我厂像全国各厂一样,随着祖国建设的需要,产品品种也随之复杂;标准零件图纸的供应,也在要求保证质量的基础上大量增加。虽然我厂已开展了标准化工作,但标准件仍要发一定数量的图纸。因此,我们在技术革新运动中,在如何能节省图纸的原则上,创造了一种工具──标准零件尺(图1)并已 Like our factory in our country, with the construction of the motherland, the variety of products is also complicated. The supply of standard parts drawings also increases greatly on the basis of ensuring the quality. Although our factory has carried out standardization, but the standard parts still have to send a certain number of drawings. Therefore, in the process of technological innovation, we have created a tool on the principle of how to save the drawings - the standard parts ruler (Figure 1) and
