大家都知道,样形刀的设计与制造存在着许多困难,所以我厂工艺员和工人共同研究一种加工样形刀成形表面的新方法。这种方法,简化了设计与制造测量样形刀成形表面用的样板。样板的作法是,首先加厚样板,它的测量部分要完全符合零件的截面形状,然后根据样形刀的前角γ把样板去 As we all know, there are many difficulties in the design and manufacture of the prototype knife. Therefore, our factory craftsmen and workers work together to study a new method of machining the surface of the prototype knife. This method simplifies the design and manufacture of templates for measuring the profiled surface of a prototype knife. The model approach is, first of all thickened model, the measurement of its part to fully comply with the cross-sectional shape of the parts, and then according to the rake angle sample before the model to go γ
