My work has acquired a Colchester 220M with a Fanuc 21i-tb controller

how do I go about getting a post so i can do my operations in Fusion.

where do I even start? 

is there someone i can hire to create a post that will work with my machine?

Hi

 

You can in the first instance try the Fanuc turning post from the Fusion library.

I should have mentioned

this machine has live axial and radial tooling

so the post would need to be a MILL /TURN

A lot of people use the Doosan one but that's a 31i

Generally the first step in determining whether a post will work is having a good understanding of all the required code formatting/which G codes/M codes the machine uses, or having known good programs to compare the output to.

 

sometimes all that needed is some simple edits, other times there may be some more complicated changes required.

 

Working with an Autodesk partner is the most reliable way to get a good working post if you are not comfortable making edits yourself

OK 

I used the doosan post and it seems to be working for outputting my code ( have not tried in machine yet)

here is a sample of a live tool doing a spot drill in the end of the material

most of it makes sense to me with the exception of the M89 at the end of the drill cycle line and two lines below it

 

this section of the program  is supposed to drill two holes in the end of the part 1.25 inches across from each other

I cant see how this is drilling two holes unless the M89 is used to repeat the drill cycle at C0. since the first one is at C-180.

Hi

 

G83 is MODAL so it will perform a drilling cycle at every block with a XYZC coordinate until G80 is called

 

The M89 in this case is the C axis brake ON, M90 is C axis brake OFF

Thank you 

That clears up a lot of things

I can see myself moving forward with this using Fusion to create the program  and maybe even modifying the post to suit my needs
