I have to run a mill with a Heidenhain 530 control and it's very, very common here to mill pockets that are open on one side(same thing with closed pockets I guess) . These controls are so limited with options(cycles) and have no open pocket cycles so a person has to use the std pocket cycle and cheat the pocket so it is wider so it "overshoots" the part edge(and wastes time cutting air) . So I'm just long handing it but when a person runs multiple passes( first pass is outside perimeter then spiraling inward, on closed pockets I usually go inside to out, it just ends with more air cutting on open pockets) with say 80-85% stepover the corners leave those wedges . In G-code(Fanuc style)mills I'm used to I would to just program a negative R value and the mill would do a quick loop in the corners and take care of those wedges .The 530 won't allow Radius values unless I have cutter comp on, but even then it'll just do the standard corner radius and will leave some nubs . Anyone know any tricks to these controls to take care of the corners without doing 5 million passes and only using 40-50% stepovers ?
