SCIENCE AND TECHNOLOGY ENGLIAH FOR MECHANICAL ENGINEERING A set-up consists of locating and clamping of a workpiece. After locating, the workpiece is in a locating 定位 correct position relative to the machine tool or workholder Clamping is used to fix the workpiece clamping **n at the located position. If an operation contains only a single locating and clamping operation, it is workholder said that this operation is performed in a single 工作夹具 set-up as shown in Fig. 6.2(a) where two milling cutters are used simultaneously to mill the two sides of the workpiece Therefore, the term"set-up"has two different meanings 1.
