5 axis help! Wanting to lock out an axis from moving

[Silver3369]

Hey everybody,

I apologize I am unable to give any pictures or anything of what I am working on.

 

To put it simply I have The inside of a bowl that I am trying to cut with a ball mill and I need a good finish through out the bowl. So I want to tilt my A axis and keep the tool stationary and let C rotate to cut my bowl.

 

i have gotten the geodesic tool path in triangular mesh to give me what I want, but when I post it out it has x and y movements. So how can I eliminate the movements that I shouldn’t need. Any help or a point in the direction of a better tool path would be greatly appreciated. 
 

thank you

Can you output it as 4+1 

 

Or you may be able to convert a scalop or waterline surface to 5 axis and lock A where you want it

Unless I am misunderstanding greatly here.  As long as you have a dead simple pattern surface (centered on the c axis, probably spherical in this case), all you should need to do is use fixed angle to axis in the tool axis controls.  Set the tilt angle and the axis to "tilt" about.  If those don't work, use the maintain tilt checkbox, set conical limits, or possibly adjust your pattern surface.  May ways to skin this cat.

 

 

Now that I have read the post and possibly understood what is being asked....   I am guessing you have an issue with the pattern surface.  Try using parallel instead of geodesic.  Shouldn't make too much difference.  Also, make a simpler pattern surface if you can and see if it does what you want, then introduce new variables as needed to get the output you want.
