Cautions while determining the workpiece clamping?

The following three points should be paid attention to when determining the positioning reference and clamping plan:

1. Strive to unify the design, technology, and programming calculation benchmarks.

2. Minimize the number of clamping times, as far as possible to be able to CNC process all the surfaces to be processed after one positioning.

3. Avoid using manual adjustment schemes.

4. The fixture should be opened smoothly, and its positioning and clamping mechanism should not affect the tool movement in cnc processing (such as collision). In such a situation, use a vise or add a base plate to draw a screw.
