In the machining process of CNC machining center, it is very important to strictly prevent the collision of CNC machining center when programming and manipulating machining. Because the value of CNC machining centers is very high, ranging from several hundred thousand yuan to several million yuan, the maintenance is difficult and the cost is high. However, collisions are a rule to be followed and can be prevented. We might as well summarize the following points.

1. Using computer simulation system

With the development of computer technology and the continuous enlargement of CNC machining education, there are more and more CNC machining simulation systems, and their performance is also increasing day by day. Therefore, it can be used to start inspection procedures, observe the activity of the cutting tool, and determine whether there is a possibility of collision.

2. Utilize the imitation performance of CNC machining center

Generally, the more advanced CNC machining centers have graphics capabilities. Once in the program, you may want to call up graphics to simulate performance and observe the tool's path in detail in order to check if the tool might collide with the workpiece or fixture.

3. Utilize the emptying performance of CNC machining center

The accuracy of the tool path can be tested by using the dry run performance of the CNC machining center. When the program is input into the CNC machining center, it may be necessary to install the tool or workpiece, and then press the empty operation button, the spindle will not rotate, and the worktable will automatically run according to the program tracking. At this time, it may be necessary to check whether the tool and the workpiece or the fixture. However, in this case, it is necessary to ensure the workpiece and do not install the tool; when installing the tool, the workpiece cannot be installed, otherwise a collision will occur.
