在日常机械加工中,我们有时会遇到两个弧型面交点尺寸的测量问题。图1所示就是我厂线切割机床在机械加工中,经常遇到的一种零件简图。由于该零件的在图纸中,标注了尺寸L_1和L_2,即需要最终保证用尺寸L_1和L_2来控制两弧型面交点的位置。所以零件加工后需要测量出L_1和L_2的值,以便确定零件加工后的两弧型面交点所处位置是否达到图纸要求。但是由于现有通用计算器具的限制,有特殊要求的零件
In routine machining, we sometimes encounter the problem of measuring the intersection point of two arcs. Figure 1 shows my factory wire cutting machine in machining, often encountered a kind of parts diagram. As the parts in the drawings, marked the size of L_1 and L_2, the need to ensure the size of the final L_1 and L_2 to control the location of the intersection of the two arc-type surface. Therefore, after the part is machined, the values of L_1 and L_2 need to be measured so as to determine whether the intersection of the two arc-shaped surfaces after the part is processed meets the requirements of the drawing. However, due to the limitations of existing general purpose computing equipment, there are special requirements for parts
