Hi all
I have never used the chamfer feature until now, and I am in need of some help.

The tool is a 5/16 90 degree chamfer 4 flute chamfer bit. What I am unsure about is how to tell bobcad what to do. i remember in Sorin's class he showed us how but can not remember.

Say I want to put a .030 chamfer on the edges of a rectangle. what information do I put in the boxes in bobcad to get that?

Thanks
Walt

put .312 tool in data base
draw a 2 in rectangle
make this your stock
do a contour so you can climb mill the od
pattern offset left
parrameters chamfer length .030
select sharp tool, angle 90 deg.
cutter position of .030 so the sharp tip is not cutting
then go to tool cham mill
manual select your .312 tool
anytime you make a change any where go back to parameters page and make sure
your depths or lengths are still the same i use this for corner round also

The one thing I wish it would allow is a way to step into the chamfer. I have a couple of parts that I am making that require a full 45 degree face that is .174. I want to do a "Rough" chamfer then come back around with a finish chamfer but it looks like the only way to do it is add 2 ops in the tree.

To do a chamfer without two operations in the cam tree just choose profile and setup your tool as needed dia. chamf. angle...etc..
Then choose under param multiple steps total depth .174 number of passes 2
This is what I came up with when I made a chamf tool and on a random rectangle made a .174 deep chamfer with 2 passes using the profile feature.
Hope this helps you some ..Good Luck~!:cheers:
