Engineer's Mate: Professional CNC & Machinist Calculator
Stop flipping through handbooks and searching for "the black book." Engineer's Mate provides instant, shop-floor-ready data for CNC programmers, toolmakers, and mechanical engineers. Get precise calculations for every setup, from Speeds & Feeds to ISO Tolerances, directly on your device.
WHY CHOOSE ENGINEER'S MATE?
Manual handbooks are bulky and slow. Engineer's Mate puts a comprehensive engineering reference in your pocket. Whether you need to look up metric tap drill charts, solve complex shop trigonometry, or verify H7/g6 fits in seconds, this is the essential tool for precision manufacturing.
CORE MACHINING & ENGINEERING TOOLS:
● Speeds & Feeds Calculator: Optimize cutting parameters for milling and turning. Get reliable guidelines for various materials, from Aluminium to Stainless Steel.
● Thread & Tap Reference: Access complete tap drill size charts for metric and imperial threads. Find the correct drill bit for any tapping job instantly.
● ISO Fits & Tolerances: Eliminate guesswork. Quickly determine clearance, transition, or interference fits using a professional tolerances calculator based on ISO standards.
● Precision Shop Geometry: Powerful helpers for jig boring and layout, including bolt circle patterns, arc radius (chord/sagitta), and sine bar calculations.
● Trigonometry Solver: Specialised right-triangle trig tools to calculate angles, offsets, and geometry for complex CNC setups.
● Unit Converter & Material Data: Seamlessly convert between Metric and Imperial. Reference thermal expansion rates and torque basics for secure assemblies.
