Follow a four-pass raster across a clamped billet. A rotating end mill sweeps a circular footprint through the height field; the model measures the union of removed grid cells instead of double-counting overlapping passes.
• A 3D process cutaway of a four-pass raster toolpath, end-mill sweep, cut depth and removed volume, with labeled components you can select. • Controls: Programmed feed (60-600 mm/min), Spindle speed (2000-12000 rpm), Cut depth (0.5-4 mm), End-mill diameter (2-6 mm), Spindle enabled. • Live readouts: Commanded XY distance; Path completion; Removed volume estimate; Feed per tooth · 4 flutes; Physical process time; Cutting enabled. • Three guided experiments (Fast versus slow feed, Overlapping cutter passes, Spindle interlock), a built-in model verification check, a timestamped event log, a trial report and a short knowledge check.
Feed velocity = feed / 60 mm/s Feed per tooth = feed/(rpm × 4) Removed volume ≈ removed cell count × 0.25 mm² × cut depth One animation second = 2 physical seconds.
Swept-disc 2.5D height-field removal with 0.5 mm cells. The tool starts at cutting depth; entry/plunge, tool deflection, chip evacuation, cutting force and chatter are not solved. Disabled spindle stops motion through an interlock. Dimensions, motion and process time are enlarged where stated for explanation. These are educational models, not machine programs or qualified production procedures.
Yes. Feed per tooth divides feed by speed and flute count.
No. Already removed cells are counted only once.
