Help with expert machinist G-code Output

I'm new to pro/E and Creo. I am having trouble with the expert machinist output to G-Code. My Machine tool does not like the format of the post processor. I have the basic 2 ½ D CAM that comes with Creo. The post outputs the tool path in as follows: N0012X00035Y0015F01. My machine tool interprets this as X=35 and Y=15. It should be X=0.35 and Y=1.5. In addition, can I adjust how the line numbers are generated? I would like to start at N0010 and increment by tens. I cannot find in the documentation how to change these formatting issues. I have tried using the NC Post Process under the Applications menu, but I’m not sure what It is actually doing. There is only the one default profile UNCX01 under the machine setup. And the list file says its using the UNCX01.p00 file (This file does not exist on my Hard drive.) So I’m at a loss. Any help would be appreciated. Thanks

Richard,

my colleague told me that "Expert machinist" module has significant limitation - it contains only one postprocessor (hard-coded). User cannot select different postprocessor. User also cannot modify the default postprocessor.

You have to use different manufacturing package to get requested output.

Ok, after a lot of google and research on the internet I found a post to use that was writen for my machine tool. Now how do I get Expert machinist to use that post?

Hi Richard,

Judging from the NC codes posted you still need to edit your post processor. I would suggest (if you have not done so already) to go through the various tutorials and recources at PTC's GPOST central http://www.ptc.com/cs/cs_24/howto/ncgp4903/ncgp4903.htm . As for using a particular post, you can create a workcell specific for your machine. Each time you create a manufacturing file select a machine specific workcell.

Hi Martin,

Admitedly I rarely use "expert machinist" (regularily using "NC Assembly" instead), however for the purpose of the exercise I checked an existing "expert machinist" file (Creo 1.0 - M020) and was able to toggle between existing post processors (and workcells) no problem. I was also able to access "Option File Generator", in which I could create and edit post processors?

If the stand alone Creo platform (eg no manufacturing licences) has such limitations, then with the exception of training purposes, it would be of little use to anyone?

See how you get on Richard.

Cheers,
