近十几年来电火花线切割加工工艺在国内外得到了很大的发展,为了满足工业生产特别是模具加工要求,线切割机床取得了较大的进展。随着模具加工的发展和机床电气可靠性的提高,用户对机床的加工精度越来越感兴趣,相应提出了更高的要求。对于机床而言,应当是加工出符合人们要求的工件。机床的加工精度是加工中不可靠性的度量。具体地讲:是用加工件在尺寸、形位以及光洁度等方面达到的准确程度来衡量。加工精度基本是由机床的工作精度和非机床本身产生的误差而组成,机床的工作精度是机床工作不可靠性的度量;非机床本身的误差是由环境、人、测量方法、操作方法等
In the last ten years, WEDM has been greatly developed at home and abroad. In order to meet the requirements of industrial production, especially mold processing, WEDM has made great progress. With the development of mold processing and the improvement of the electrical reliability of the machine tool, the user is more and more interested in the machining accuracy of the machine tool and correspondingly sets higher requirements. For machine tools, it should be processed to meet the requirements of the workpiece. Machine tool machining accuracy is measured in the unreliability. Specifically: the workpiece is measured in terms of size, shape and finish, etc. to measure the accuracy. The machining accuracy is basically composed of the working accuracy of the machine tool and the error caused by the machine itself, and the working accuracy of the machine tool is a measure of the unreliability of the machine tool. The error of the non-machine tool itself is determined by the environment, people, measurement methods, operation methods, and the like
