5axis Zlevel cutter comp - tech question

Solution Partner Phenom Solution Partner Phenom

Hello,

 

Ive checked the cutcom dialog in 5axis zlevel.

It looks like 2D cutcom.

Shouldnt be there 3D cutcom? - In case of tilting.

In case of no tilting, agree, could be 2D cutcom.

 

Or am I missing something?

Example for 5axis zlevel with tilting, variable tool axis path.

thank you and have a nice day

There's no OOTB way to specify what type of cutter comp to use.

I generally have a UDE to the effect of "cutter comp type" where user can specify

- 2D

- 3D Swarf cutcom

- 3D "ball" cutcom (generally requires contact output)

- All those Siemens 840D variants

 

In theory you can check mom_operation_type, mom_tool_axis_??, and whether contact output is on, to set a default cutcom type.

(In particullar  - I am looking at my heidenahin PP.)

 

- 2D cutcom (RL/RL) -  planar, cavity,zlevel..planar based tool path.

- 3D cutcom - (contact vector NXNYNZ with LN, eventually TXTYTZ.) - fixed contour, variable contour.

So I asumed 3D cutcom like in variable contour should be here in "5axis zlevel".

That why I am asking.

 

And then if you have not contact vector it is not possible to output 3D cutcom (NXNYNZ).

And to use 2D cutcom in 5axis simultaneous - I cant imagine.

I hope that it is clear.

 

Or do I need som other nc output of 3D cutcom  which doesnt need contact vector?

Because I thin there is possibility:

M128

L XYZ ABC RR/RL

Not sure how it works.

 

Dont want to complicate it.

But it  is strange to me. I need some example or advice what to do with it.

(Can somebody show me nc output of 5axis zlevel with that 2D cutcom on or if it works correct?)
