Auto industry parts and fixture selection should pay attention to the problem

(1) The clamping method of machining mechanical parts should reasonably choose the positioning datum and clamping scheme. When we choose our benchmarks, we should follow the two principles of "unity of benchmarks" and "coincidence of benchmarks".

(2) All surface machining as far as possible in a positioning clamping to complete, therefore, it is necessary to choose easy to workpiece each surface can be processed to the positioning mode.

(3) When determining the position of the workpiece on the workbench, the machining quality of each position, the length of the tool and the stiffness of the tool must be considered.

(4) Fixture used in machining should be selected as far as possible by general parts assembly, and can be adjusted fixture, can effectively shorten the production preparation cycle.
