This is spur gear involute calculator.

Most of the spur gears are made up from gear hobbing technique.

With the development of technology nowadays gears are made from CNC (Computerised Numerical Controlled) machining. The basic inputs for the CNC machines are the co-ordinates of the gear and other machining inputs required for machining a gear from a metal block.
This program helps in calculating the co-ordinates of a spur involute gear from the given inputs like:
1) Centre distance between the two shafts.
2) Teeths required on the gears.
3) Pressure angle of the involute.

The points taken from the program are ready to be given input to any CNC making a gear profile.

The involute profile was derived from "Earle Buckingham's" formula.
