With the rapid development of industry, our processing methods are also increasing. There were few methods in the past, but now there are many. The same is true for CNC precision parts processing. Let me tell you about CNC parts processing and programming skills.
1、 Computer simulation system
With the development of computer technology and the expansion of NC machining teaching, there are more and more NC machining simulation systems and their functions are becoming increasingly perfect. Therefore, it can be used in the preliminary inspection program to observe the movement of the tool to determine whether there is a possibility of collision.
2、 Application of locking function of cnc machining center
CNC parts machining centers for electrical appliances and hardware have locking functions (full lock or single shaft lock). After entering the program, lock the Z axis, and judge whether the collision will occur through the coordinate value of the Z axis. The application of this function should avoid tool change and other operations, otherwise the program cannot pass through.
3、 Improve programming skills
Programming is a crucial link in NC machining, and improving programming skills can prevent unnecessary collisions to a large extent.
4、 The application of the imitation display function provided by the non-standard CNC machining center The common and more advanced CNC part machining centers have the graphic display function. When the program is input, the function of graphic simulation display can be called to carefully observe the moving track of the tool, so as to check whether the tool may collide with the workpiece or fixture.
5、 The coordinate system and cutter compensation must be set correctly
When starting the CNC part machining center, be sure to set the CNC part machining center reference point. The working coordinate system of Kunshan CNC parts machining center should be different from that of programming, especially in the Z axis direction. If there is an error, there is a great possibility that the milling cutter will collide with the workpiece. In addition, the tool length compensation must be set correctly, otherwise, it will be either empty machining or collision.
6、 Application of idle running function of CNC parts machining center
The correctness of tool path can be checked by using the idling function of CNC part machining center. When the program is input into the CNC part machining center, the tool or workpiece can be installed, and then press the idle operation button. At this time, the spindle does not rotate, and the workbench automatically operates according to the program path. At this time, it can be found whether the tool may collide with the workpiece or fixture. However, in this case, it is necessary to ensure that the tool cannot be installed when the workpiece is installed; When installing the tool, the workpiece cannot be installed, otherwise it will collide.
