How to include tolance in APT file 1

[snowfire]

Hi, How is everyone?

I have a question from my friend which I don't know how to answer. I post it here wish some one can help my friend.

He defined a workpiece for his machining part and generated program for that part.

He wants to know how to include the workpiece (together with machining coordinate system) and tool path tolerance (defined in profile machining tab, value is 0.001mm) into APT file.

I don't know if I made myself clear.

Wish you guys can give me some suggestions.

Thank you

Sorry, The topic should be " how to include tolerance and workpiece in an APT file.

with a print apt command its just a command line so.......

 

[klaas2]

print /text
This statement allows the programmer comments to appear in the postprocessor List File. The slash
character (/) is optional and, if not programmed, must begin in line column one.
text is the characters from column 7 through 72 of the input statement, which is printed.

Thanks Klaas2, so nice to have your reply.

But I am still confused. Could you please give me an example.

My friend wants the tolerance appear in APT file automatically.

I have had a look in the NC infrastructure file.

Do you mean that I can use pprint command in post processor?

Can I change the post processor?

I have found "PPRINT OPERATION NAME = %MFG_MO_IDENTIFIER"

Can I change it to be the tolerance?

Thank you so much!!!!!

can you give me a example how he wants that wich tolarance becuase there so many differant one
and how does he do the tolarance now
and in wich program is the apt code generated?
to wich post processor ~? machine? tool?

print is taken in the postprocessor
but of course that depands of you post processor
if you have a tool to program a post processor you can do it your selve to take the apt command and generate the appropiate iso code
example
but general print/ tol ±0,002
is taken in the iso code as ascii text

the same is
print/ the machinist is a special guy

N0010 G54
N0020 G01 X100.000 Y50.000 10.000
N0030 the machinist is a special guy
N0040 X200.000 Y60.000

Thank you so much.

He did a profile program in CATIA. He post it as an APT file so that he can post-process it with a 'out side CATIA' post-processor.

He wants CATIA automatically add the tolerance defined in CATIA program to the generated APT file.

same as the workpiece, he wants CATIA add workpiece information automatically into the APT file, not the final NC file.

Hope I made the problem clear.

so in what module did he made the tolerance surely not in nc programming
he must make a macro with a machine in struction to put the statement and to run this macro he can dedine this under a key wich he choose him selve

 

[klaas2]

well i generated a machine tolerance with circulair milling

and the date that you define there with machine tolarance
i have made it 0,05

is as shown here the intol/ parameter 0.05
