用坐标变换法扩展线切割机床的行程

从理论和实际两方面简要介绍了一种线切割机床的行程扩展技术。该技术的实质是将单向或双向跨度超过线切割机床行程的较大轮廓分成两个或多个加工阶段来进行加工，而在各个阶段之间，利用坐标变换技术改变工件的安装位置。实了际上，坐标变换技术是实现行程扩展的关键，而导向支架和长度标准块则是在具体机床上实现坐标变换的关键一环。文中同时介绍了实现这种技术的两个关键部件：导向支架和长度标准块的具体结构。

Spreading the Stroke of line-Cut Machine Tools by Coordinate Exchange

This article briefly introduces one kind of stroke spread technology of line-cut machine tools,from both theory and practice.The contour of workpiece which is larger than the stroke of machine toolsjn single direction or double direction span,can be processed by two or more processes.Between the two processes.the coordinate exchange technology is used to change the fix positions of workpiece.This article also introduces two important components that realized this technology:the particular structure of oriented support and length standard pieces.In practice,coordinate exchange technology is important for carrying out the stoke spread technology,the oriented support and length standard pieces is the hinge lind for realized coordinate exchange in the practicl machines.
