Trouble with CAM Curved Pocket for guitar

[dmac252a]

I'm Working on an Archtop electric Guitar. All the toolpaths and milling were fine and I decided to add an access opening in the back plate.  None of the Toolpath Options I have tried has enabled me to get a smooth shelf for the cover to sit on. Would greatly appreciate some assistance/guidance File attached

Thanks

Dennis

Accessibility analysis shows that this red area cannot be processed from the current processing direction.

If we take that into account and process as much as possible, Scallop may be the easy way to go. 

A small-diameter ball end mill was selected to machine the corners as much as possible. If you want to machine more corners, you can use a narrower end mill.

 

 

I have attached the file for your reference.

I just ran the toolpath with a couple of changes  1 parameter tool inside boundary and 2 halved the stepover and It good worked great

Thanks for jumping in.  sometime we cant see the forest for the tree
