the feed rate of the cutting tool is synchronized with the rotational speed of the workpiece to maintain the correct thread pitch. This synchronization is key to avoiding defects and ensuring the functional integrity of the thread.

Four Feeding Methods:

  1. Radial Infeed: This common method involves feeding the tool radially towards the workpiece. It’s straightforward but can lead to issues with chip breaking and tool wear.
  2. Flank Infeed: Here, the tool moves at an angle to the workpiece, which improves chip flow and surface finish by minimizing the rubbing action against the part.
  3. Modern Flank Infeed: An enhancement of the flank infeed, this method adjusts the angle of approach to optimize chip flow and reduce wear on the trailing edge of the tool.
  4. Alternating Flank Infeed: This technique engages both flanks of the thread alternately, extending tool life and improving the finish but at the expense of slightly reduced accuracy. It is particularly beneficial for threads with large pitches or specialized profiles like ACME or Trapezoidal.

Thread Milling

Thread milling is a versatile and precise method for producing threads using a rotating multi-point cutting tool. Thread milling involves the use of a CNC machine to rotate a cutter along the axis of the workpiece, cutting the thread’s profile into the material. This method can create internal and external threads and is highly recommended for high-precision tasks in various materials, including metals and plastics.

  • Precision Grinding Wheels: Customized to match the thread profile for optimal accuracy.

Thread Crushing

Thread crushing, often overlooked, is a unique method where threads are formed by displacing and reshaping the material rather than cutting it. Thread crushing employs hardened steel dies that press against the surface of the material to mold and deform it into the thread shape. The process does not remove material but rather compresses and stretches it to form threads, which can result in stronger threads due to the cold working effect.

Pros:

  • Strength: Produces threads stronger than those cut traditionally due to work hardening.
  • Efficiency: High production rates as no material is removed during forming.
  • Cost-effective: Less tool wear compared to cutting, extending the life of tools.

How to Machine Threads?

In this section you will read more practical information on thread machining. We provide an overview of the process, alongside key design tips and considerations to enhance the quality and functionality of machined threads.

What are Key Thread Design Tips?

Designing effective threads involves considering fifteen main factors to enhance both application efficiency and manufacturability.

Below is a list of the design tips that are instrumental in optimizing thread machining:

  • End Chamfer for Internal Threads: Incorporate a chamfer at the start of internal threads to facilitate easy entry for bolts and reduce the risk of cross-threading.
  • Favoring Threads with Shorter Heights: Opt for shorter thread heights to minimize material usage and reduce machining time without compromising strength.
  • Implementing Standard Thread Measurements and Shapes: Utilize standard measurements and thread profiles to ensure compatibility with other components and streamline production processes.
  • Flat Surface at the Start of the Thread: A flat lead-in surface at the start of the thread can help prevent the tool from slipping, ensuring the threads are cut accurately and consistently.
  • Boosting Wall Thickness for Cylindrical Parts: Increase the wall thickness of cylindrical parts to provide sufficient material for thread depth, enhancing the structural integrity of the part.
  • Bevel at Ends of External Threads: Adding a bevel at the end of external threads can protect the thread during handling and assembly, preventing damage and ensuring ease of use.
  • Select Appropriate Thread Pitch: Different thread pitches like UNC (coarse), UNF (fine), and UNEF (extra fine) are used based on the application’s requirements. It is crucial to choose the right pitch to match the operational demands and material properties.
  • Consider Thread Placement: Place threads strategically to ensure they are accessible for both machining and assembly. Avoid areas that might require complex tool paths or create accessibility issues during assembly.
  • Internal Thread Depth: Ensure the internal thread depth is within the tooling capability. If the required depth exceeds the tool’s reach, consider drilling from both sides or using specialized deep-hole threading tools.
  • Machining Internal Threads: Utilize single-lip threading tools for precision. It’s essential to adjust the pilot hole diameter to match the minor diameter of the threads, ensuring the correct thread depth and fit for the bolts or screws.
  • External Threads on Turned Parts: When threading external surfaces on turned parts, ensure the thread extends smoothly along the part’s length. Use custom threading tools to maintain thread continuity and avoid any irregularities.
  • Model Threads Correctly in CAD: For efficient machining, model threads in the CAD software by focusing on the major diameter and omitting detailed thread profiles. This simplifies programming and reduces the computational load on CNC machines.
  • Using Inserts for Weaker Materials: For materials with lower tensile strength, like some plastics and soft metals, integrate threaded inserts to enhance the durability and torque handling of the threads.
  • Interactive Thread Assignment in Quoting: Utilize advanced CAD/CAM software with interactive features that allow for the easy addition of threaded features directly in the quoting process, ensuring accuracy and reducing preparation time.
  • Design External Threads with Relief: Design external threads with a relief area to prevent interference with adjacent thread shoulders, ensuring smooth assembly and operation.

What are the Main Tips for Machining Threads?

When preparing to machine threads, eleven critical steps must be considered to ensure success:

  • Preparation: Calculate Bore and Cylinder Diameter: For internal threading, it’s crucial to calculate the bore diameter accurately; similarly, for external threading, determine the cylinder diameter. Both dimensions are referred to as the minor diameter (D), calculated by the formula D = N – S, where N represents the nominal diameter and S signifies the thread pitch. This calculation ensures that the threads fit correctly with corresponding components.
  • Determine Rotary Speed for Drilling: Establishing the correct rotary speed is essential for effective drilling. This speed is calculated using the cutting speed (V) in meters per minute. Correct speeds help prevent material damage and ensure clean, precise cuts.
  • Calculate Hole Depth: Proper hole depth is critical, especially for internal threads. Use metric standard tables or specific formulas for small threads to determine the appropriate depth, ensuring that the thread does not end abruptly, which could compromise the strength and functionality of the part.
  • Use Appropriate Cutting Oil: Different materials require specific lubricants to facilitate the drilling process and extend the life of cutting tools. For instance, use cutting oil for steel, spirit for aluminum alloys, and petroleum or colza oil for chromium-nickel alloys. This consideration helps improve the cutting process and prevents material galling or welding onto the tool.
  • Remove Chips and Excess Material: After drilling, it is important to remove any remaining chips or excess material using compressed air or a soft brush. This step prevents blockages and potential damage during subsequent machining stages.
  • Proper Tool Selection: Choosing the right tool for threading is paramount. The tool should match the material and type of thread being machined to prevent tool wear and ensure dimensional accuracy.
  • Lubrication and Cooling: Proper lubrication and cooling extend the life of the cutting tool and enhance the finish of the threads. This step is crucial when working with materials that generate significant heat during machining.
  • Regular Tool Maintenance: Regularly check and maintain threading tools to ensure they are sharp and properly set. This maintenance prevents defects in thread quality and ensures consistent performance.
  • Chamfers and Countersinks: Adding chamfers at the ends of external threads and countersinks at the ends of internal threads can significantly reduce stress concentrations, which might otherwise lead to cracking or failure in service.
  • Structural Evaluation for Internal Threads: It is crucial to evaluate the structural integrity of parts with internal threads. This evaluation should consider the pressure and forces that the threads will endure during machining and in their final application. In some cases, adjustments in material or part geometry might be necessary to enhance durability.
  • Using Standard Thread Sizes and Forms: While custom thread sizes can be necessary for specific applications, using standard sizes where possible can reduce manufacturing costs and complexity. Additionally, standard thread sizes are more likely to be compatible with existing parts and tools.

How to Clean and Test Machined Threads?

  1. Cleaning: After machining, it’s crucial to clean the threads to remove any residual metal shavings or lubricants. Use a high-pressure air blast or a specialized thread cleaning brush. For deeper or finer threads, consider ultrasonic cleaning methods that can remove even microscopic debris without damaging the thread’s surface.
  2. Visual Inspection: Use magnifying tools or a microscope to inspect the threads for any irregularities, such as burrs or incomplete threads. This step helps to catch issues that can affect the fitting of the threaded part in its assembly.
  3. Go/No-Go Gauge Testing: Employ go/no-go gauges to test the precision of the threads. This tool can confirm if the threads are within the specified tolerance limits. A thread that passes this test will screw into its corresponding part smoothly without being too loose or tight.
  4. Thread Micrometer Measurement: For a more quantitative approach, use a thread micrometer that measures the pitch diameter. This measurement is critical for applications requiring high precision.
  5. Torque Testing: In applications where the threads will bear significant load, perform torque testing to ensure that the threads can handle the specified load without stripping.
  6. Rust Prevention: Finally, apply a rust inhibitor if the threads will be exposed to corrosive conditions. This step ensures longevity and reliability in harsh environments.

What are the Common Mistakes in Machining Threads?

  1. Incorrect Tool Selection: Using a tool not suited for the material or thread type can result in poor quality threads. Always match the tool material and geometry with the workpiece material and thread specifications.
  2. Improper Speed and Feed Rates: Too fast or too slow drilling can lead to thread imperfections. Adhere to the recommended speeds and feeds for the material and type of thread being machined.
  3. Insufficient Lubrication: Lack of proper lubrication can cause overheating and material galling. Use the correct lubricant for the material and application, and ensure consistent application throughout the machining process.
  4. Not Accounting for Material Spring Back: Some materials tend to deform during machining and then partially spring back. Compensate for this factor in your thread design, particularly when working with softer or more elastic materials.
  5. Overlooking End-of-Thread Chamfers: Chamfers help to ease the starting of a nut or bolt. Failing to include a chamfer can lead to cross-threading during assembly.
  6. Ignoring Thread Tolerances: Each threading application may have different tolerance requirements based on the load and precision needed. Ensure that the tolerances used are suitable for the application to prevent fitment issues.
  7. Poor Handling and Storage:<

AST: Bearings in encoders: Part III- Mounting and Preload

By Christine Berlly

Bearing preload is critical in encoder spindle designs. Preload is the application of an axial load across a pair of bearings that removes the free internal clearance (or looseness) that is present in each bearing by design.

In an encoder application, this preload forces the balls into contact with the raceways allowing for load sharing and precise rotational movement. In addition, as preload is increased, the encoder spindle assembly stiffness increases. This prevents ball skidding under acceleration (and deceleration) and improves repeatability and stability.

Higher values of preload, however, also have some undesirable effects. These include increased friction, heat, stress in the raceways and ultimately bearing life is reduced. The designer must balance the need for higher preload values with these negative consequences.

The fits – both shaft and housing – for the smaller bearings used in encoders are typically light transitional fits to clearance fits. It is very common to use adhesives to secure the bearings in place. This also allows for the use of the dead weight preload method where, during the assembly process, a weight is applied to the encoder spindle (in the vertical position) while the adhesive applied to the bearings cures.

After cure, the weight is removed. This is very easy to control and produces very consistent results. Interference fits can be problematic in bearings with thinner cross sections. Poor geometry in the mating components is easily transferred to the higher precision bearings, and, if combined with components that are at their maximum limits of size, the bearing clearance can be reduced to negative values resulting in high stress and heat in operation.

What are The Seven Quality Management Principles?

The foundation of ISO 9001:2015 lies in the Seven Quality Management Principles, which are:

  • Customer Focus: Prioritizing customer satisfaction by meeting their requirements.
  • Leadership: Establishing a unified direction and conditions in which people are engaged in achieving the quality objectives of the organization.
  • Engagement of People: Recognizing that people at all levels are the essence of an organization.
  • Process Approach: Understanding activities through a process lens enhances efficiency.
  • Improvement: Fostering an environment of continual improvement.
  • Evidence-based Decision Making: Making decisions based on the analysis of data.

What are Mandatory Documents and Records?

Under ISO 9001:2015, several documents and records are mandatory, including:

The scope of the QMS

Outlining the boundaries and applicability of the quality management system, including details of any exclusions.

Quality policy and objectives

The quality policy reflects the commitment to quality from top management, while the objectives set measurable goals aligned with this policy.

Criteria for and methods of control for operational processes

Guidelines and methods to manage and control the organization’s operational processes effectively.

Records of monitoring, measuring, analyzing, and evaluating data

These records provide evidence of the QMS’s performance and the effectiveness of quality management activities.

Evidence of competence

Records demonstrating that personnel have the necessary competence (based on education, training, or experience) to fulfill their roles.

Documented information determined by the organization as being necessary for the effectiveness of the QMS

This is a flexible requirement, acknowledging that each organization might have unique needs for documentation to support their QMS effectively.

Suggested Non-Mandatory but Beneficial Documentation

While not required, the following documents can enhance the QMS’s comprehensiveness and functionality:

  • Process maps, flowcharts, and diagrams: These visual tools can significantly improve understanding and management of the QMS processes and their interrelation.
