一、问题的提出在使用数控线切割机床加工形状较复杂的工件时,为了检验程序是否正确,纸带有没有打错等,往往需先用薄料割制样板,如果被加工模具尺寸较大,那么割样板时不仅费料较多,且时间也很长,如能采取一种简单的“除2”线路,将每一段程序所有数值(包括X、Y座标和J计数长度)都缩为原来的1/2,这样,整个图形则缩为原来的1/4,用料及切割时间也缩为原来 First, the issue put forward In the use of CNC WEDM machining more complex shape of the workpiece, in order to test the program is correct, there is no wrong paper with the wrong, often need to cut the sample with thin material, if the mold is processed larger size , Then cutting the template is not only more expensive, and time is also very long, such as can take a simple “divide 2” line, each program all the values ​​(including X, Y coordinates and J count length) are reduced As the original 1/2, so that the entire figure is reduced to the original 1/4, materials and cutting time is also reduced to the original
