Bearing Cup (old version)
Face Material (001)
Lightest possible grazing pass. Material is 12.7mm thick, I need 8mm of it, 3.175mm buried in the vise, leaving 1.525 mm to spare.
The end mill also will be clear of the vise in the Y axis, so going below the jaws in the Z axis is actually safe, but I'm shooting for a belt and suspenders.
;; ---------------------------------------------- ;; Face Material ;; ---------------------------------------------- ;; Zero X to right end ;; Zero Y to middle of material, 25.4mm from edge ;; Zero Z with 3" five-tooth indexable carbide facing mill ;; Set spindle speed to 500 RPM, 400 SFM, 6061-T6 with carbide allows 800. ;; Feed Speed 60mm per minute = 0.025 mm chip, 6061-T6 with carbide allows 0.05 G21 (set units to millimeters) G90 (set measurements to absolute, relative to machine zero) F60 (set feed rate to 60mm per minute) G0 Z20 (traverse to 20mm above part) G0 X50 Y0 (traverse to outside part) G0 Z5 (traverse to 5mm above part) G1 Z1 (feed to 1mm above part) G1 X-347 (feed to left end, 6 minutes run time) G0 Z20 (traverse to 20mm above part)
