摘要
Polishing is an important finishing process in die and mold manufacturing. Hand polishing takes long time and much labor. Efforts are made to automate the polishing process while keeping accuracy. Recently grinding centers have been developed, which are used for free surface polishing in the present work. The new polishing technique applies the same cutting locus as used in the cutting process to remove only cusp height effectively, keeping the form accuracy generated in the cutting process.
擦亮是一个重要完成过程在死并且塑造生产。手擦亮花长时间和许多劳动。当保留精确性时，努力被作自动化擦亮的过程。最近磨擦的中心被开发了，它被用于免费表面在现在的工作擦亮。新擦亮技术使用在切的过程使用了有效地移开仅仅尖顶高度的一样的切地点，使形式精确性在切的过程产生了。
