Cant get simulation to profile -X contour in Fursion360 turning

[housermp]

I have to reverse the spindle M03 to M04 and profile around the part in the -X direction. I've been able to design a tool that should work but the simulation won't work.

What am I doing wrong?
Thanks

Don't think profiling on the -X is possible at this moment.
Are you able to get any toolpath to generate?

[housermp]

Yes the + direction tool paths generate.  Unfortunately I need G Code generated with -X values.

Also, it would be useful to create a tool path by sketching a simple entity--a line for example and use that as a tool path.

I can use Cimco Edit to reverse the X sign as a work-around in the time being.

Do you always run on the -X side or just occasionally?

[housermp]

I frequently use "multi-tools" for ID boring/plunging then reverse the spindle to machine the OD with the same tool.  Both ID and OD cuts with the same tool can be roughing or finish profiling operations--both require back turning (undercutting) on occasion.

Jeff,

Something to write up as an enhancement request?

It’s been written up a couple of time in the past but I just added another ticket CAM-2468

Hero! 8)

Hey thanks for writing this up.  In production, this feature makes efficient use of tooling.  We're currently using Mastercam and Cimco edit however, the Fusion platform looks really promising going forward.  At some point, as turning cam flushes out a bit with features, we'll make the switch.

If you want to delve into it, look for a thread on gang tool lathes by Tactical Keychains, we went through a few different options and eventually implemented something to accomplish this. It was pretty hacked together, but still seems to be working well for him.

My part off tool works in the - direction, post attached.

Tacticalkeychains,  many thanks for the post.  I think I'm going to wait until the simulation is incorporated into Fusion360 turning cam.  I do this +/- X turning on several machines each of which has its own coordinate system.  Having the simulation helps avoid the nasty tool crunch.

What you could do is incorporate it in the post and then use the Backplot in the Editor to verify the toolpaths. I know it's not a true simulation but it get close.

I thought about that but I suppose a different post Is needed for each machine and I have no experience with js. Would the same patch work in each post?  What settings in the tool menu would trigger the correct output?

That all depends on how different your machines are.
But since it would just be flipping the sign of the X, there would be 2 places something would need to be done.
You flip the X in 1 place and change flip around G2/G3, since exactly the other one would be needed.
You could for example use the manual tool change check box as the trigger.

Laurens, I'm interested in trying it.  I'm using the General Fanuc post. I'm thinking this can be adapted/saved for the other machines.  I'll need a bit of help to get started.- thanks!

Alright,
do you machine have live tooling? Y-axis?

[housermp]

only one machine has live tooling and C axis-- no Y.  The other machines are "plain vanilla" 2 axis.

Hi,  can you give me an idea where I would make the edits in the post?
-thanks.
