X8 Bull bug

Recommended Posts

Has anyone noticed if you change a bull diameter it automatically changes the radius to 1/4 of the diameter?  We had a 6MM x .5MM bull that the operator changed the diameter  by .0004 and the corner radius went from .0197 to .059.  It seems no mater what diameter you put in it updates the corner radius to 1/4 the diameter entered.  It does it on all our PC's.  We have to go back to X7 till a fix is issued...too easy to make a mistake.

I'm not denying that there's a problem here that needs to be fixed, but don't you have all of your tools defined in your tool library? You shouldn't have to change diameter of the tool.

You can grab a tool and hold .0001/.0002?  We laser all our tools then the operator puts in the diameter and regenerates the program.

We are hard milling parts on our ROKU and the tangs have a .0003 (.00015 P/S) tolerance.  We mill down far enough to measure the width then adjust the cutter and regenerate the program if needed.  Our mill guy has done very well with knowing how much to "adjust" for flex and spring on the diameter from the laser measurement.  It really isn't that hard when you have a tight accurate machine and cutters.

 

The parts are programmed from solids using surface toolpaths so CC is not an option.
