ZT006零件的机械加工工艺规程和夹具设计
摘要
本文是对ZT006零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ZT006零件的一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。本论文夹具设计的主要内容是设计ZT006钻床夹具设计。
关键词：ZT006零件，工艺，工序，切削用量，夹紧，定位，误差

This paper is the analysis of the machining process of ZT006 application and processing, including the parts diagram analysis, the choice of blank, parts of the fixture and process planning, tool selection, cutting, processing documents. Choose the correct processing methods, design the reasonable process. In addition, processing procedure of ZT006 parts of the design of special fixture.
Many kinds of the machine tools fixture, the fixture's most widely used, the size has been standardized, and there is a professional factory production. But widely uses in the volume production, special fixture for a workpiece machining processes and services, to the factory according to the workpiece machining process to design and manufacture. The main content of this paper is the design of drilling jig and fixture design ZT006 design.
Keywords: ZT006 parts, process, process, cutting, clamping, positioning error
