Difficulty: Easy
Choose an option
-
ATrue — it can be fed in either direction
-
BFalse — it must be fed only left to right
-
CFalse — it must be fed only right to left
-
DOnly for taper turning it can go both ways
Answer
Correct Answer: True — it can be fed in either direction
Explanation
ConceptA round-nose tool has a symmetric profile about its nose radius, so for straight turning/finishing it can be used with feed in either direction provided the tool geometry (rakes/clearances) and setup are appropriate.
Practical noteEnsure adequate clearance and chip evacuation in the chosen direction; otherwise surface finish may be affected.
Final AnswerTrue — either left→right or right→left is acceptable.
