数控车床特征曲线宏程序编程方法与技巧研究

CNC Lathe Catenary Macro-programming Method of Characteristic Curve

宏程序编制是以数学理论、公式及特征曲线等深入分析和计算为基础的。在宏程序编程中,首先要设置合适的自变量及其取值范围;其次要用数控编程语言进行编写及运行检验。本文介绍了实践中得出的编程步骤和三个编程实例,即正椭圆、抛物线及斜椭圆。实例有效地说明了特征曲线宏程序编程特点,有助于帮助编程人员更加深入地了解宏程序编程的实质。

The preparation of macro program is based on the analysis and calculation to the mathematical theory, formula and characteristic curve. In the macro programming, procedures firstly set appropriate independent variables and range;then NC programming language was wroten. The paper introduced the practice of the programming steps and three examples of programming,such as ellipse, parabola and ellipse oblique. This paper effectively illustrated the characteristic curve of macro programming features, it can help programmers more in-depth understanding of the macro programming.
