    Cutting
In summary, the conversation discusses the properties and testing of ceramic cutting tools, specifically for lathe or shaper use. The desired properties include high strength, fracture toughness, hardness, and wear resistance. The conversation also mentions that high strength alloy tools are often coated with ceramics or diamond. There are standards for cutting tools from ASME and SME, but not from ASTM. However, ASTM has a committee on Advanced Ceramics and a subcommittee on Wear and Erosion.

Hello everyone,
I have a few questions about ceramic cutting tools. What properties should a ceramic cutting tool (for lathe or shaper) must have? What tests should be performed on the material/tool? Where can I find details about those test? What are the ASTM stadard for those tests? I would be grateful if you could tell me the ASTM standard numbers also.
Thank you

Perhaps some information would be available in one's textbook.

High strength, high fracture toughness, hardness and wear resistance are desirable properties for machining tools. Basically, the material cannot deform and must retain sharpness. This is why high strength alloy (e.g. steel) cutting tools are often coated with ceramics or diamond.

ASME has a number of standards on cutting tools.

Society of Automotive Engineering (SME) may also have standards.

I don't believe ASTM has specific standards on cutting tools, but they do have a committed C28 on Advanced Ceramics and G02 on Wear and Erosion.

Nevertheless -

1. What are ceramic cutting tools?

Ceramic cutting tools are tools made from ceramic materials that are used in various industries for cutting, shaping, and machining a wide range of materials. These materials are typically made from non-metallic, inorganic compounds such as oxides, carbides, and nitrides.

2. What are the properties of ceramic cutting tools?

Ceramic cutting tools have several unique properties that make them desirable for cutting applications. These include high hardness and strength, resistance to wear and corrosion, high temperature resistance, and low thermal conductivity. They also have a low coefficient of friction, which allows for smoother cutting and less heat generation.

3. How are ceramic cutting tools tested?

There are various tests that can be performed on ceramic cutting tools to evaluate their properties and performance. Some common tests include hardness testing, wear testing, and fracture toughness testing. These tests can be conducted using specialized equipment and following standardized procedures outlined by organizations such as ASTM.

4. What are ASTM standards for ceramic cutting tools?

ASTM (American Society for Testing and Materials) has developed standards for ceramic cutting tools to ensure consistency and quality in their production and use. These standards cover areas such as material composition, mechanical properties, and testing methods. Compliance with ASTM standards is important for ensuring the performance and safety of ceramic cutting tools.

5. What industries use ceramic cutting tools?

Ceramic cutting tools are used in a variety of industries, including aerospace, automotive, medical, and electronics. They are commonly used for cutting and machining hard materials such as metals, composites, and ceramics. They are also used for precision cutting in industries that require high levels of accuracy and surface finish.
