MPLOkuma.pst and G87 LAP cycle

[Mick]

Hi there,

 

I've been trialling MPLOKUMA.PST, so see how its LAP cycle output works. Whilst it looks like the format is pretty close to what I want, I can't get it to generate a G87 LAP finishing cycle at all. Even though I choose Canned Finishing as the toolpath, it doesn't output it.

Is anybody here successfully using it?

I'm running it in V9.1MR0304.

 

Cheers,

Mick,

Is this what you are looking for?

If you are using the "CANNED CYCLES" in Mastercam V9, you may have a small glitch when trying to use a canned lap rough and canned finish cycle. It is especially a problem if you choose the highlighted tool path on the second paramter page.

 

If you use a different tool for the finish, the post will sometimes throw the code for the finish cycle to a spot in the program that is after the M2 command. It was a real challenge to figure out what was happening.

 

If this has happened to anyone, just don't use the "canned finish". Choose a normal finish and rechain. It works like it should then.

[Mick]

Hmm...Well, mine doesn't output the G87 at all. It is indeed when I select the highlighted toolpath on the second parameter page. This post is potentially great, but it would be nice to be able to output it. Why would it work for some, and not for others (ugh, I know...software... )

Anyway, I'd like to get to the bottom of it. I also note that the post supports G82 (facing). Has anyone generated the G82 using the canned cycles?

[crazy^millman]

You by chance do not have to use Misc to make these cycles work correct?

[Mick]

Heya Ron,

 

Thats correct. You dont have to set the Misc Reals etc (as in the old MPLOSP posts)

These new ones, using the Canned cycles, look to have the makings of great output for the OSP controls. I think (at least for my needs) they need a bit of refining )

The new MPLOKUMA is a pretty good post but it does require SOME tweaking to get the clean code that I like personally. The post will output G82 but it doubles the DOC for this cycle just like it does for the G81 [since DOC is diametric in the Okuma]. This is a [hack] mod that I made for this:

 

# --------------------------------------------------------------------------

# Lathe canned cycle output

# --------------------------------------------------------------------------

pg85 #Output G85 Bar Turning Cycle block

if gcodecc = 2, depthcc = depthcc * .5 # Modified for correct facing DOC (cdm)

pbld, n, *scclgcode, *fcc_NAT, *xstckcc, *zstckcc, *depthcc, pffr, e

 

 

I haven't tested this in every possible situation but it seems to work OK

Bump for Mick's crazy time zone

[DavidB]

You can only do a Canned finish toolpath if the tool nose radius is the same as the roughing tool.Its a pain.

 

 

[Mick]

Chris,

 

Hehehehe....Yes, we downunders do have a crazy time zone. Thing is, we're in the right time, and you guys are lagging....hehehehehhee

 

DavidB: Thats true...They both need to have the same nose radius. But either way, I can make the post generate a G87 :/

The post is very close to the way I'd like to be able to output the LAP cycles. I really want a foolproof system for the guys at work :/

 

Cheers

Did you check out my edit?

 

Remember to change the DOC to output 'D' instead of 'U' BTW...

[Mick]

Chris,

 

Yes, I did try the edit. It worked sweet. The bummer is, I still can't get it to generate a G87 :/

Why would it work for some MC installations, and not others? Is it the MP.DLL version?

Sorry about the delay in replying....I've been really busy :/

 

Cheers

[chris m]

I did have a .dll problem with canned cycles awhile back; different than yours but that might be it
