Collision is no small matter. In the CNC machining process of small machining centers, if a collision occurs, the workpiece will be scrapped, or the spindle will be damaged, which will seriously affect the order progress, processing efficiency, and damage the service life of the machining center. Although the collision phenomenon cannot be completely avoided, it can be prevented to the greatest extent by using the correct processing method.
Is it difficult to prevent collisions? In fact, the built-in functions of small machining centers can be well prevented.
Today's machining center operating systems basically have the "single segment execution" - SigleBlock function. This button determines whether you have the opportunity to stop after making a mistake. Before the processing order is "started by cycle", we must make sure that the next action of the machine is exactly as you expected. If you are not sure what action the machine will perform next, then it is best not to press the "cycle start" button . In order to avoid unnecessary processing waste in the case of uncertain processing procedures.
The "single segment execution" function is an important part of this rule. In the case of program changes, tool changes, coordinate system changes, etc., this function will effectively reduce the consequences of collisions caused by mistakes.
In daily processing, after the programmer writes the program, the operator needs to carry out the next operation according to the tool list and program list.
Programmers need to simulate the processing conditions in advance as much as possible to discover possible dangers in the processing as early as possible, and check again after obtaining the post-processing program. Giving operators unverified processing procedures will damage mutual trust and increase the psychological pressure on both parties, and at the same time, it cannot effectively avoid the occurrence of collisions.
