1 INTRODUCTION
In recent years, numerical control technology developed rapidly, the ration rate C machine tools continuously improve C machine tools as the representative of the foundation of modern machinery has e China's manufacturing industry realized an important means of production modernization. Beijing No. 1 Machine Tool Plant production XKA5032 NC vertical C milling machine programming and operation of the system equipped with OKUMA OSP700M NC system, which many of the features of NC and other similar systems. In its resolution, the procedures of the pretreatment time, interpolation time, and so has a good performance. This article of the NC system programming methods and related issues.
2 basis for programming and format
Coordinate axis named
At present, the munity have adopted a uniform standard coordinate system, the NC machine ponents for mobile location and direction are used coordinate axis said. International standards (ISO) standards and China's Buban provided for in the machine coordinates Cartesian coordinates use of the right hand rule. Figure 1 is a vertical C milling machine coordinate system
determine the coordinates axis
(1) Z-axis
Z-axis is perpendicular to the direction of the axis milling machine spindle as Z direction, Z-axis tool away from the workpiece at the same time provides the direction for the Z-axis is the direction
(2) X-axis
X-axis is the level at the workpiece and the installation of telling parallel plane. The main provisions of the right post for the X-axis is the direction.
(3) Y-axis
Y-axis under the direction of Z, X axial right angle Cartesian c
