LIMAC double blade post processor
« on: May 17, 2018, 11:20:27 PM »
Hi All,

 I'm looking for some assistance with G code modification to run a double knife board cutting manchine.
 One knife is straight blade, other knife is a 45 deg angled blade.
 Both knife heads rotate in order to cut in all directions.

I have configured the CAMduct software using the AXYZ post processors.

The machine suppliers provided the controller with Autocad & CAMduct & suggested the workflow was to create dxf files in CAMduct & then use Autocad to create double layered G code.

The NC files require an additional command code 'C' to rotate the 45 deg angled blade to cut 'V's for folds but the Post Processor will not generate the required command for this part of the cutting process.

 Just wondered if anyone out there could provide a solution so that CAMduct will generate G code including the C code to rotate the angled knife head?

Using Windows 10 & CAMduct 2018 - Sample NC file attached as provided by LIMAC machine supplier

Custom Post might be the best option. You should be able to define about anything you want in there.

Thanks Darren,
thats what ADSK suggested.

Being a complete virgin at creating custom posts I started to investigate & got completely lost.

Do you know if there is any way of starting with an existing post & then modifying to generate the C code I require?

It looks like a complete minefield & I'm concerned that if I get something slightly wrong I'll break the LIMAC machine!!!

I'm trying to create a 'C' code to rotate the 45 angled blade so it will cut the 45 deg groove for folding so 1st pass is '0' deg & second pass is '180' deg.
I've been told by ADSK that the blade rotation is controlled at the controller but all the sample NC files have the 'C' code within them so obviously the machine controller needs to read this to drive the head rotation.

I would expect someone out there has come across this before and requested a post to perform the operation?
