The best way I have found is to work with surfaces, have the caps on a different level, select all the surfaces including the cap, turn off the caps level then unselect the surface of the hole. Good luck

Seem to have got the problem sorted now, thanks to you guys and a lot of trawling through Fanuc manuals. It was the perameters that were just set too slow, they still need tweeking but know where I am going now. Thanks again. Tim

Have used a Thermwood in the past, the biggest POS I have ever used, no rigidity whatsoever. DON'T GET ONE

Hi The machine is a Mitsubishi DCH50 horizontal, it works fine without the G05 Q1, it's just that I need more cornering accuracy.

HI Guys Thanks for all your help so far. I have tried all your suggestions so far with no reward, with the P10000, the control throws up an error saying improper G code but it recognises G05 Q1. I'm thinking it must be the parameter settings in the control that is making it go so slow in the corners. Any more help greatly received. Tim

Yes it is but the tighten line or arc is not checked at the bottom of the box. Tim

Hi I am using surface finish contour with .02 mm tol on Mastercam X4. Tim

Thanks for the reply. Hi have tried searching through the manuals and the internet but it seems that the more I read the more confusing it gets. I have set the feed at 5.0 meters, which leaves rubbish definition, when I put in G05 at the start of the program it does a great job but takes 5 times longer. Surely there is a happy medium.

Hi, I am presently trying to use the G05 command on a Fanuc 18i- MB control, Yes, it does work but is too slow, I was wondering if anyone out there could give me any tips on setting the parameters in the control to get it cut more efficiently. Many thanks in advance.
