Precision Gear Design,
Accessible to Everyone

GearForge provides free, professional-grade gear generator tools for engineers, designers, students, and makers worldwide.

Our Mission

We believe that precision engineering tools should be accessible to everyone — from professional mechanical engineers designing industrial gear trains to hobbyist makers building their first CNC project. GearForge was built to democratize gear design by providing mathematically accurate, easy-to-use tools that run entirely in your browser.

What We Offer

GearForge provides a suite of interactive gear generator tools that calculate proper involute tooth profiles, display real-time previews, and export production-ready files. Our tools cover the most common gear types used in mechanical engineering:

  • Spur Gears — The most common gear type for parallel shaft power transmission
  • Flat Gears (Racks) — Linear gears for converting rotational to linear motion
  • Internal Gears — Ring gears for planetary gear systems
  • Helical Gears — Angled teeth for smoother, quieter operation
  • Bevel Gears — For intersecting shaft applications
  • Rack & Pinion — Matched gear sets for linear actuation

Technical Accuracy

Our generators use standard gear mathematics including involute curve calculations, proper addendum and dedendum ratios, and standard module/pressure angle systems. The output is suitable for CNC machining, laser cutting, 3D printing, and educational purposes.

No Registration Required

All tools are completely free to use with no account creation, no usage limits, and no watermarks on exported files. We believe in keeping engineering tools open and accessible.

Mathematical Precision

Every gear profile is calculated using proper involute mathematics. We use industry-standard formulas for pitch diameter, addendum, dedendum, and tooth profiles.

Instant Results

All calculations happen in your browser — no server processing, no waiting. Adjust any parameter and see the result immediately on the interactive canvas.

Production Ready

Export as SVG for direct import into CAD software and CNC controllers, or PNG for documentation. DXF export is also available for select tools.

Always Free

No subscriptions, no freemium tiers, no hidden costs. Professional gear design tools should be accessible to every engineer and maker.
