| Abstract: | The design scheme of clamping and locating in machining large-sized workpieces is put forward. By the stress analysis of workpiece in machining process or in practical application, the determining methods of supporting and clamping way for the workpiece are given. The location relationship between workpiece and machine tool is determined with applying three-dimensional measurement and conversion of coordinates to attain the goal that the workpiece can be accurately located with no adjustment. |
