Mirroring with offset G41

[MAXKUM]

Hi All,


I just noticed that when you mirror any program in Y axis the post doen't change G41 into G42 automatically. The climb milling changed to coonventional but offset type remain same. You have to change manually. Why??Does any one has faced the same problem.?? I thought Pro/E works with LOGIC.

Hi

Hope you are doing trajectory milling

Hello,


Can you expand on this subject. I am programming some 3-d style motorcycle rims and am going to mirror the toolpath. I have just switched over from Mcam to ProNC. What is the best method to reproduce the mirror toolpath?

PTC has some material available for this and other new topics in WF3. I think it is open to all. I believe the process is to send an email to Francois Lamy ([email protected]) requesting access to the Advanced Mfg projectlink project.

There, you'll find quite a bit of info regarding what's new in WF3, as well as other tips & tricks. Note that not all of the info pertains to WF3, but Pro/NC in general. I mention the WF3 aspect, as the mirroring of sequences is new in that version.

Hope that helps-

(Apologies to Francois if you get hit with a ton of email requests, or if this is not appropriate...)

What version of ProE are you running? WF3 has (finally!!!!) MIRROR capability, where it changes cut directions to keep it in CLIMB mode, keeps Lead-In's and Out's on the correct side, etc. There's few glitches to keep eye on, but in most cases it works really nice.
Search this forum for MIRROR, there's more on that there.

YamahaRobb,


You do not need to mirror your tool path, you need to do a pattern. Will you be doing this in the part or in the mfg file? I would mirror the part. This should make tool path work better. MAXKUM, can you post this tool path?

I will be doing the toolpath in WF2. CNCWiz you are saying that I should just mirror the part andwrite the same tool path again ? Or is there a way to mirror the part with the tool path intact, like doing doing a miorror in an assembly to create a new mirrored part. Instaed I will create a mirror in a mfg file to create a new mirrored mfg .

Robb,


If you do a "pattern" in the part, it will work alot better. You can pattern by "axis" and add all the spokes or whatever you want. All you have to do with pattern number of times you want to pattern it and what degree. As far as this mirror issue, I dno't think that the "G41" will ever work. This is turned on to cutcomp "left" on one side and cutcomp "right" on the other side. One side the tool will move one way and the other side will move the other direction?

Thanks CNCWhiz.


I have done the patetrn on the spokes, but looking for a quicker way to mirroe the toolpath. I will keep investigating.

I would not use the mirror. I only use mirror in the sketch mode.

I use "mirror nc sequence" under utilities and have no problem with it. I still have climb cut and correct cutter comp output. I use it every time when I need a left hand part. Any changes to the right hand part will automatically updated for the left hand part.
