CNC Workpiece Calculator

CNC Workpiece Calculator gives machinists and engineers a quick way to check centering offsets, ISO hole and shaft fits, geometric tolerances, and material weight estimates without leaving the workstation. Enter workpiece dimensions, choose the desired tolerance class, and review the resulting limits and guidance in a clean layout optimized for both iPhone and iPad. • Centering helper with live geometry hints • ISO hole/shaft fit lookup covering common tolerance classes • Material weight calculator for rods, tubes, plates, and custom stock • Probe animation reference plus quick notes for shop-floor checks • Works entirely offline and keeps inputs available during multitasking
