空间凸轮的计算机数控 (CNC)加工是现在最为常用的一种加工方法 ,而仿形加工中靠模凸轮的加工也是采用该法进行的 ,粗加工时采用比滚子直径小一些的刀具 ,精加工时就必须使用与滚子直径相同的刀具 ,本文给出了刀具尺寸误差 ΔR对凸轮轮廓法向误差 Δn影响的计算方法及规律
CNC machining of space cams is now the most commonly used machining method, and cam cam processing is also used in the profiling process, the roughing process using smaller than the diameter of the roller tool, fine The same tool diameter as the roller must be used in machining. This paper gives the calculation method and rule of the influence of the tool size error ΔR on the cam profile normal error Δn
