Difficulty: Easy
Choose an option
-
ATrue — side rake primarily controls chip flow and reduces cutting forces
-
BFalse — side rake only sets clearance and has no effect on chips
-
CTrue only at very low cutting speeds
-
DFalse; chip flow is controlled solely by coolant
Answer
Correct Answer: True — side rake primarily controls chip flow and reduces cutting forces
Explanation
ConceptSide rake changes the effective shear plane and influences chip direction and thickness, improving chip evacuation, reducing cutting force, and enhancing surface finish.
NotesClearance angles prevent rubbing; rake angles influence cutting mechanics and chip formation.
Final AnswerTrue — side rake primarily controls chip flow and reduces cutting forces.
