Sanding of the workpiece is to be done on the upward side of the rotation of the disc.TRUEFALSE

Analysis of the Statement

The statement that "Sanding of the workpiece is to be done on the upward side of the rotation of the disc" is related to the operation of disk sanders and the principles of woodworking machinery.

1. Understanding the Operation: Sanding is a process that involves using an abrasive material to smooth surfaces. The direction in which the abrasive contacts the material significantly affects the quality of the finish.

2. Contact Point: When a disc sander rotates, one side moves toward the workpiece (the downward side) and the other side moves away from it (the upward side). It is generally more effective to apply the workpiece to the downward side because that is where the disc is pulling the workpiece against itself, allowing for better control and a smoother finish.

3. Implications: If sanding is done on the upward side, it may lead to less effective material removal and could even cause the workpiece to be lifted or moved away due to the rotation, leading to a poor sanding outcome.

Conclusion

Given the principles of how disk sanders operate effectively and the mechanics of sanding:

Final Answer: FALSE. Sanding of the workpiece should be done on the downward side of the rotation of the disc for optimal results.
