Correct option is D
A
compound rest is also referred to as a
tool rest in a lathe machine. It is used to hold the cutting tool and provides a means for precise angular adjustment of the tool for operations like taper turning and fine cuts. The compound rest is mounted on the cross slide and can be rotated to any desired angle for specific machining operations.
Compound Rest Function:
· Provides angular movement of the tool for taper turning and chamfering.
· Holds the tool post securely and allows fine adjustment during precision operations.
Components of the Compound Rest:
Swivel base: Allows the compound rest to rotate to a specific angle.
Slide: Provides linear movement of the cutting tool in the desired direction.
Difference from Cross Slide:
Cross slide provides linear motion perpendicular to the spindle axis.
Compound rest provides both rotational and linear motion for angular cuts.
Applications: Used in threading, taper turning, and small angular adjustments.
