Answer :
The lathe specification that directly affects tool life, machining accuracy, and workpiece surface finish is the Spindle Speed.
What is the spindle speed?
Spindle speed refers to the rotational speed of the lathe's spindle, which determines the cutting speed of the tool against the workpiece. The spindle speed directly affects tool life, machining accuracy, and workpiece surface finish in the following ways:
Tool Life: The spindle speed affects the cutting speed of the tool. Running the lathe at an optimal speed helps prolong the tool's life by reducing excessive wear and preventing overheating. An incorrect spindle speed can lead to tool dulling, chipping, or premature failure.
Machining Accuracy: The spindle speed influences the precision and accuracy of the machining process. Improper spindle speed can cause vibrations, chatter, or tool deflection, leading to dimensional inaccuracies in the workpiece.
