round up of xyz tolerances to 0.005 mm

[ngkim]

i wonder anybody knows how to round up the values of x,y,z to 0.005mm during postprocess.any suggestions will be greatly appreciated.

[Michael Reynolds]

I think you go into screen, config, then tolerances & change the settings there.

or...screen, config, NC settings, and change the "number of places after decimal point for NCI files.

Hope this helps!

Cadcam,

I teach precision machining I & II, CNC machining, basic fixture design, CNC mill programming, CNC lathe programing, Mastercam I, and Unigraphics Cam. Noticed which one came LAST?

C-ya!

Mike,

Hello fellow teacher. I teach Mastercam at a local NTMA Training Center http://www.trainingcenters.org 2 nights a week at the Inland Empire Training Center. I thoroughly enjoy teaching, it's my way of giving back to an industry that has been good to me. NOt that it hasn't had it's ups and downs, but for the most part, it's been up.

James,

If I sent you my syllabus for the mastercam course, would you look it over and tell me whether or not I'm on the right track? I'ts a brand new class (I've been teaching it in the cnc machining/fixture design classes, and I just got a stand alone mcam class approved to run this fall.

I'd really appreciate it!

thanks!

Back to the original question, if all else fails, you can always do the following to round to the nearest .005 mm:

1. Set decimal precision to 3 places. I think 2 is the default for metric.

2. Multiply: x * 1000.

3. Add .5

4. Divide by 1000.

I think you can do this in the post.

i tried all that(screen-configure-nc settings) but i still get readings after posting liked Y 39.072,X-134.208 which is ridiculous for the machine to read.what i mean is round them to 0.005 mm.i wonder how to change settings as suggested by Mr. Dave Eno in the post??

Mike,

I'd be happy to look at your curriculum. Maybe we can swap Projects. I've got a few pretty nice Advanced Projects and Beginning Projects.

The XYZ value output format is controled by

Format statements:"fs2 2 0.4 0.3" in mpfan.pst of V8

You just change to "fs2 2 0.45 0.35".The last-variable rounding will output that you want.

thanks a lot cam-home,you are an expert,now it really post to +-0.005!.you are a great teacher!

Kudos to all you teachers out there! I am an instructor for CNC/CAD/CAM also, and really enjoy it! It's nice to see so many teachers that have actual hands-on experience, as opposed to the ones that only read about what we do and then try to teach it.

[Michael Reynolds]

Hey Rekd, you're absolutely right. It's really frustrating.

I've yapped too much...

C-ya,
