在机械零件加工中,倒角是经常碰到的工序,有的倒角要求不高,只是去除毛刺锐角,或者为了装配方便。但有的零件要求较准确的倒角大小、角度和圆角R。例如在轴承加工中倒圆角就要求比较高,并且列为外观质量检查项目之一。在零件加工中,倒角的测量和检查都不方便,往往使倒角达不到图纸要求。我们自制了一种倒角测量样板(图1),可以直接测量45°(图2)、30° In the machining of mechanical parts, chamfering is often encountered in the process, and some chamfering less demanding, but to remove burr acute angle, or to facilitate assembly. But some parts require a more accurate chamfer size, angle and rounded R. For example, the fillet in the bearing processing requirements are relatively high, and as one of the appearance quality inspection items. In the parts processing, chamfering measurement and inspection are not convenient, often do not meet the drawings chamfered requirements. We made a chamfer measurement model (Figure 1), which can directly measure 45 ° (Figure 2), 30 °
