一、切割超大工件座标定位的方法我们厂的厂标(图1)外形尺寸为360×360mam,而我们最大的线切割机床是苏州长风厂生产的DK7732。其加工范围为320(x轴)×500(y轴),而工件两侧面也无法加工出定位基面,我们则采用了以销孔座标找正定位的方法,进行两次装夹切割,具体方法如下: First, the method of cutting large workpiece coordinate positioning Our factory standard (Figure 1) dimensions of 360 × 360mam, and our largest wire cutting machine is produced in Changfeng Chang Suzhou DK7732. The processing range of 320 (x axis) × 500 (y axis), and the workpiece can not be processed on both sides of the positioning of the base surface, we use the pin hole coordinates to find a positive positioning method, the two clamping cutting, Specific methods are as follows:
