About Engineer's Mate
Engineers Mate: The Ultimate Machinist Calculator & Engineering Reference
Engineers Mate is a professional-grade machinist calculator and on-the-job reference designed for mechanical engineers, toolmakers, and CNC programmers. Whether you are at the machine, the bench, or your desk, this app provides the critical machining data and engineering formulas you need to move from setup to first part with precision and confidence.
WHY CHOOSE ENGINEERS MATE?
Manual handbooks are bulky and slow. Engineers Mate puts a comprehensive engineering reference in your pocket, allowing you to quickly look up drilling and tapping data, solve complex trigonometry, and verify ISO fits and tolerances in seconds. It is the essential shop tool for anyone working in precision manufacturing.
KEY FEATURES & MACHINING TOOLS:
● Drilling & Tapping Reference: Access a complete drill size chart for common tap sizes and thread recommendations. Find the right drill bit for any job instantly.
● Speeds and Feeds Calculator: Optimize your cutting parameters with reliable speeds and feeds guidelines for various materials and tooling.
● ISO Fits and Tolerances: Quickly determine clearance, transition, or interference fits using our integrated tolerances calculator based on ISO standards.
● Precision Trigonometry Solver: Use our right-triangle trigonometry tools to calculate angles, lengths, and offsets for complex setups and geometry.
● Jig Boring & Shop Geometry: Simple, powerful geometry helpers for precision work, including arc radius calculations (chord and sagitta) and jig boring values.
● Engineering Unit Converter: Seamlessly convert between metric and imperial units for shop and design work, covering length, temperature, and torque.
● Fastener & Torque Data: Reference fastener preload and torque basics to ensure every assembly is secure and meets specifications.
● Material Properties: Estimate thermal expansion and bending allowances for flat patterns and bend deductions.
DESIGNED FOR YOUR WORKFLOW:
Engineers Mate is built for the "hands-on" professional. It reduces the need for manual calculations and double-checking, helping you reduce scrap and make better decisions on the fly.
• Machinists & CNC Programmers: Get the G-code-ready data you need for milling, turning, and drilling.
• Mechanical Engineers & Technicians: A reliable companion for verifying design tolerances and material growth.
• Fabricators & Toolmakers: Speed up your layout and setup process with precision math tools.
• Students & Hobbyists: Master the essentials of precision machining with a clear, easy-to-use interface.
