First, CNC machining sequence should be arranged according to the structure of the parts and blank condition, as well as positioning clamping needs to consider, the focus is not to destroy the rigidity of the workpiece.
(1) the processing of the last process can not affect the positioning and clamping of the next process, interspersed with the general CNC machining process should also be considered comprehensively.
(2) Advance the inner shape and inner cavity processing sequence, and then carry out the shape processing process.
(3) With the same positioning, clamping method or the same knife processing process is best connected, in order to reduce the number of repeated positioning, tool change times and moving the plate times.
(4) In the same installation of multiple processes, should first arrange the process of small damage to the workpiece rigidity.
Two, the tool concentration is divided according to the tool process, with the same tool processing parts can be completed on all parts. Use the second knife and the third knife to finish the other parts they can finish. In this way, the number of tool changes can be reduced, the empty path time can be compressed, and unnecessary positioning errors can be reduced.
Three, to the processing parts of the order method for processing a lot of parts, according to the structural characteristics of the processing part into several parts, such as shape, shape, surface or plane. Generally first processing plane, positioning surface, after processing holes; Machining the simple geometry first, and then machining the complex geometry; Machining the parts with lower accuracy first, and then machining the parts with higher accuracy requirements. The above is the order of CNC machining, in accordance with these several to operate, which will make your CNC machining risk greatly reduced.
