Hoping someone can help me with this, I am making a plate that has 108 holes in it 1.564 diameter. I am wanting to spiral in with a .500 carbide endmill to mill out the holes to within .015 of finished dimension. My CNC mill is a MV70C that doesn't have enough memory to allow this so I have tried using G90 to move to the holes X Y coordinates and then have a sub program in G91 that mills out the hole and the swithces back to G90 to move to the next hole coordinate. I have tried everything I know how but my problem is it wants to go back to the center of my plate (G57) and not mill out the hole at my G90 X Y coordinate. The reason for me trying this is to get away from using expensive posi drills which the inserts break without any warning and screws up a $450.00 posi drill. Any help will be greatly appreciated !! This is a copy of program
