3D CHAMFER

[paulfell]

I have milled cam edge using 5axis swarf (worked well)- trying to deburr inner edge (see picture- black lines)  

 

using 3D chamfer with a ballnose - the second picture shows the deburr is not even - the problem is less pronounced if i use a smaller ballnose - but still there.

 

Is there a way i can get an even chamfer/ deburr on this edge using 3D chamfer toolpath ??

 

Alternatively- is there  a way i can use a 5axis cycle to deburr the edge ( I know i could use swarf to mill edge if there is a chamfer on model

(i.e. deburr edge - but struggled trying to get a chamfer on model edge)

 

Any suggestions ??

 

( I have enclosed screenshots as files - is there a way i can put pic in this area - or is this for text only)

i now realise pics go on once posted - can you control how large they appear on screen ?? ( a bit small at the moment)

Clicking the images makes them bigger.

The 3d chamfer tool path doesn't calculate the vector of the tool. You will get better results going with a smaller diameter tool, or using a surfacing tool path.

As far as I know, there is no toolpath routine that will mill a consistent chamfer on a shape like you have shown.  I would build the toolpath the old-fashioned way, and nail it every time.

Create a surface of the chamfer you want, then create a surface blend toolpath, pick the inside and outside edge curves of the surface as your chains and , voila, accurate chamfer.

 

Or, use center compensation for the tool.  Then just offset geo at a 45 degree vector by the amount less than the radius of the tool that you want to cut it with.  This will work on most shapes.

If you have curve 5 axis you can do that 3d chamfer pretty well. Set the output to 3 axis
