Questions & Answers

Q: What is metal cutting and why is it important to study?

Metal cutting involves removing unwanted material from a workpiece to achieve the desired component shape. Studying metal cutting allows for the determination of cutting forces, power consumption, temperature, and tool life, which are essential in selecting the right machine tools and tool materials.

Q: What are the inputs in metal cutting?

The inputs in metal cutting include the machine tool, tool material, process parameters (such as speed and depth of cut), workpiece microstructure, and work holding devices (like jigs and fixtures).

Q: What is the difference between orthogonal cutting and oblique cutting?

In orthogonal cutting, the cutting edge of the tool is perpendicular to the cutting velocity vector, resulting in two cutting forces. In oblique cutting, the cutting edge is inclined at an angle to the cutting velocity vector, leading to three cutting forces.

Q: What are the advantages of studying metal cutting?

Studying metal cutting allows for the determination of cutting forces, power consumption, temperature, and tool life. This information helps in selecting the appropriate machine tools, tool materials, and process parameters for optimal machining.

Summary & Key Takeaways

• Metal cutting is the process of removing unwanted material from a workpiece to achieve the desired size and shape of the component.

• Studying metal cutting allows for the determination of cutting forces, power consumption, temperature, and tool life, which are crucial factors in selecting the appropriate machine tools and tool materials.

• Inputs in metal cutting include the machine tool, tool material, process parameters, workpiece microstructure, and work holding devices.
