What are the advantages of using carbide cutting tools on a lathe?

• Carbide cutting tools offer higher hardness, wear resistance, and thermal conductivity compared to other cutting tool materials. They also provide better surface finish and longer tool life.

• Carbide cutting tools have lower thermal conductivity compared to other cutting tool materials.

• Carbide cutting tools provide a worse surface finish and shorter tool life.

• Carbide cutting tools offer lower hardness and wear resistance compared to other cutting tool materials.

What is the role of the rake angle on a lathe cutting tool?

• It helps to control the cutting action and chip formation.

• It has no effect on the cutting process.

• It determines the color of the finished product.

• It helps to keep the lathe clean.

Explain the concept of cutting speed in relation to lathe cutting tools.

• Cutting speed is the number of teeth on the cutting tool.

• Cutting speed is the temperature at which the cutting tool operates.

• Cutting speed is the speed at which the cutting tool moves across the workpiece.

• Cutting speed is the amount of pressure applied by the cutting tool.

What safety precautions should be taken when using lathe cutting tools?

• Wearing loose clothing and not paying attention to the workpiece

• Using the lathe cutting tools without proper training and supervision

• Not wearing any protective equipment and leaving the workpiece unsecured
