MachineMate Engineering

Stop flipping through greasy handbooks and second-guessing your math. MachineMate puts four essential machining calculators in your pocket—beautifully designed, lightning-fast, and built for the high-stakes environment of the modern machine shop. Whether you are running a CNC center or a manual mill, MachineMate delivers the industry-standard data you need to work with total confidence. Four Essential Shop Tools ISO Fits & Tolerances: Designing mating parts? Get instant upper and lower deviation limits (in micrometers) for any combination of hole and shaft tolerance grades (H7/g6, H8/f7, p6, and more). Eliminate costly assembly failures before the first chip is even cut. Feeds & Speeds Calculator: The heart of efficient machining. Input tool diameter, cutting speed, flute count, and chip load to receive optimal spindle RPM and feed rate (mm/min). Protect your tooling and hit your target surface finish every time. Tap Drill Size Finder: Fast lookups for metric threads from M3 to M20. Instantly find the correct drill diameter and thread pitch for standard metric fasteners. Bolt Hole Circle Coordinates: Laying out a pattern? Enter the number of holes, circle diameter, and starting angle. MachineMate calculates precise X/Y coordinates to three decimal places—ready for direct CNC programming or manual layout. Built for the Shop Floor MachineMate features a specialized Neumorphic UI designed to reduce eye strain during long shifts. It isn't just a utility; it’s an ergonomic tool designed to be used with one hand while you're standing at the machine. Why MachineMate? 100% Offline: All calculations happen locally on your device. No signal? No problem. Engineering Rigor: Every formula follows standard mechanical engineering relationships and ISO standards. Zero Friction: No logins, no ads, and no bloat. Results appear the moment you tap "Calculate." Lightweight & Fast: Optimized for both iOS and Android to ensure it never slows you down when time is money.
