Planning feeds for aluminum. Raster entry includes full-width cuts; verify the tool maker’s slotting and ramp limits.

How motion is timed

Each line uses its length; arcs and helices use their true curved length. Time includes acceleration and deceleration to a stop at each logical move. Circular feed is capped by the entered acceleration and radius.

This assumes exact stops, a scalar acceleration limit and no controller look-ahead. The constant-feed figure excludes those effects. Neither figure is a measured machine cycle.

Price = cost ÷ (1 − margin). Same process at every quantity; no pallet, multiple-part fixture or automation savings assumed.

Scope of this first example. The blank is already square and faced. This plans a pocket with 6 mm corner radii and removes 10.61 cm³. No outside profiling, holes or threads. There is no stock-removal simulation, fixture / holder collision check, tolerance allowance, tool-life validation or executable machine code. Prices exclude scrap, coatings, freight and tax. Shop review and a CAM or machine-time comparison are the next validation step.
