About CNC Material & Calculator

The CNC Machinist Handbook is the ultimate digital assistant for machinists, CNC programmers, and manufacturing technologists. It is designed to make daily workshop calculations and data lookups simple, fast, and highly accurate.

Key Features:

🔹 Speeds & Feeds Calculators

Cutting Speed (Vc) & RPM (n): Optimize milling, turning, and drilling operations with a single tap.

Feed Rate Calculation: Precise calculations based on feed per tooth (fz) or feed per revolution (f).

🔹 Geometry Module

Triangle Calculator: Quickly determine the sides and angles of any triangle (Sine/Cosine theorems).

Polygon Calculator: Calculate inscribed/circumscribed radii and side lengths for regular polygons.

Bolt Circle Calculator: Efficient bolt hole pattern generation with G-code output for precise positioning.

🔹 Material Database & Machinability

Comprehensive Library: Organized lists of Steels, Stainless Steels, Cast Iron, Aluminum, Copper, Plastics, and Superalloys (Titanium/Nickel).

Machinability Index: Instant visual guide for every material:
1 (Green): Excellent machinability.
3 (Yellow): Medium machinability.
5 (Red): Critical/hard to machine.

🔹 Surface Finish & Hardness

Roughness Converter: Theoretical surface roughness calculated from insert radius (Re) and feed rate.

Hardness Converter: Quick conversions between Brinell (HB), Rockwell (HRC), Vickers (HV), and Tensile Strength (Rm).

🔹 G- & M-Code Reference

Standard Codes: Detailed explanations of the most common G and M codes.

Custom Code Management: Add and save your own custom G or M codes. Keep your machine-specific instructions (e.g., Fanuc, Heidenhain, Siemens) right in your pocket.

Why Choose This App?

Multilingual: Available in an impressive 20 languages (including English, German, French, Italian, Spanish, and more).

Full Offline Support: No internet connection needed on the shop floor; all calculations and data are instantly accessible.

User-Friendly: Modern, dark-mode optimized interface that prevents eye strain during workshop use.

Optimize your manufacturing processes, reduce programming time, and increase precision with the CNC Machinist Handbook!
