Joined Nov 19, 2007 Location Chatsworth, California Posted this on the CNC Machining group but... only crickets. <g> So... Anyone here using G43.1 on a 5ax mill? My one customer is using my posted code with no G43.1 (or .4). They don't understand it so can't tell me what I need to post. My post currently is configured with the pivot and actual tool length (Zoff) calculated for output. Inverse feeds and all work well. The problem is if they change a tool and it's off in set length (which it usually is), they want me to re-post it (every time!). I've found some sample code of how it should look posted below.

The actual gauge length? Are there any other parameters to setup in the control? I read about nc parameter value 19666 needing attention as well. There's G43.4 as well but I don't think it's on the 15m. Anyone? -- Bill J

Joined Dec 16, 2006 Location Los Angeles, California It isn't that simple Bill. G43.1 and G43.4 work differently. G43.1 is for inverse time/continuous motion applications. G43.4 is for 3+2 stuff where you want to use G41.2, for instance. Your AICC command might seem to be useful but it's probably just adding to the run time. I'll explain this if you'd like. There are several parameter setting that your customer will have to make and a fairly simple way to alter them. I don't remember seeing this on AMC. What's the pivot distance? JC

From my fuzzy memory (it's been a few years), my old posts (GPM before UGPost) would output inverse time with the pivot and (approx) gauge length both calculated. What I couldn't remember under G43.1 was if the operator enters the actual offset at the the control or the difference between my calculated value vs. the actual. I can output Zoffset so the program output is at tool tip. That make me think they enter the diff. Then I recalled there was a parameter for the pivot value. The problem lies in the fact I've had the luxury of programming updated MDSI and PC2100 controls on the head/head machines for the past few years. The rest were trunions which didn't matter. "G43.4 is for 3+2 stuff where you want to use G41.2, for instance." Here's a link I got the samples of G43.1 and G43.4 from. It's a Catia users group but the information looked appropriate: http://shorterlink.org/7155 I assumed G43.4 was out of the question as it's an additional cost option that I know the owner would not have. "Your AICC command might seem to be useful but it's probably just adding to the run time." Maybe...mayber not. Without knowing the controls behavior beforehand, I would stick that in to insure the readahead didn't miss it at first. "I'll explain this if you'd like. There are several parameter setting that your customer will have to make and a fairly simple way to alter them." Thanks for the help but... I had to move forward <g>. There was no money in it to keep dealing with "their" issue. Now, if it was a client I saw a real future with..? "I don't remember seeing this on AMC." I would NEVER post such a specific question there for obvious reasons. Also, since I started kill-fileing just a few posters there, it's an almost dead group! <g> -- Bill You must log in or register to reply here.
