G95 output for tapping

[So not a Guru]

We have modified the MPROUTER.pst for our 3-axis Mazak mill. It works pretty well except that I can't figure out how to make the tapping operations output in IPR feedmode.

Can anyone get me pointed in the right direction?

I have this section:

# Feed mode G code selection
sg94    : "G94"      #UPM
sg94d   : "G94"      #DPM, See pfcalc_deg if you use another gcode
sg93    : "G93"      #Inverse
sgfeed  : ""         #Target string

fstrsel sg94 ipr_type sgfeed 3 -1

 

I tried modifying it like this:

# Feed mode G code selection
sg94    : "G94"      #UPM
sg94d   : "G94"      #DPM, See pfcalc_deg if you use another gcode
sg93    : "G93"      #Inverse
sg95    : "G95"      #UPR        #set with mi9$
sgfeed  : ""         #Target string

fstrsel sg94 ipr_type sgfeed 4 -1

 

But that gave me errors on the lines that I changed.

I am curious why you wouldn't just use the MPMaster post that's written for mill's? I am pretty sure it is already setup to do tapping in IPR..

 

If there is some reason you don't want to use the mill version.. you could probably download it and use it for a reference for the logic you need.. 

[civiceg]

use_pitch   : 0     #0 = Use feed for tapping, 1 = Use pitch for tapping
rigid_tap   : 0     #0 = Floating tap output, 1 = Rigid tap output (suppress spindle output and output M29)

Because our seat is a router seat.

I might try the mill master for reference if I can't get this working.

 

Thanks

use_pitch should do it, I had to change the opposite way. Inches per rev to inches per minute and no special mcode for rigid tappining.

I copied and pasted the entire drill section from one of our mill posts into a router post for use with an angle head.  It required a number of other edits to get it to work but it now posts without errors.  I have not had a change to cut anything with it yet but the code looks like it should work.  Its for an Okuma but it might be useful in pointing you in the right direction.  I can email it to you if you think it will help.

rigid_tap   : 0     #0 = Floating tap output, 1 = Rigid tap output (suppress spindle output and output M29)

Where do I put this at?

[civiceg]

It should be in there if its an mp master post. Its in the beginning IIRC

We're using the MPROUTER.pst, modified for our machine. Unfortunately we have Router, not Mill. We are trying to get converted over. But for the time being we just keep trying to make this work. I'm beginning to see spots

[So not a Guru]

I can't find "use_pitch" in any of the posts supplied with MC, in the Mill or Router folders.

[civiceg]

Just checked the generic Fanuc post in X8, its named slightly different and in a different location. Search for "tap" its labeled for g94/g95 as well.

[civiceg]

I don't know if the router has it, but the Fanuc 3 axis does.

This is the misc2 in my post

"pmisc2$          #Canned Misc #2 Cycle (User Option)
      pdrill$"

 

Is this refering to misc integers or misc reals?

[So not a Guru]

I have this in my post text sectton:

Can I use the same code that you posted, except using misc8?

[So not a Guru]

I have this in my Miscx Values section

"# mi9 - Unit/Rev Feed Output (G95)
#       0 = Off
#       1 = On"

 

But putting "1" in the field of a tapping op doesn't change anything as far as outputting code goes.

[Ben Wood]

I am no expert but looking at the router post I modified I think you will have to make changes in three places.  Below are the three areas with what I think needs to be changed.  I am not sure what the !feed does but it was in my post so it may or may not be needed.   If you want to control it by the misc values there will be a little more required to make it work.

[ahaslam]

Thanks. I did find a typo

prdrlrout should be prdrlout there was an extra r.

[ahaslam]

Unless that was intentional...

It wasn't intentional.  Not sure how it happened since I used copy and paste.  I went back and fixed it in case someone else tries to use it.
