What can occur if a workpiece lacks proper support during machining?

Enhanced machining speed
Improved surface finish
Potential damage to both the tool and the workpiece
Increased lifespan of the cutting tool

The correct answer is: Potential damage to both the tool and the workpiece

When a workpiece lacks proper support during machining, it can lead to potential damage to both the tool and the workpiece. Proper support is essential to ensure stability and accuracy during the machining process. If the workpiece is not adequately secured, it may vibrate, shift, or become misaligned, which can cause excessive forces acting on the cutting tool as well as on the workpiece itself. This situation can result in chipping, breakage, or deformation of the workpiece, and it could also lead to premature wear or damage to the cutting tool. In contrast, enhanced machining speed, improved surface finish, and increased lifespan of the cutting tool are outcomes expected under ideal working conditions with proper support. However, without that stability, the machining process can produce defects in the workpiece and damage tools, highlighting the critical importance of proper support during machining operations.
