Cam Turning a groove

[Anonymous]

Hello

We are currently evaluating the fusion 360 software for use in our CNC production facility, we dont have much call for cam at present as existing packages are expensive, and fusion 360 is looking very attractive.

We do alot of grooving on out lathes and was experimenting with using the grooving function on this software.

I have drawn a simple model with a sqaure grooved machined into the diameter, When i simulate the tool path the grooving tool comes in and roughs out the groove, then goes into a finishing pass which is fine for the plunge in and Z- direction, but when it come to the final cut out on x the tool is trying to remove approx 1mm using the side face and retracting tru the material, We would plunge down both sides then do the finish pass along Z, is there a option to select the order the faces get finished, or how much material to leave for the finish pass?

Regards

Peter

post the file you are working on, past a link here or export it out from A360 and attach it, and say what post you are useing. it would be easier for you to get support this way unless it's under NDA

Take a look at Up\Down Direction, you want Only Down.

Edit just run the simulation with the setting above and the toolpath is not what it shows above. It doesn't even finish this face and does a nasty undercut! File's attached.

I missed the second part of your question about the amount of material left for finishing, see below.

OK figured it out, it works correctly if you have no confinement, looks like a bug if you need to only machine a small area though.

This is how I had confinement selected in my first file.

File attached with confinement off.

I couldn't leave alone until I got this working. You can use confinement but you need a small front and back offset for it to finish the sides correctly. Sorry for all the posts but there's a lesson in them!

I have reported this on ticket CAM-4049. You shouldn’t have to extend the confinement to get the tool to cut fully
