Good work John.

Is that the bench wobbling or the camera?

Yikes, that would be the bench shaking!

It's the stand, These were shot whilst it was on it's show transport stand C/W castors.
Rapids on this are about 120 in / min so it does throw itself round a bit.

Hi John,

What type of cutter were you using for the herringbone and helical gears.

Thanks
Phil

Phil,
Actually it was a bit of a bodge as it's a straight sided rack cutter off another job. It was done more to test the software program than to generate a correct gear.
I have since ground up some D bits with the correct involute but as yet haven't cut any more gears, maybe next week as I have a machine to test.

Hi John

Thanks for the feedback.

Have you considered to use the mill to produce the involute, with the blank in the spindle and a single point lathe tool in a vise on the table.

Also it seems to me there are a whole range of possibilities to produce gear cutters using a CNC mill, especially with a 4th axis.
