目针对SINUMERIK-802D数控系统的后置处理技术的研究与实现
摘 要
基于MasterCAM通用后置处理系统,应用数控代码导向技术,通过修改其数据库模型,较好地开发配置SINUMERIK-802D数控系统的XK715数控镗铣床的专用后置处理程序,解决了该系统处理孔加工固定循环的难题,并成功应用于实际加工。通过实践验证,本系统能够直接处理轮廓、内槽、孔系、曲线及曲面的刀具路径文件,不需人工再做2次处理。

Abstract
Post processing technology is one of the main technology of NC machining programming, it is the connection of CAD/CAM system and mechanical machining, it directly affects the applying affection, machining quality, effect and dependable running of auto-programming software. This text explicates the content, structure and function of post processing, analyses to compare the special post processing systems procedural structure and operational process with the general post processing systems, questions the post processing procedures key problem-the algorithm principle of post processing, it studies the three-axiss machining, the cutter location computation of multi-axiss and the feed rate of multi-axiss running, studies and compares the general cutter location files form of CAD/CAM systems. It contains the codes character of SINUMERIK-802D NC system on hole machining constant cycle; analyses the cutter location files’ structure of MasterCAM system; studies the machine tools specified files’ design and making methods. This text points out that the general post processing system is the developing direction of CAD/CAM systems, but basing on the need of projects practical application, its necessary to study and develop the post processing of extensively used CAM software.
This text is basing on the general post processing system of MasterCAM, using NC code leading technology, by modifying its database model, it develops and disposes SINUMERIK-802D NC systems special post processing procedure of XK715 NC milling machine, solves the problem of dealing with hole machining constant cycle and applies to practical machining. Through practical application, this system can deal with the cutter tool path file of counters, groves, holes, curves and surfaces directly, not need to do second-managing.
Key Words: NC Machining Technology; NC System; MasterCAM ;Cutter Location File; Post Processing ; The Specified File of Machining Tool
