Tips for CNC machining

We pay attention to efficiency and quality when we work, so we need some skills to achieve these two points. It is also a very good thing to learn to use some skills when we are processing. In the processing process of CNC machining center, it is very important to avoid collision of CNC machining center when programming and operating processing. Because the price is more expensive. Let’s take a look at what techniques can be used to avoid collisions?

  1. Using computer simulation system

With the development of numerical control system, simulation technology is more and more perfect. Therefore, it can be used in the preliminary inspection procedure to observe the movement of the tool to determine if there is a possibility of collision.

  1. Using the analog display function of CNC machining center

Generally, more advanced CNC machining centers have graphic display function. When the program is input, the graphic simulation display function can be called to observe the motion track of the tool in detail, so as to check whether the tool may collide with the workpiece or fixture

  1. Using the empty running function of CNC machining center

The correctness of the tool path can be checked by using the idle running function of CNC machining center. When the program is input into CNC machining center, the tool or workpiece can be installed, and then press the “empty run” button. At this time, the spindle does not rotate, and the worktable automatically runs 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 must be ensured that when the workpiece is installed, the tool cannot be installed; when the cutter is installed, the workpiece cannot be loaded, otherwise there will be collision.

  1. Using the locking function of CNC machining center

General CNC machining center has locking function (full lock or single axis lock). When the program is input, the z-axis is locked, and the collision can be judged by the coordinate value of z-axis. The application of this function should avoid the operation of tool change, otherwise the program can not pass.

  1. The setting of coordinate system and cutter compensation must be correct

When starting CNC machining center, the reference point of CNC machining center must be set. CNC machining center working coordinate system should be consistent with the programming, especially the Z axis direction. If there is an error, the possibility of milling cutter and workpiece collision is very large. In addition, the setting of tool length compensation must be correct, otherwise, it is either empty machining or collision.
