CAD files can be imported directly into UG. Generate a program for trademark processing graphics, then generate a CNC machining program, and transfer it directly to the machine tool. Before each processing, you only need to enter the offset value of the coordinate system into the program, then use this value to specify a temporary coordinate system, and then start the program. processing, so that the trademark processing program can be directly called on the machine tool without the need for accurate shaping and programming of each piece.
