中心钻孔的正五边形钳工加工工艺分析

对中心钻孔的正五边形工艺方法进行了分析,针对大多操作者工艺方法上的不足之处,提出利用直角三角形勾股定理,在保证角度和孔心位置的同时,保证边的精度及各边到顶点的距离,同时采用对称加工原则,减少误差累积,从而最大限度减小了正五边形的＂变形＂。

Benchwork Machining Process Analysis about the Regular Pentagon with a Hole

The manufacture process about the regular pentagon with a hole was analyzed.For the unreasonable method from most operators, the Pythagorean theorem was used to assure edge precision and vertex to edge distance as so as angle precision, circle center position. Meanwhile, semmetry processing principle was used to decrease error accumulation.The method could decrease regular pentagon deformation.
