Compared with ordinary machine tools, water wheel rotary transfer machine has the advantages of high precision, good dimensional stability, low labor intensity and convenient modern management. However, due to improper operation or programming errors and other reasons, it is easy to make the tool or the tool holder hit the workpiece or the machine tool, the light will crash the tool and the parts to be processed, the heavy will damage the machine tool parts, so that the processing accuracy of the water wheel rotary transfer machine is lost, and even cause personal accidents.

From the point of view of maintaining accuracy, when using the water wheel rotary transfer machine, the tool must not collide with the machine tool or the workpiece. The following, for the Posen NUMERICAL control collision knife induction and analysis, I hope to help you.

Skew rail CNC lathes brand analog machining machine does not lock. Since the water wheel rotary transfer machine is locked by software, in the simulation process, when the automatic operation button is pressed, whether the machine tool is locked cannot be visually seen on the simulation interface. There is often no tool in the simulation, and if the machine tool is not locked to run, it is easy to bump the knife. Therefore, before the simulation processing should go to the running interface to confirm whether the machine is locked.

Forget to turn off the no-run switch during processing. Because the water wheel rotary transfer machine is in the program simulation, the empty operation is often switched on to save time. Running empty means that all axes of motion of the machine are running at the speed of G00. If the switch is not turned off in both processing space and time, the machine will ignore the given feed speed and run at the speed of G00, resulting in an accident of punching and hitting the machine.

No reference point is returned after running the simulation empty. In the verification program when the machine is locked motionless, and the tool relative to the workpiece processing in the simulation operation (absolute coordinates and relative coordinates change), this time the coordinates do not match the actual position, must use the method of returning the reference point to ensure that the mechanical zero coordinates are consistent with the absolute and relative coordinates. If the machining operation is carried out without finding the problem after the verification procedure, it will cause the collision of the tool.

The direction of overshoot release is wrong. When the turning and milling compound machine tool overruns, it should press and hold the overruns release button, and move in the opposite direction manually or by hand, that is, it can be eliminated. However, if the direction of lifting is reversed, it will cause damage to the machine tool. Because when the overrange release is pressed, the overrange protection of the machine tool will not work, and the stroke switch of the overrange protection is already at the end of the stroke. At this time, it is possible to cause the workbench to continue to move in the direction of excess, and eventually pull the lead screw, causing damage to the machine tool.

The cursor position is incorrect when the specified line is running. When a specified line is run, it is usually executed downward from the cursor position. For the lathe, it is necessary to call the tool offset value of the tool used, if the tool is not called, the tool running the program segment may not be the desired tool, and it is very likely to cause a collision accident due to different tools. Of course, in the machining center, CNC milling machine must first call the coordinate system such as G54 and the length compensation value of the knife. Because the length compensation value of each knife is not the same, it is possible to cause knife collision if it is not called.
