利用微机计算气门毛坯下料长度,不仅运算速度快,准确性高、还可以省去试镦,缩短新产品开发周期和节省新产品开发费用,具有良好的经济效益。 我厂使用的计算机是MIC─—PC/XT微电脑,凡能输入BASI语言的任何计算机都可应用。 已往气门毛坯下料长度的计算实践告诉我们,只要计算出颈部回旋体体积、问题就迎刃而解了。如何计算颈部回旋体体积呢?方法如下: 1）在颈部回旋体上建立坐标系,如图1 The use of computer-calculated valve blank blanking length, not only computing speed, high accuracy, but also save the test upsetting, shorten the development cycle of new products and save new product development costs, with good economic returns. My factory uses the computer is MIC ─ -PC / XT microcomputer, any input to the BASI language can be applied to any computer. In the past, the calculation of the blanking length of the valve blanks tells us that once the volume of the neck mass has been calculated, the problem is solved. How to calculate the volume of the neck whirlpool it? The method is as follows: 1) Set up a coordinate system on the neck whirlpool, as shown in Figure 1
