Drop Hole O-Ring Groove Toolpath Help

Hello,

I need some help with a tool path.  I'm machining an o-ring groove with an offset drop hole using a Parker-Hanifin cutter from Harvey Tool.

Obviously, I want to start and stop at the center of the drop hole; I'm able to get the inside of the tool path to work however not the outer.  When I attempt the outer it ignores the predrill start/stop location and plunges in the center of the groove.

I've tried all I can imagine to get it to work; I've attached the file so you can have a go at it.  Thank you in advance!

Sincerely

Dale
