下面介绍的是沈阳第一机床厂齿轮制造的金工操作卡片实例。加工后成品图及其技术要求如图1所示;加工前毛坯如图2所示。 这一接合器齿轮在未制订工艺规程以前,车工方面系以四个操作加工。即粗、精车两端各分两次进行,全部车工实际工时为2小时18分。 但在制订工艺 规程时,经施工 The following is an example of the metalworking operation card made by Shenyang No.1 Machine Tool Plant. After processing the finished figure and its technical requirements shown in Figure 1; pre-processing rough shown in Figure 2. The clutch gear in the absence of the formulation of the process before the turndown of the Department of the Department of four operations. That is rough, fine car at both ends of the sub-two times, all the car working hours for 2 hours and 18 minutes. However, in the development of process procedures, the construction
