Question 1.
What does MRR stand for?
Show hintHide hint
Think of what happens when you remove material.
Question 2.
What is surface finish measured in?
Show hintHide hint
What unit do we use to describe small dimensions?
3Question 3.
What does MRR measure in machining?
- Surface smoothness
- Speed of machining
- Volume of material removed
Show hintHide hint
Think about what happens during the machining process.
4Question 4.
True or False: Lower Ra values indicate a smoother surface.
- True
- False
Show hintHide hint
Consider how we describe smoothness.
Question 5.
Calculate the MRR when the cutting speed is 100 mm/min, feed rate is 0.25 mm/rev, and depth of cut is 2mm. Explain how changes to these parameters would affect MRR.
Show hintHide hint
Focus on how multiplication affects the output.
Question 6.
Discuss how surface conditions affect the performance of machined parts in critical industries and suggest methods to improve surface integrity.
Show hintHide hint
Think of both material properties and machining processes.
