rapid change to, in other words when the NC machine tools must cease immediately, or Jiangsu, and then implement the next step. As the machine tool acceleration restrictions, easy to cause a waste of time, and exigency stop or radical move would damage the surface accuracy. In the mold of high-speed finishing, in each Cut, cut to the workpiece, the feed should try to change the direction of a curve or arc adapter, avoid a straight line adapter to maintain the smooth process of cutting.
3 Die in high-speed milling processing of
Milling as a highly efficient high-speed cutting of the new method,in
Mould Manufacturing has been widely used. Forging links in the regular production model, with EDM cavity to be 12 ~ 15 h, electrodes produced 2 h. Milling after the switch to high-speed, high-speed milling cutter on the hardness of HRC 6 0 hardened tool steel processing. The forging die processing only 3 h20min, improve work efficiency four to five times the processing surface roughness of Ra0.5 ~ 0.6m, fully in line with quality requirements.
High-speed cutting technology is cutting technology one of the major developments, mainly used in automobile industry and die industry, particularly in the processing complex surface, the workpiece itself or knives rigid requirements of the higher processing areas, is a range of advanced processing technology The integration, high efficiency and high quality for the people respected. It not only involves high-speed processing technology, but also including high-speed processing machine tools, numerical control system, high-speed cutting tools and CAD / CAM technology. Die-processing technology has been developed in the mold of the manufacturing sector in general, and in my application and the application of the standards have yet to be improved, because of its traditional processing with unparalleled advantages, the future will continue to be an inevitable development of processing technology Direction.
高速切削加工是一种先进制造技术，不同于传统加工方式。它的主轴转速高、切削进给速度高、切削量小，单位时间内的材料切除量却增加3～6 倍。它以高效率、高精度和高表面质量为基本特征，在汽车工业、航空航天、模具制造和仪器仪表等行业中获得了广泛的应用，取得了重大的经济效益，是当代先进制造技术的重要应用。长期以来，人们对模具的加工一直采用铣削一磨削或者电火花(EDM)加工、打磨、抛光的方法。虽然电火花可加工硬度很高的工件，但较低的生产率使它的应用受到制。随着高速加工技术的发展，采用高速切削取代磨削抛光和电加工进行模具加工已成为可能。
使加工周期大为缩短，加工质量得到可靠保证，加工成本降低。
