What should be noted in the determination of the workpiece clamping method in CNC machining?

The following three points should be noted when determining the positioning reference and clamping scheme:

1. Strive to unify the benchmarks of design, process, and programming calculations.

2. Minimize the number of clamping operations and, as far as possible, machine all the surfaces to be machined after one positioning.

3. Avoid using the manual adjustment program.

4. The fixture should be opened smoothly, and its positioning and clamping mechanism can not affect the machining pass during machining (such as collision). When such a situation is encountered, it can be clamped by means of a vise or a bottom plate.
