CNC Machinist Calculator app analytics for December 21

Meet Milling • Drilling • Turning — the pocket‑sized industrial calculator trusted by CNC programmers, tool‑room veterans, and manufacturing engineers worldwide. In under a second, it turns scribbles on a setup sheet into exact spindle RPM, feed per tooth, horsepower draw, coolant flow, tolerances, and even G‑code patterns — no spreadsheets, no rules of thumb, no signal required. 16 production‑ready tools (offline) • Milling Speed & Feed • Milling Horsepower • Milling Step‑over Distance • Drilling Speed & Feed • Drilling Horsepower • Drill Size / Tap Drill Look‑up • Tap Size (pitch & class) • Turning Speed & Feed • Turning Horsepower • Turning Surface Roughness • Thread Milling (helical path, arc length, chip thinning) • Tool‑Life Predictor • Coolant Flow & Nozzle Velocity • NEW: Tolerance & Fit Calculator (ISO 286 / ANSI B4.1) • NEW: G‑Code Reference Library & Quick Generators • NEW: Chip Load & Tool Deflection Calculator What’s new and why it matters • Tolerance & Fit Calculator (ISO 286 / ANSI B4.1) • Pick standard fits (e.g. H7/g6) and get upper/lower limits, deviations, and fit type (clearance/transition/interference) instantly. • Visual tolerance zones help with assembly planning and inspection. • Inch/metric aware, with save/share for traveler notes. • G‑Code Reference & Quick Generators • Clean, searchable G‑ and M‑code library with categories, formats, and examples you can copy to clipboard. • Quick Generators: Bolt circle, rectangular and linear patterns, plus arc‑center from 3 points — perfect for one‑off ops and quick CAM notes. • Chip Load & Tool Deflection Calculator • Computes chip load per tooth, cutting forces, bending stress, overhang ratio, and tool deflection (µm & thou). • Chatter risk score with visual indicators and actionable recommendations. • Material‑aware defaults for tool and workpiece; supports carbide/HSS and common alloys. Why machinists keep it on their home screen • Built for the shop floor — big type, dark mode, glove‑friendly UI; works 100% offline. • Verified formulas & data — derived from ISO, ASM Handbook, and Machinery’s Handbook; peer‑reviewed by veteran machinists. • Inch/metric in one tap — instant unit swap, plus surface speed, chip‑load, and MRR summaries. • Smart defaults — choose tool material and workpiece alloy to pre‑fill recommended SFM and fz. • Save & share — bookmark setups, copy results to CAM notes, or AirDrop to the operator. • Light on battery, heavy on accuracy — single‑screen calculators to keep you cutting, not tapping. Built to boost OEE and quality • Hit first‑article faster with fewer test cuts. • Reduce scrap and rework through predictable feeds, speeds, and fits. • Improve tool life with correct chip load and deflection control. • Communicate clearly — standardized results you can paste into setup sheets. Always improving We ship practical, production‑ready tools that machinists actually use. If it doesn’t help you ship parts, it doesn’t ship in the app. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
