槽侧转角处的凹凸状R如图1所示的R_1和R_2,在加工过程中用通用R样板检测较为困难,若是槽小且深的情况下,就更困难了,从而影响产品质量。 据这一情况,我们自行制作了如图2所示的R样板。此样板经多年使用证明,使用方便、效果良好,制作简单。 Roughness at the corner of the groove R As shown in Figure 1, R_1 and R_2 are more difficult to detect with the universal R-plate during the machining process. If the groove is small and deep, it is more difficult to affect the product quality. According to this situation, we made our own R model as shown in Figure 2. This model after years of use proved that easy to use, the effect is good, easy to make.
