mplmaster edit question (mori nl2000)

[neurosis]

My question is where the G112 and G113 output are concerned.

 

When we ( I am helping out lathe area out with the lathe post ) program a c-axis profile, it seems that the lead in and lead out are read before and after the pmillccb and pmillcca.

 

The issue that I am having, is when it alarms out on the G113 I assume because it needs to be turned off after the cutter comp is canceled. I was getting an alarm at the G112 also but I muttled my way in to something that worked although I doubt it is correct.

 

Can someone help me understand how to get the G112 to post before the lead in, and the G113 to post after the lead out move? I tried to remove the lead out move all together and manually drive a lead in and out but it will not turn the cutter comp on or off properly unless I use the leadin/leadout.

 

This is the latest version of mplmaster downloaded from this site.

 

Im not very familiar with our lathes so try to bear with me. There may be some rules to c-axis that I dont understand so feel free to correct my ignorance.

 

Thanks.

Yes, the control needs to read the G40 before the G113. I usually manually create the lead-in and lead-out, but it seems I have done it the other way also. I am not at work so I can't see if my post will turn cutter comp on correctly doing this.

 

Try using the cview utility and the regular mill contour toolpath instead of the C axis face contour toolpath. I usually have better luck with these, and I would try to see if lead-in will work with this one. It seems to me that I have used lead-in and lead-out page with success, but I can't remember off hand.

Neurosis,

Are you using the latest version of MplMaster? I did a C axis face contour and this is the code as posted.

It's simple straight cut with a 1/2 endmill, comp in wear, I've set misc value #4 to ON, I'm using lead in/out.

 

I did some digging in the post and based on the output you're showing it looks as if someone has edited the order of events in the ptoolend$ postblock. Check the order of pmillcca, it should be read prior to pm_retract

[neurosis]

cj,

 

Are you using the leadin/leadout? I can get code similar to that but the part that we are profiling does not have any straight cuts. It is all radius. I am using the lead in and lead out to turn on and off the cutter comp. If i remove the lead in and lead out. Maybe I should just add a straight line at the end of the profile for the lead out to turn off the cutter comp?

[CJep]

^^ yes I'm using lead in/out but I've also extended the geom that I'm using for the chain.

 

Is there any way that you could add a straight line move to the geom you're using?

[CJep]

Neurosis,

This is the code I get using three arcs, no straight lines, no lead in/out in toolpath parameters, comp set to wear.

Did you say that the post you're using has been edited? Was it worked on by someone at the shop or by a reseller?

If it was edited by the reseller they should fix it for you, or if it was a third party post the reseller should contact the post developer for you and get it corrected.

If it was edited by someone inside your shop well,....

 

 

sorry about that previous post I didn't read and completely process what you had written before I hit "Add Reply" (I've only had one cup of coffee)

My NL post works with lead-in and lead-out using G112 in both C-Axis Face contour and Mill Contour.

I would prefer to blame it on the shop "hey boy" java script:void(0)

 

that code looks a bit more like it

be careful with that coffee I think I had one too many now I'm railin' or was that the espresso
