Creating precise involute Spur Gears using Excel and Autocad

The tutorial should explain how to generate gear profiles using excel.

First Download and open the Excel spreadsheet "Gear Calculator" attached.

You can find all tutorial graphics in the RAR file.

You can see an example here:
15 Tooth & 18 Tooth gears meshing

You could also use the dxf builder at www.me-bac.com for normal spur gear and also for corrected gear.

Thank you
