Rotary Help

[xycnc]

HELP!!! I am new to programing on 4th axis programing and I need to do this Job. Any help or ideas would be great I really think its not a hard job, I just need pointed in right direction. It is going to be done on a Mazak with a rotary in the X axis. It is the cam action that I am needing help with. Thank you

I would use Curve 5 axis with a 4 axis output.

 

Create a curve at the centre of the radius, use that to drive the tool

Thanks greg for your quick response what create curve should I use to get it in the center of radius?

Ok new question... I just talked the designer and he said that inventor doesn't draw the cam model correctly. Can anyone maybe help me out to try and get it drawn right? Part rotates 90 degs over a 2 in spread. maybe Im fighting a lost cause here but looking for any help. Maybe I should just try it in Mazatol instead, but I'm trying to learn something also Thanks again

How about this? This really looks like a case where Rolldie is your friend

JParis this looks like what I wanted. Now If you could help me by explaining how you got there? I found rolldie under Chooks but just how you went about creating Geometry. Thank you for your help I really appreciate it. Also am I correct in that I will have to take the toolpath you gave me and then just using 4 axis sub is X?

Thanks again so much

Ok after messing around a little more I think I kinda figured out what you did. You picked the outside of the slot and then unrolled that geometry. Then you offset that geometry by half to give you a centerline. Then rolled that around to .875 to get your geometry in center. Then used the c-hook roll die. Am I close?

You got it

 

Unrolled, create center line, roll it back up, use rolldie

 

Also am I correct in that I will have to take the toolpath you gave me and then just using 4 axis sub is X?

 

4 axis sub?

 

The Rolldie will create that motion as an Axis Substitution motion, there will be XZA motion because the A will get substituted for the Y So you'll get no Y motion

 

I "think" that was what you were asking

thank you for your help. I got the part done and they were pleased.
