PECK DRILL CODE LONG HAND

[HEAVY METAL]

Belwo is a code for long hand peck cycle because control does not have canned peck. below that is my post language. What my problem is the z is not rapiding down with in .02 of last peck depth it is starting from top plane after every peck and feeding to next z depth.

 

i need after line n0004 a z value of -1800 (.02 above previous peck)I just cant seem to come up with right code. i'm i lookin in the right place.

 

thanks heavy

if mi2 > 0, pcan1, sn, sgcode, zr, strcantext, e

Are you sure your machine doesnt have canned cycles? G80 turns off the canned cycle. That would return it to Z0

[specprogrammer]

my machine would be G83 Z(final depth)R(peck)F(feed)next line G80

[Mike Mattera - TFM]

Do you have values in all of the peck parameters? The peck - subsequent peck - clearance ? If those have the right values Mastercam should be doing it with the proper clearance on multiple Z moves.

THIS CONTROL G79 IS LINEAR MILL

[crazy^millman]

Heavy you need ot put up more of the drilling block to really help you that only controls a little of the drilling cycle for the post. Here is what it looks like from the MP5GENX post:

code:

---

prdrlout        #Output drill position

psign_ang_out

if plane_2 = zero, #XY

[

if gcode = 81,

[

result = force(drlz, drlz)

result = force(refhtoutz, refhtoutz)

]

xout, yout, drlz, p_out, s_out, refhtoutz

]

else,

[

if plane_2 = one, #YZ

[

if gcode = 81,

[

result = force(drlx, drlx)

result = force(refhtoutx, refhtoutx)

]

drlx, yout, zout, p_out, s_out, refhtoutx

]

else, #XZ

[

if gcode = 81,

[

result = force(drly, drly)

result = force(refhtouty, refhtouty)

]

xout, drly, zout, p_out, s_out, refhtouty

]

]

!refhtoutx, !refhtouty, !refhtoutz, !drlx, !drly, !drlz

 

pdrill #Canned Drill Cycle

pdrlcommonb

pcan1, pbld, n, *sgdrill, sgabsinc, *sgdrlref, prdrlout,

dwell, *feed, strctxt, e

pcom_movea

This is the section that controls the drilling the pzrapid only has something to do with postion moves between parts of the operations and also repeative cycles doing mostly with milling if I am correct in my thinking. Put of this part of your psot and we can tune it better.

 

One mroe thing turn on Debug and put up the results that for the code you just put that will be a big help also.

Millman I'll give that a try

 

thanks heavy

MILLMAN IS THAT CODE FOR A CANN DRILL CYCLE

[Roger Martin from CNC Software]

if you can turn OFF canned pecking this way ->

 

usecanpeck : no #Use canned cycle for Peck

 

and program a peck cycle. The canned drilling postblocks DO NOT GET CALLED. Which is what you want! MP will now produce the drilling motions with calls to PRAPID and PLIN. I'd insert some diagnostics in those posblocks (be sure to turn off 'fastmode'). That way you can see when those postblocks get called and what is the 'Z' value they are getting.

 

code:

---

prapid          #Output to NC of linear movement - rapid               

"*PRAPID* and Z = ", ~z, e # diagnostic

THANKS rOGER STILL HAVING AT IT

[cadcam]

Roger does Paul work in the same room as you?

[crazy^millman]

Well cool beans I stand corrected. Nice diasgonsitc tool you just put up. Hum let me see page 222 in book just got an addition to it.

 

 

Sorry Heavy I was pointing you in the worng direction. All is good though like it when I learn something. Thanks for the response Roger.

Which Paul?

I assume you mean Paul D.

NO! We try to not even let him up here to the 2nd floor.

 

I'm not a member of the Post Dept.

But if I see someone (Millman^Crazy ) leading someone down the path to aggravation, I'll jump in on Post questions.

[crazy^millman]

Thanks I like atleast putting up some response right or wrong that way if I am wrong the people in the know will correct me and I get to learn something in the process. The path of education is filled with it aggravations and is how we learn in life and become better at those things in life.

 

 

I honestly try to help not hinder and my only question is why did it take a wrong answer to get you involved?

Knowing Paul D, I can relate to your situation. Keep him in the basement where he belongs. J/K Paul!
