When determining the positioning benchmark and clamping scheme, pay attention to the following three points:
1. Strive for design, process, and programming calculations.
2. minimize the number of fixtures as much as possible, and as much as possible after a positioning, CNC can process all the surface to be processed.
3. Avoid adopting manual adjustment schemes.
4. The fixture should be opened smoothly. The positioning and clamping mechanism cannot affect the knife (such as collision) in CNC processing. When encountering such situations, you can use tiger pliers or bottom plate to draw screws.
