基于VB的数控刨床加工程序的自动生成

数控刨床加工柱型曲面类特型工件时,必须将工件型线采用小直线段来近似逼近,并采用断续插补工作方式.为了避免此类冗长数控程序繁复的人工编制过程,设计了数控刨床程序自动生成软件.该软件能够在人机界面上仅输入已知的曲面型线表达式,然后使用一些字符串处理函数,自动识别表达式并转换为程序计算表达式,计算曲线的坐标点串并加以整理,进而基于此坐标点串,判断刀补情形,决定调用何种合适的宏程序,自动生成加工用数控程序,还可以进行数控加工模拟.该软件已在实际生产中使用,所生成的数控程序符合加工需求,切实可用.

Numerical Control Planer Program Processing Automatic Generation Based on VB

When numberical control planer processed the surface of cylindrical work pieces, the outline of component profile is usually approximated using a series of short lines in an intermittent interpolation work way. Software which produces programs automatically for NC planer is designed in order to avoid the long artificial editing process for the numerical control procedure. Known surface line expressions are inputted via the human-computer surface, recognized by well-designed character-string-processing function and transformed into expressions for program. The software calculates and arranges the curve coordinates, determines approximation types and calls corresponding macro pro- grams to form NC processing programs automatically. The software can also simulate NC processing and has been used in practice. The NC programs produced meet the requirements of processing and are applicable.
