4.5 axis?

[crabbass]

Does anyone here use there 4th axis rotary table mounted on a 45deg. angle?

No, why do you do that?

[crabbass]

I saw this option on featurecam or mastercams website. They advertised their new version being able to post code for simultaneous 4 axis on a 45deg plane.

5 axis cadcam ?
i used to use a rotary that was fixed on a sin plate , quite handy under the right circumstances

What is it that your trying to machine???

[crabbass]

I thought about the possibility of using a sine plate .This would be handy for gear hobbing. (sine angle would be set to cutters pitch angle. cutting would be in the x and z direction. I havent tried it, but I think multiple passes would be difficult to controll accurately.

tobyaxis,
I am not looking in to doing this. If I had a blade or blisk to machine I would use a trunion 5th axis. I was just curious if this 4.5axis scenario was being used by anyone with success.

Anything is possible. Just be safe about it.

OF COURSE!!! Mount it any angle you want (if it makes sense for the job)! I have often had to get creative with the angle that I mount the Rotary table. Makes things more interesting, also.

In theory it is a Perpendicular Face Plate.

Here is a picture of my 4th axis mounted on an fixed for quick setup angle table, its a VF2.
I use it every day, and works perfect for rough and finish, it is a must for the kind of job we do.
