摘要
工艺尺寸式是一种计算平面孔系工艺尺寸的新方法。与传统的工艺尺寸链相比,避免了尺寸链图的绘制,降低了计算误差,更适合计算机辅助设计。用工艺尺寸式代替工艺尺寸链计算将对提高产品质量具有一定的意义。
The measurement-manner is a new method used to calculate the craft dimension in plane hole series. Compared with the technological dimension chain,this method has many advantages,such as more convenient to find the craft dimension without drawing and with less errors, and easy for a computer to calculate. The replacement of the craft dimension chain with the measurement-manner method has the vital significance to the improvement of product quality.
