Hi all:

Could anybody please help me to get some material for learning GPOST

Leow,



Learning GPOST on your own is a major undertaking. It probably will not
happen but you should go to Austin, TX, USA and take the Post Processor course.


You can go on WWW.AUSTINNC.COM and order the manuals. I would suggest
you order 3 manuals, APT, FIL & GPOST.


In order to be successful you should have a total understanding of:


1: The machine tool/controller codes that are required to machine
your parts.


2: You need to know how a CL file works. You need to know its
construction and how to parse it and what each record variations are.


3: You need a good understanding of computer language programming,
preferably FORTRAN.


4: It would help greatly if you new the APT programming language
since the FIL (Factory Interface Language) programming is very
similiar and APT statements can be used in the FIL file.


5: If you can obtain a FIL file and decipher it and understand
each and every line, this would be a good start. There are
many things that are either not documented/or not very obvious
as to how the function.


Build yourself a test model/program that addresses all the functions
you will need in the post to control your machine. Keep it simple.
If you can drill 2 holes, 100 holes does not help. Then understand
how these functions are represented in the CL file. The CL file
is the "bridge" between ProE & GPOST. You DO NOT want to have to
edit the CL file to get your results.





It would help if you had a knowlegable person to ask questions in your time


zone. I have been doing this for 15 years.

I hope this helps.

good starting point is

It says this file no longer exists.

Hmmmm...
It worked for me. I was able to save a copy locally, too. I just cliked on the link in wsylvester's reply.
Not sure why. I don't think I have any special de-coder ring, or anything, either.
Maybe try it again?

Don , Not quite sure why you can't access the file


there are some others too. Some you need maintence with others you don't

I think Singapore to Austin,Tx. might not be aoption for Leow , just guessing tho.


But Austin certainly is a pretty town, I haven't been there in 30 years, then again I've never been to Singapore

I reentered the web site and it worked. There are some errors on page 8 for the POSTF for word 5, 6, 7 & 8.

There are some errors on page 8 for the POSTF for word 5, 6, 7 & 8.


would you mind sharing what those errors are so the users in this forum will know what they are





thanks

Try this.


ALIAS /%FCL5,POSTF(7,4) $$4 should be 8 POSTF(7,8)
ALIAS /%FCL6,POSTF(7,4) $$4 should be 9
