G300 POSTING

[COREY@SSI]

This is my first time editing a post with x3

im starting to use master cam on my tsugami swiss machine and have been doing chop and paste with the code and now im interested in getting my post working correctly

im using the generic fanuc 4x post that came on the disc and i have my program head mostly configured excep for one line

 

my program head looks like this

 

%

O3031(CHECK VALVE)

M91

/M61

 

M93032

 

N10(START UP)

M501

G00G18G99T0/M08

G300X-0.08Z1.256T0800 g300 is my problem

G150Z-0.008

M10

G00X5.4331Z-0.04T0

M502

 

 

g300 sets the stroke of the machine so the main collet doesnt hit the guide bushing

 

my plan was to use the stock length in stock setup to set the part lenght then add .580 to it in the post

 

i havent gotten to the math part yet but i did finally get the post to output the part length with a little extra junk attached

Lets assume you want the variable stck_ht$ to output as a "Z" and have 4 decimal places.

 

Add a line to format the variable.

 

code:

---

fmt  T  4   t$          #Tool No

fmt T 4 first_tool$ #First Tool Used

fmt T 4 next_tool$ #Next Tool Used

fmt D 4 tloffno$ #Diameter Offset No

fmt H 4 tlngno$ #Length Offset No

fmt G 4 g_wcs #WCS G address

fmt P 4 p_wcs #WCS P address

fmt S 4 speed #Spindle Speed

fmt M 4 gear #Gear range

fmt Z 12 stck_ht$ #Stock height for G300 line

---

The 12 refers to the fs2 statement numbered 12 describing a 4 place decimal.

 

Now stck_ht$ will output as a "Z".

 

You can now change this line:

 

"G300X-0.08","Z",*stck_ht$,"T0800"e$

 

To:

 

"G300X-0.08",*stck_ht$,"T0800"e$

 

You should get the output you're looking for now.

that worked perfectly and set me down the road to making my other changes.

 

thank you very much

[Rob @ Target Machine]

Anytime, no problem. That's what we're here for.

 

Welcome to the forum.

 

If you're interested in learning the MP language, ask your reseller for a copy of the v9 Post Reference Guide. No charge in most cases.

[COREY@SSI]

i emailed my contact at my reseller to get the guide but i have another question

 

lets say i want to add a value to the stock_ht value

 

i use it in 2 places

the first in the g300 line where i need to add 1/2 an inch

 

the second is my partoff/transfer

i want to add .01 just so i have shock to clean up.

 

ive been scrolling thru the post trying to find the formatting to add to the value but im coming up dry

[Roger Martin from CNC Software]

Instead of altering the value in pre-defined variable stck_ht$ I would suggest decalring your own variable and then assign the desired value (stck_ht$ + value) to your user-defined variable.

 

Where Mastercam Guru shows formatting stck_ht$ do this instead ->

 

fmt Z 12 g300value #Stock height for G300 line

 

Now in the postblock(s) where you need to output ...

 

g300value = stck_ht$ + 0.5

"G300X-0.08", *g300value, "T0800", e$

[COREY@SSI]

That worked really well,now my transfer is done as simple as doing the stock setup i've got my post refrence cd on the way now im working on seting up the milling.

thank you very much roger and Mastercam Guru
