在工具和模具的凹腔加工中,所采用的加工方法有压制阴模法、仿形加工、电火花加工、超声波加工和数控加工。每一种加工技术各有其自己的局限性。数控加工模具的主要困难在于程序的编制,特别是非数学外形的程序编制。 美国辛辛那提米拉克隆公司研制了一种扫描装置。这种装置就是一种通用的仿形器指销。将仿形器指销在模型或预先加工好的零件上手工移动,就可以编制出任意复杂形状的数控程序。 在扫描操作中所产生的尺寸数据输出被输送到CIP/2100微型计算机。微型计算机
In the processing of tools and mold cavity, the processing methods used are pressing the negative mold, profiling, EDM, ultrasonic machining and CNC machining. Each processing technique has its own limitations. The main difficulty of CNC machining mold lies in the programming of the program, especially the programming of non-mathematical appearance. The United States Cincinnati Milacron has developed a scanning device. This device is a generic profiler pin. By copying the profiler finger on the model or pre-machined part, you can program a CNC program of any complexity. The resulting size data output during the scan operation is delivered to the CIP / 2100 microcomputer. Microcomputer
