G-Code to Geometry

[wruedawg]

I am not a regular Mastercam user but I remember a few years back when I could take G-code from another software and create geometry through the backplot command. I need to create geometry from Amada laser G-code. Could someone give me the steps on how to do this, if it's still possible?

In the backplot display menu there is a feature to create geometry from backplot. just be careful as all tool motion will be drawn. including rapid moves and rough finish passes. so you will need to edit the geometry once you have created it.

Hi dawg.

there is a post called rpfan. It is for reverse posting. I could never get it to work at all. I have read some response on the forum about it but have never heard of anyone who is actually using it.

good luck.

Billy,

 

It's just much better to start from scratch than to reverse post.

Do a search, you should find plenty of info

for using rpfan.

 

PEACE

We reverse post quite often, email me if I could help you.

James,

There are plenty of programs that have been around this place longer than me. It never fails that the machine it was programmed for is busy or has been junked or something and the job is hot. I find it is better to have anything that works rather than start from scratch.

Heeler,

do you use rpfan?

James,

Old laser programs are easier to reverse post then to start from scratch. They are mostly just XY moves with no cutter diameter. Backplot creates the geometry of the flat blank that hopefully worked in the past for the brake tooling they have or it gives you a great starting point from what you are currently producing off the laser.

this is very interesting, we have some programs made at the machine and i will like to have some geometry for it, how exactly this works please

?

thanx

You create an NCI file from the gcode. Then backplot the NCI using the create geometry feature. I see it would be very confusing on most machined parts depending on programing style. It works well for us on laser programs. Probably works good on wire edm programs too.

Stonker,

I've done everything you just said. I created an NCI file and when I went to backplot, I got an error "RP.exe not found." What now???

[richardtraver]

to get rp to work check in chooks folder and read the revpost.doc it tells you how to get it to work

[wruedawg]

I don't have a revpost.doc in my chooks folder....

[heeler]

Sorry,

 

I've been away. Yes I use the rpfan.pst. I will then backplot the file and save the geometry. You can then offset the chains the radius of the cutter to get the Part Profile.

 

Email/send me a program and I'll see if I can help you.

P.S. the name of the file is ReversePost.doc
