Analysis of the moldCNC precision machiningKey points of programming
General CNC machining usually refers to the computer digital control of precision machining, CNC machining lathes, CNC machining milling machines, CNC machining boring and milling machines.
(1) For CNC precision machining mold before programming to review work, that is, to conduct a comprehensive analysis of the mold structure, work out the processing and production plan; In case of design changes due to tooling maintenance, timely review of tooling and revision of production schedule.

(2) before programming, to consider the factors of parts, first select several processing methods and paths, and then compile the program, and then modify the program according to the CNC precision machining mode, confirm that there will be no bump knife in the process of cutting, missing processing procedures and so on; In finishing, such as the mechanical mold core, cavity and other processes, we must take into account the specific number of rough processing value, to rough processing can be milling out of all parts of the milling out, part of the milling out of the gantry milling machine to open as far as possible to the required value.

When finishing, the feed quantity and feed direction of the tool must be strictly controlled. The best result is to produce the highest quality mechanical die in the shortest time.
Finally, before finishing the program on the machine, we should use numerical control simulation software to simulate and verify the feasibility of the tool rail, so as to prevent the programming human factors from causing the crash. For high-speed machining machine tools if the conditions can be optimized with NCBRAIN software, can greatly reduce the processing efficiency, improve the tool life.
(3) The processing process and after the processing to do a good job of inspection and sorting. In the process of processing, Lifei company should always check the progress and quality of processing. Once it is found that there are too many empty knives, large workpiece allowance, wrong knives, elastic knives, tool deformation and other situations, it must be timely reported to ensure that the programming and modification work can be timely and effectively, and reduce the waste of materials; After processing to strictly check, measure the workpiece parameters and missed work, error, and then report to the superior, to ensure CNC precision machining accuracy in a reasonable range. Finally, these data should be recorded to establish a workpiece processing database, which is convenient for future inspection comparison and experience summary.
