在万工显上对图1所示开口样板交点尺寸a进行测量时,因开口样板的直槽与斜槽的交点O难找,所以不象看起来那样容易测量。本文介绍一种简单直观的方法,供这类样板交点尺寸测量时参考。图1所示样板厚度为5mm,交点尺寸a=60mm,槽面表面粗糙度Ra=0.8μm,平面度符合样板图纸 In all workers on the opening model shown in Figure 1 intersection size a measurement, due to the opening template straight groove and chute intersection O hard to find, so not as easy to measure as it seems. This article presents a simple and intuitive method for reference when sizing such cross-point measurements. Figure 1 shows the thickness of the sample 5mm, intersection point size a = 60mm, groove surface roughness Ra = 0.8μm, flatness in line with the template drawings
