Art Fenerty, the writer of Mach3 has been writing a new program for cutting gears.

I have been working with him sorting out the spur and helical gears side to it,

Where this program scores is that it can cut a gear with a normal off the shelf end mill, no special cutters needed.

These were cut using just a 3mm end mill.



Today, first paying job was to make this bent and broken pinion gear.




Into this.



Done with a 1.5mm cutter.
