Surfacing with a disc shaped tool

Hi guys I'm trying to surface some horizontal ribs with an Iscar grooving cutter inside of a cylinder. Can anyone guide me on how to do so? Thanks.

define the tool . then you should use 2.5 axes closed contour procedure .
you can pm me for more info

Thanks for the reply. The problem was in the tool definition. I did not specify the full radius that it needed to be.
