四方车辆研究所从1983年起,在研究磨耗形踏面课题工作中,已设计计算出车轮加工仿形靠模,并利用本所研究成果——作图法与线切割库过程,计算打印出线切割靠模的3 B指令单。1983年下半年,四方所应四方机车车辆工厂的要求,为加工昆明米轨内燃机车车轮,应用作图法与线切割过程,编制成用作图法计算打印线切割车轮加工靠模的电算程序,在本所的719型电子计算机上调 Sifang Vehicle Research Institute from 1983 onwards, in the study of the work of the wear-shaped tread surface task, has been designed to calculate the wheel contouring model, and the use of the results of this study - mapping and wire cutting library process, calculate the print line cutting 3 B instruction list by model. In the second half of 1983, at the request of the Sifang locomotive and rolling stock factory, Sifang applied the drawing method and wire cutting process to process the wheels of Kunming meters rail diesel locomotive, The program, the 719 in our home computer up
