Min. cut depth on surface

[bogusmill]

I am cutting an airfoil shape and leaving .05 mat'l for finish. I dont want to cut a lot of air so I set the minimum cut depth to 0.0, but it is still cutting above the mat'l by .04 The finish part is .01 below the mat'l stock. What will make it stop trying to cut above 0.0?

 

I'm using V9 SP1 and Flowline cutterpath.

Never mind I figured it out. The 0.0 min cut depth is from the amount to leave on drive surfaces, not the Z0.0 position.
