Another Post Help

[Kevin Goddard]

First off, I am post editing retarded. With that said, I am trying to teach myself to modify post as we are not on maintenance and will probably not update to X right away so I need to be a little more self sufficient. Our current post lacks a lot to be desired as they are V8 post and do not support a lot of stuff we should have been using years ago. I am trying to modify the MPMaster for Haas verticals. Mill level 3 V9.0 sp1. On to the first of many questions. Is it possible to output the tool diameter offset (Dxx) only once on the G43 line of an operation instead of on every cutter comp line (G02G03)? BTW, I cannot access the FTP at work due to firewall. Thanks in advance….Kevin

Just wondering why you need to get rid of the D callout? If it is a file size issue I'm not sure if it is worth getting rid of a D callout to save space. Yes it is redundant but it is there for safely. You might want to lose the line numbers and spaces to shrink the file size.

Did you try the MPHaas post. That works pretty well for most people with Hass mills. Besides the D is not a function of the G43 it's a function of the Cutter comp. And since the comp offset can be changed for every operation it makes sense to output it with the G41/G42 line. Your asking for trouble to take it out.

I understand G43 is length comp but we never use a different dia. offset than our tool# or TLO. So, when the operator needs to change the tool# in the program he simply changes the Hxx Dxx on the G43line and does not have to chase down all the Dia. offsets as there can be quite a few.

Not to jump in here but doesn't the Haas control have an edit all feature, to make just such a thing easier.

[Eric S.]

In the HAAS control there is a handy find and replace function. Great for replacing D values.

[Mike Mattera - TFM]

Why does he need to change the tool# at the machine?

This will give you just one offsett number to change and will also imput a new offset number if you choose in another operation;

code:

---

pccdia          #Cutter Compensation

#Force Dxx#

# if prv_cc_pos <> cc_pos & cc_pos, prv_tloffno = c9k #<<<<<<<<<< add the # sign at the beginning of this line

sccomp

if cc_pos, tloffno

---

This isn't exactly what you're asking for, but is much safer IMHO.

[Tim Johnson]

OK,

I've just tried the dia offset in the G43 line and it seems to work nicely. You still need to put the # sign in front of the line in pccdia as shown in the previous posting, but need to change in ptlchg_com;

 

code:

---

      pstock

pindex

sav_absinc = absinc

if wcstype > one, absinc = zero

if lock_codes = 1 & not(index) & rot_on_x, pbld, n, *sunlock, "(UNLOCK)", e

pcan1, pbld, n, *sgcode, *sgabsinc, pwcs, pfxout, pfyout,

pfcout, *speed, *spindle, pgear, strcantext, e

if lock_codes = 1 & not(index) & rot_on_x & cuttype = 0, pbld, n, *slock, "(LOCK)", e

pbld, n, "G43", *tlngno, *tloffno, pfzout, scoolant, next_tool, e #<<<<<<<<<<<<< change this line

sav_coolant = coolant

if coolant = 1, sm09 = sm09_0

if coolant = 2, sm09 = sm09_1

if coolant = 3, sm09 = sm09_2

---

If you do make a dia offset change in a different operation then the new offset number will just be where it is now.

Thank you Tim, remming out the force Dxx works great.

[Tim Johnson]

Kevin,

Did you get the dia offset code on your G43 line?

[Kevin Goddard]

Tim,

I got the dia on the G43 line by adding *tloffno in the ptlchg_com section but it started putting out some other stuff as well like block deleted G28 G90 I do not remember exactly. Since I don't know what I am doing, I will leave it alone though I appreciate your help very much.
