How can CNC machining avoid collisions?

CNC machining is a nightmare for machine operators. Small ones can smash workpieces tools, large ones can destroy people. In any case, in cnc CNC machining, try to prevent the appearance of hitting the knife.

For CNC machining centers, CNC machine tools have high machining accuracy, good scale stability, low labor intensity. However, due to improper operation programming errors, it is easy to cause the tool tool holder to hit the workpiece machine tool. the parts to be processed, the heavy ones will damage the machine tool components, so that the machining accuracy of the machine tool is lost, even form a personal matter. Therefore, we must find the cause of the collision reduce the occurrence of these errors.

Because the CNC machining center is locked with software, when imitating the process, when the automatic operation button is pressed, the imitation interface cannot intuitively see whether the machine tool is locked.

When imitating, there is often no tool setting. If the machine tool is locked, it is very easy to hit the tool, so before imitating processing, you should go to the operation interface to recognize whether the machine tool is locked.

I forgot to turn off the dry run switch during processing, because when the program is imitated, in order to save time, the dry run switch is often turned on. Dry run means that all the motion axes of the machine tool run at the speed of G00. If the spatio-temporal operation switch is turned off during processing, the machine tool ignores the given feed speed runs at the speed of G00 to form a knife machine accident.

When the machine tool is overtraveled, you should press hold the overtravel relief button move it in the opposite direction manually manually to eliminate it. But if the direction of exemption is reversed, it will cause damage to the machine tool. When the overtravel exemption is pressed, the overtravel maintenance of the machine tool will work, the stroke switch of the overtravel maintenance is already at the end of the stroke. At this time, it may cause the workbench to continue to move in the direction of overtravel, eventually the screw , The machine tool is damaged, the cursor position is incorrect when the specified line is running.

Of course, you must first call the coordinate system such as G54 the length compensation value of the tool in the machining center CNC milling machine. Since the length compensation value of each knife is different, it may form a collision knife if it is called.
