Why does b-cutter appear when machining CNC?
January 30, 2023
Due to improper operation or programming errors during CNC machining, it is easy for the tool or tool holder to hit the workpiece or the machine tool. The lighter will damage the tool and the machined part, and the heavy machine will damage the machine tool parts and the machining accuracy of the machine tool will be lost. ,
During CNC machining, the dry run switch is often turned on in order to save time during program simulation. Dry running means that all motion axes of the machine are running at G00. When the machine is overtraveled, you should press and hold the overtravel release button and move it in the opposite direction by hand or by hand, which can be eliminated.
If the CNC machining time and space running switch is not closed, the machine ignores the given feed speed and runs at G00 speed, causing a knife or a machine crash. At this point, it is possible that the workbench will continue to move in the direction of the overtravel, eventually pulling the screw and causing damage to the machine. The cursor position is incorrect when the specified line is running.
There is no reference point after the dry run simulation. When the program is verified, the machine tool is locked, and the tool is CNC machined in the simulation operation (absolute coordinates and relative coordinates are changing). With the development of technology, tool damage detection, machine tool anti-collision detection, Advanced technologies such as machine tool adaptive machining can better protect CNC machine tools.
