摘要 本文是对手柄(C1318自动车床手柄)零件加工应用及加工的工艺性分析，主要包括对零件图的分析、毛坯的选择、零件的装夹、工艺路线的制订、刀具的选择、切削用量的确定、加工工艺文件的填写。选择正确的加工方法，设计合理的加工工艺过程。此外还对手柄(C1318自动车床手柄)零件的两道工序的加工设计了专用夹具. 机床夹具的种类很多，其中，使用范围最广的通用夹具，规格尺寸多已标准化，并且有专业的工厂进行生产。而广泛用于批量生产，专为某工件加工工序服务的专用夹具，则需要各制造厂根据工件加工工艺自行设计制造。本夹具设计的主要内容是设计手柄(C1318自动车床手柄)钻床夹具设计。 关键词：手柄(C1318自动车床手柄)，加工工艺，加工方法，工艺文件，夹具 Abstract This article is for the beari
