Q10
The factor responsible for the formation of continuous chips with built up edge is
A.
Low cutting speed and large rake angle
B.
Low cutting speed and small rake angle
AnswerC.
High cutting speed and large rake angle
D.
High cutting speed and small rake angle
Answer: Option B
Solution
Answer: Option B
Solution:
-continuous chip with built up edge. a built up edge (BUE) is an accumulation of material against the rake face, that seizes to the tool tip, separating it from the chip
- Discontinuous chips are formed during machining of brittle metals while continuous chips with built up edge are formed during machining of ductile materials at low cutting speed
