The busbar bending machine has the advantages of high processing precision, good dimensional stability, low labor intensity and convenient modern management. Bus processing machine belongs to numerical control equipment. In case of improper operation or programming error, it is easy to make the tool or tool holder hit the workpiece or bus processing machine. The light one will damage the tool and processed parts, and the heavy one will damage the components of bus processing machine, resulting in the loss of processing accuracy of bus processing machine. Therefore, it is not allowed to collide with the bus processing machine or workpiece during the use of the bus processing machine. The following is a detailed analysis of the reasons for the knife collision of the bus processing machine.

Because the busbar machine is locked by software, when the automatic operation button is pressed during simulation processing, whether the bus processing machine has been locked can not be seen intuitively on the simulation interface. There is often no tool setting during simulation. If the bus processing machine is not locked, it is very easy to collide with the tool. Therefore, before simulation processing, go to the operation interface to confirm whether the bus processing machine is locked. Forget to turn off the idle switch during processing. In order to save time, the empty running switch is often turned on during program simulation. Idle operation means that all moving axes of the bus processing machine operate at G00 speed. If the operation switch is not turned off during processing, the bus processing machine ignores the given feed speed and runs at the speed of G00, resulting in knife cutting and bus processing machine collision accidents. No return to the reference point after empty running simulation. When checking the program, the bus processing machine is locked, while the machining of the tool relative to the workpiece is simulated (the absolute coordinates and relative coordinates are changing). At this time, the coordinates are inconsistent with the actual position. The method of returning the reference point must be used to ensure that the zero point coordinates of the machine are consistent with the absolute and relative coordinates. If the machining operation is carried out without finding any problems after verifying the program, the tool collision will be caused. The direction of overtravel release is wrong.

When the bus processing machine is overtravel, press and hold the overtravel release button and move it in the opposite direction manually or manually, which can be eliminated. However, if the lifting direction is reversed, it will cause damage to the bus processing machine. Because when the overtravel release is pressed, the overtravel protection of the bus processing machine will not work, and the travel switch of the overtravel protection is already at the end of the travel. At this time, it may cause the worktable to continue to move in the over travel direction, and then pull the lead screw, causing damage to the bus processing machine. The specified line is not in the correct position when running. When a specified line is run, it is often executed downward from the position of the cursor. For the lathe, it is necessary to call the tool deviation value of the tool used. If the tool is not called, the tool running the program section may not be the required tool, which is very likely to cause a tool collision accident due to different tools. Of course, in the machining center and CNC bus bar machine, we must first call the coordinate system, such as g54 and the length compensation value of the cutter. Because the length compensation value of each knife is different, if it is not called, it may also cause knife collision.
