We have a new to us CNC machine (Fryer MB-14 Bed Mill 5hp spindle 4200 RPM max). We are using HSMExpress CAM software in SolidWorks.

Hoping for a little help selecting the best technique(s) for pocketing and contouring. Consider a 1/4" AL gear plate that requires several pockets and the outside contour. We have 1/4", 1/2", and 3/4" carbide and HSS 2-flute end mills available.

For the pockets should we use:
a) the 2D Pocket operation which plunges/ramps to a depth, clears the entire pocket and then repeats at the next depth.
b) the 2D Adaptive Clearing operation which seems to spiral down through the entire depth and then works its way out until the pocket is cleared.
c) other?

For outside contour should we:
a) ramp/contour a groove down until the depth is reached?
b) work for the outside and come in similar to the adaptive clearing?
c) other?
