Post-processing question - canned roughing cycles (turning)

[jodyF8L9L]

Hello,

I have a post processing question. I am trying to use canned cycles for turning roughing operations. However, I want the ability to have the post processor ignore the canned cycle and treat as normal linear passes. The reason for this is some of the VTLs I am programming for cannot deal with/interpret canned cycles, and some can and is even preferred when using those machines. So, I would like to create roughing operations always using canned cycles and simply have the ability to ignore when posting for machines that cannot use canned cycles. Is this possible from a post processing stand point, or do I need to adjust roughing operations when canned cycles are preferred?

Thank you!

If you try to post-process an operation that you have set to use a canned cycle in Fusion, with a post-processor that doesn't support the canned cycle, it throws an error. So I do think you have to control this in the operation, and it's not possible to easily change it at posting time.

@Laurens-3DTechDraw yes, the way post-processors are setup is a simple if canned cycle supported then write certain gcode, else throw error. But my question is about restructuring to be more like if canned cycle supported, write g68/69/72 etc, else loop back to linear/circular movement function and write g1,g2,g3 etc.

That's exactly what I'm trying to say, the post processor doesn't get the information for G1/G2/G3 movements when you select use canned cycle in Fusion, so you can't make it switch.
For the drilling cycles, it's always sent as the canned cycle information to the post processor, and there the Post kernel remaps that to G1/G2/G3 moves if your machine doesn't support a certian cycle. You can also do this yourself, but that will require some serious coding to implement canned turning cycles.

@Laurens-3DTechDraw thanks and that's kinda what I was afraid of - more coding than what it's worth - but was hoping that someone somewhere had a similar problem with a solution. I created a macro/add-in that will switch all rough turning ops to/from canned cycles pre-post process, so, maybe that's about as far as I want to take this as far as coding goes. And I will work more with the machinists/machines to see if canned cycles can be universally implemented, too.
