本文提出了一种在三轴铣床上加工自由曲面时有效刀具轨迹规划的解析方法。这种新方法使用了前一刀轨的非恒定偏移量,保证了刀具在零件表面的未加工区域运动,而没有冗余加工。该方法包括三个步骤:(1)计算刀具轨迹区间,(2)从路径区间到参数区间的转换,(3)有效的刀具轨迹规划的合成。
This paper presents an analytical method for planning an efficient tool-path in machining free-form surfaces on 3-axis milling machines. This new approach uses a nonconstant offset of the previous tool-path, which guarantees the cutter moving in an unmachined area of the part surface and without redundant machining. The method comprises three steps: (1) the calculation of the tool-path interval, (2) the conversion from the path interval to the parametric interval, and (3) the synthesis of efficient tool-path planning.
