For the general machine tool CNC machining center, the NC machine has high machining accuracy, good dimensional stability, low labor intensity, and convenient for modern management. However, because of improper operation or programming errors, the tool or tool holder is easily hit on the workpiece or machine tool. The light person will break the tool and the machined parts. The heavy person will damage the machine parts, so that the machining accuracy of the machine tool will be lost and even the personal accident will be caused. Therefore, from the point of view of maintaining accuracy, it is not allowed to collide with the machine tool or workpiece in the use of NC machine tools. The following causes of the collision knife are summarized and analyzed.
As the CNC machining center is locked by software, when the automatic operation button is pressed, it is not intuitively locked in the simulation interface when the automatic operation button is pressed. In simulation, there is no tool setting. If the machine is not locked, it is easy to hit the knife. So before the simulation processing, we should confirm whether the machine is locked or not. Forget to turn off the empty operation switch when processing. In the process of program simulation, the idle operation switch is often opened to save time. Empty operation refers to the movement of all moving axes of machine tools at G00 speed. If the switch is not turned off in the processing time and space, the machine tool ignores the given feed speed and runs at G00 speed, resulting in an accident of cutting and hitting the machine tool. There is no return to the test point after the air operation simulation. When the program is checked, the machine tool is locked, and the tool relative to the workpiece is processed in the simulated operation (the absolute coordinates and the relative coordinates are changed). The coordinates of the machine are not in conformity with the actual position, and the method of returning the reference point should be used to ensure the zero point coordinates of the machine and the absolute and relative coordinates. If the problem is not found after checking the program, the machining operation will result in the collision of the tool. The direction of the override is not right.
When the machine tool overruns, it should hold down the over lift button and move it in the opposite direction by manual or manual way, that is, it can be eliminated. However, if the direction of release is reversed, it will cause damage to the machine tool. Because the overshoot protection of the machine will not work when the overload is lifted, and the travel switch of the override protection is at the end of the journey. At this time, it is possible to cause the worktable to continue to move in the direction of overshoot, eventually leading to failure of the lead screw, resulting in damage to the machine tool. The specified line running time mark position is unsuitable. When a specified row is running, it often starts down from the cursor position. For the lathe, it is necessary to call the tool bias of the tool used. If the tool is not called, the tool in the running section may not be the tool required, and it is very likely to cause the tool accident because of the different tool. Of course, in the machining center and CNC milling machine, we must first invoke the coordinate system, such as G54 and the length compensation value of the knife. Because each knife’s length compensation value is different, if not invoked, it may cause collision knife.
1.CNC machining center CNC machine tool, as a high precision machine tool, is very necessary to prevent collision. It requires the operator to develop the habit of careful careful and careful, to operate the machine tool in the correct way, and to reduce the phenomenon of machine tool crashing. With the development of technology, the advanced technologies such as tool damage detection, machine tool collision detection and machine tool adaptive processing have appeared in the process of processing, which can better protect CNC machine tools.
