What are the programming skills of CNC machining? Let’s have a simple understanding:
1、 Using computer to imitate simulation system
With the development of computer technology and the continuous amplification of NC machining education, there are more and more NC machining simulation systems, and their performance is improving day by day. Therefore, it can be used to start the inspection procedure and watch the tool’s activity to determine if there is a possibility of collision.
2、 Using the imitation performance of CNC machining center
Generally, more advanced CNC machining centers have graphic display performance. After inputting the program, we can call the graph to simulate the performance and watch the moving track of the tool in detail, so as to check whether the tool may collide with the workpiece or fixture.
3、 The idling performance of CNC machining center
The accuracy of tool path can be tested by using the idling performance of CNC machining center. When the program is input into the CNC machining center, you may as well install the tool or workpiece, and then press the “idle” button. At this time, the spindle does not rotate, and the worktable automatically runs according to the program path. At this time, you may find out whether the tool may collide with the workpiece or fixture. However, in this case, it must be ensured that when the workpiece is installed, the cutter cannot be installed; when the cutter is installed, the workpiece cannot be loaded, otherwise there will be collision.
4、 Using the locking performance of CNC machining center
Generally, CNC machining centers have locking performance (full lock or single axis lock). After inputting the program, the z-axis is locked and the collision can be inferred by the coordinate value of z-axis. The use of this feature should avoid tool change, or the program can not pass.
5、 The configuration of coordinate system and cutter compensation must be accurate
When starting CNC machining center, the reference point of CNC machining center must be configured. The working coordinate system of CNC machining center should be consistent with that of programming, and it is more and more the target of Z axis. If there is a mistake, the possibility of collision between milling cutter and workpiece is quite large. In addition, the configuration of tool length compensation must be accurate, otherwise, it is either empty machining or collision.
The above is the CNC processing programming skills, I hope to help you.
