Thanks! The radius is .160 and I was hoping to use a 3/16 Ball End Mill, not sure if that complicates anything: Here's the file: Radius with Ball End Mill.emcam

I want to machine the radius of my part with a ball end mill but cannot for the life of me figure it out. I know there should be an easy way to do this using a 2D Contour however whenever I try the toolpath either starts milling straight into the wall or gives me an error message. I've attached a picture of the radius below, any help with where I'm going wrong (Chaining? Wrong toolpath?) would be appreciated.
