摘要
文章对数控铣削编程中零件尺寸公差对编程的影响、圆弧参数计算误差对编程的影响、两平行铣削面的阶差小于底部转接圆弧半径时的数学处理、行切法加工简单立体型面零件时行距和步长的确定等四个工艺问题进行了探讨,并提出了解决方案。
This paper concerns itself with ( 1 ) effects of the dimensional tolerance of parts on programming, (2) effects of the calculating errors of arc factors on programming, (3) math disposing when the distance between two parallel machined surfaces is smaller than the cutter' s working arc radius, and(4) the determinations of row spacing and step length when machining simple solid area parts in process planning in NC milling, and gives the soving methods.
