如何选择数控刀具(国外英文资料) First, the scientific choice of CNC cutting tools 1, select the principle of CNC cutting tools Tool life is closely related to cutting parameters. The reasonable tool life should be chosen first when the cutting amount is worked out, and the reasonable tool life should be determined according to the optimization target. Generally the highest productivity, the tool life and the lowest cost, tool life two kinds, the former according to a single work time minimum goal is determined, the latter according to the process cost minimum goal is determined. When choosing the tool life, consider the following points, depending on the complexity of the tool, the cost of manufacture and the cost of sharpening. Complex and high precision tool life should be higher than the single point tool. For machine tool with indexable inserts, because of the short time of changing tools, in order to give full play to its cutting performance and improve production efficiency, the tool life can be reduced a little, and generally take 15-30min. The knife, knife and knife adjustment for complex multi cutter machine, combination machine tools and automatic processing tools, tool life should be higher, you should ensure that the tool reliability. A process in the workshop productivity limits the improvement of productivity in the workplace, the operation tool life to choose some lower when one process per unit of time sharing to expenditure on plant M is large, the tool life should choose some lower. In case of heavy finishing, the tool life shall be determined according to the parts accuracy and surface roughness in order to ensure that at least once the cutter is removed and the tool is changed halfway. Compared with ordinary machining, CNC machining has put forward higher requirements for the tool, not only because it is good, high precision, and dimensional stability, high durability, and broken exhaust performance requirements at the same time it convenient installation and
