Which of the following operations cannot be performed on a lathe
-
facing
-
drilling
-
thread cutting
-
slotting
D
Correct answer
Explanation
Slotting cannot be performed on a lathe - it requires a slotter machine or shaper. Lathes are designed for rotating workpieces and perform operations like facing (surfacing the end), drilling (with tailstock support), and thread cutting (using lead screw). Slotting involves linear reciprocating motion, incompatible with lathe operation.
