摘要
为满足零件加工工艺要求，解决零件上尺寸精度、圆弧形状精度、相互位置精度。根据零件的用途、作用及外形、工艺要求，对该零件的加工工艺进行了详细的分析。机械加工工艺规程一般包括以下内容：工件加工的工艺路线、各工序的具体内容及所用的设备和工艺装备、工件的检验项目及检验方法、切削用量、时间定额等。
对罗拉齿形的加工，可以采用铣加工和刨加工，分析两种加工方式，选择了更加合适的刨加工，在加工时由于罗拉零件的特殊性，需要设计出一种专用于罗拉齿形加工的夹具体。在设计夹具时，要注意到工装夹具应具备足够的强度和刚度，夹具的可靠性和灵活性以及良好的工艺性。

Abstract

To meet the technological requirements of machining parts, solve the dimension precision, arc shape accuracy, mutual position precision. According to parts of the applications, function and appearance, technical requirements, the machining process of the part to carry on the detailed analysis. The machining process procedures generally includes the following content: workpiece machining processing route, the process of concrete content and used equipment and process equipment, workpiece inspection items and inspection method, cutting dosages, time quota etc.
For Laura tooth-type processing, can use milling and planing processing, analysis of two processing methods, chose a more suitable shaver processing, in processing the particularity of because Laura parts need to design a kind of dedicated to Laura tooth-type processing the clip concrete. In design fixtures, want to notice the fixture should have enough strength and rigidity, fixture reliability and flexibility and good workmanship.
