Machine tool collision can cause significant damage to the accuracy of machine tools, and the impact varies among different types of machine tools. Generally speaking, it has a greater impact on machine tools with weak rigidity. So, how does a CNC numerical control center prevent machine tools from colliding?

The main cause of the collision:
One is the incorrect input of the diameter and length of the cutting tool;
The second is incorrect input of the workpiece's dimensions and other related geometric dimensions, as well as incorrect initial positioning of the workpiece.
The third reason is that the workpiece coordinate system of the machine tool is set incorrectly, or the zero point of the machine tool is reset during the processing, causing changes. Most machine tool collisions occur during the rapid movement of the machine tool, and the hazards of collisions that occur at this time are also the greatest. They should be absolutely avoided.
Therefore, the operator should pay special attention to the initial stage of the machine tool's program execution and when the machine tool is changing tools. At this time, if the program editing is incorrect or the diameter and length of the tool are input incorrectly, a collision is very likely to occur. At the end of the program, if the sequence of the tool withdrawal actions of the CNC axis is incorrect, a collision may also occur.
To avoid the above-mentioned collisions, when operating the machine tool, the operator should fully utilize the functions of their five senses to observe whether the machine tool has any abnormal movements, sparks, noises or unusual sounds, vibrations or a burnt smell. If any abnormal situation is found, the program should be stopped immediately. The machine tool can resume operation only after the problem is solved.
