Forward is just like a drill press...CW as viewed from above.

Clockwise is always forward on a mill. Drills, end mills, reamers...ect are all normally made for clockwise use.

Which way does it go
Except for very special, and rare uses, all rotary cutters turn in a clockwise direction. However, the helical fluting on end mills, taps, etc. can have a have a left-hand helix. This has the benefit of pulling cuttings up and out of the way. For example: when tapping a blind hole with left-handed fluted tap will pull the chips out of the hole, rather than packing them into the bottom.

Rotary cutters cut in the CW direction as said.
However there is two ways to move the job against that cutter.
Climb milling and Conventional milling.
Climb milling is where the cutter teeth move against the metal in a kind of the same direction and sort of pull the steel through.
This can creat higher cutting forces and should not be used for small cutters and dovetail cutters.
Conventional milling is where the cutter teeth move against the metal in the oposite direction of travel kind of trying to push the job back away from the cut.
If you are new start with conventional milling . Just place the cutter near the edge of the job and imagine the rotation of the cutter and the two directions that the job can move and you will soon umderstand the difference.
Slot drills cutting in a slot are climb milling and conventional at the same time on opposite sides of the cut . The job direction does not make much difference.
