How to improve the programming technology of CNC machining

Programming is an indispensable step in the For CNC machining centers, we must avoid collisions during programming and machining. Because the CNC machining center is very expensive, ranging from hundreds of thousands of yuan to millions of yuan, the maintenance cost is quite expensive. Below I will share with you some programming skills on how to improve CNC machining.CNC machining process, but many beginners know very little about CNC machining programs.

Technology 1: Use the CNC machining center to come with simulation display function

Usually, the more advanced CNC machining centers have graphic display functions. After entering the program, you can call the graphic simulation display function to observe the tool's movement trajectory in detail to check whether the tool and the workpiece or fixture may collide.

Technology 2: Application of computer simulation system

With the development of computer technology and the expansion of CNC machining teaching scale, more and more CNC machining simulation systems have become increasingly perfect. In this way, it can be used to initially test the procedure and observe the movement of the tool to determine whether there is a collision.

Technology 3: Utilize the locking function of CNC machining center

Ordinary CNC machining centers have locking function (full lock or single-axis lock). After entering the program, lock the Z axis and determine whether a collision will occur by the coordinate value of the Z axis. When applying this function, you can avoid tool change and other operations, otherwise the program will not be able to pass.

Technology 4: Coordinate system, tool repair setting must be correct

When starting the CNC machining center, be sure to set the CNC machining center reference point. The working coordinate system of the CNC machining center should be consistent with the programming time, especially in the Z-axis direction. If there is an error, the possibility of the milling cutter contacting the workpiece is very high. In addition, the tool length compensation setting must be correct, otherwise empty processing or collision cannot be used.

Technology 5: Utilize the idle function of CNC machining center

Through the idle function of the CNC machining center, the correctness of the tool trajectory can be checked. After entering the program in the CNC machining center, the tool or workpiece can be loaded and the empty key can be pressed. At this time, the spindle does not rotate and the workbench will automatically run according to the program track. At this time, the machine tool can find whether the tool or workpiece is touching. However, in this case, it is necessary to ensure that the tool cannot be equipped with a knife when the workpiece is installed; when the tool is installed, the workpiece cannot be installed, otherwise a collision will occur.

Technology 6: Improve programming skills

Programming is a key link in CNC machining. Improving programming skills can largely avoid some unnecessary conflicts.

In short, mastering the programming skills of CNC machining centers can better improve processing efficiency and processing quality, and avoid unnecessary errors in processing. It requires novices in CNC machining centers to continuously summarize their experience and improve them in practice, thereby further enhancing their programming and processing capabilities. If beginners don’t know much about these aspects, they should learn more and consult experienced technicians.
