一、概述 机械加工过程中,经常是把工件安装在夹具中,夹具又安装在机床上。由于夹具是联系工件、刀具、机床的核心,因此在这种情况下夹具是影响工件加工精度的关键因素。本文着重研究有关夹具设计、制造精度的问题。 工作在夹具中加工时,造成表面加工误差(A.)的因素可分为如下? First, an overview Machining process, often the workpiece is installed in the fixture, the fixture is installed on the machine. Because the jig is the core of the workpiece, the tool and the machine tool, in this case, the jig is the key factor that affects the machining accuracy of the workpiece. This article focuses on the issue of fixture design and manufacturing accuracy. Work in the fixture processing, resulting in surface processing error (A.) The factors can be divided into the following?
