编程前的准备是指根据图纸要求和加工的具体条件,进行工艺分析、确定加工方法、切割路线、选择工艺参数等。主要包括: 1)确定能否进行线切割加工;2)充分利用现有条件,力求编程简便、快速、准确;3)妥善处理辅加程序。一、钼丝直径、放电间隙与编程的偏移量使用没有间隙补偿功能的线切割机时,编程需首先确定的是钼丝中心运动轨迹与切割轨 Pre-programming preparation refers to the drawing requirements and processing of specific conditions, process analysis, determine the processing methods, cutting routes, the choice of process parameters. Mainly include: 1) to determine whether the wire cutting can be processed; 2) make full use of existing conditions, and strive to programming simple, fast and accurate; 3) proper handling of auxiliary procedures. First, the molybdenum wire diameter, discharge gap and the programming offset Without gap compensation function of the wire cutting machine, the program must first determine the movement of the molybdenum wire center track and cutting rail
