Question

The relative motion between the cutting edge of the tool and the work is called ______.
1. cutting speed
2. cutting ability
3. rotating speed
4. feed motion

Answer 1

Correct Answer - Option 1 : cutting speed

Explanation:

Machining:

• These are the processes which are far more difficult to model physically than metal forming processes. This is because of the distinct behaviour of the machining processes.
• In almost all machining processes, a wedge-shaped tool or a number of tools make. contact with the workpiece and remove the material in the form of chips. The process of chip formation is not known properly.
• There are a number of machining processes but in all of them, there is a relative motion between the tool and workpiece, which is called cutting speed.
• In addition to the main cutting motion, the tool is traversed perpendicular to the cutting motion, which is called feed motion If the cutting edge is perpendicular to the cutting velocity. The process is called orthogonal cutting.
• If the cutting edge is not perpendicular to the cutting velocity, the process is called oblique cutting. Most machining processes are oblique cutting processes. However, because of their simplicity, orthogonal machining processes have been studied a lot and findings have been extended to oblique cutting
