Mr. Machinist: CNC & Shop Math

The ultimate machine shop & aerospace companion. Master shop math, blueprint layouts, and AS9102 inspection directly from your workbench!

Welcome to Mr. Machinist – The simple, down-to-earth shop calculator app built for CNC programming, machine setups, part inspection, and manual machining. Whether you’ve been running parts on the shop floor for six months or thirty years, this app helps you double-check your blueprints, nail your angles, optimize CNC speeds and feeds, and keep from scrapping expensive material.

The math formulas and shop math shortcuts built into this app aren't new—shop hands have relied on these core engineering setups for decades. But instead of flipping through grease-stained reference books or scratching numbers on a piece of cardboard, Mr. Machinist revamps those time-tested shop methods into a clean, modern app that fits right in your pocket.

The author behind the app has spent 46 years in manufacturing, precision machining, and aerospace quality inspection, running into the exact same blueprint headaches you face every day. This app is a practical way to pass those everyday shop-floor solutions down to the next generation of operators looking to sharpen their skills, master CNC setups, pass part inspections, and learn how to get hired at top shops. No confusing engineering jargon required—just punch in your numbers and get accurate blueprint answers instantly.
