研究了超精密光栅铣削加工自由曲面时的切削策略。自由曲面加工中的切削策略研究涉及到切削参数的选择和刀具轨迹的规划。本文建立了一个完整的系统，用于开发光栅铣削自由曲面的切削策略，自动生成数控程序，模拟刀具轨迹和加工过程，以及预测加工时间和表面质量。实验结果表明，该系统适用于UPRM中自由曲面的加工。因此，这项研究有助于避免需要进行昂贵和耗时的试切试验，以确保产品质量的自由曲面加工。
This paper studies the development of cutting strategy in the fabrication of freeform surface in ultra-precision raster milling (UPRM). The tasks of developing cutting strategy in freeform machining involve in the selection of cutting parameters and the planning of tool paths. An integrated system is built in this study to develop the cutting strategy, automatically generate NC program, simulate the tool paths and machining process, as well as make predictions for the machining time and the surface quality of the raster milled freeform surface. Experiment is conducted to verify the developed system and the experimental results show that the system is applicable for the machining of freeform surface in UPRM. This study therefore contributes to avoiding the need to conduct expensive and time consuming trial cutting tests to ensure the product quality in the freeform machining.
