Help with tapered holes

[phill05]

Here one to try,
Example to draw a ER32 collet holder: Draw out your largest circle say 32mm dia within draw smaller circle say 25mm dia, draw another circle say 17mm Dia, draw a vertical line 9mm long starting top of largest circle down towards centre select and circular copy this say 400 times ( the more lines you copy the smoother the finish) x 360 degrees.
Select smallest circle "pocket toolpath" to full depth say 36mm,, select all circular copied lines "Fluting tool path" run preview job done.
Hope it helps.

Have tried your idea out in VCarve, its a nice one but takes too long to generate the hole. And my machine will not take a massive ramp up in speed and feed rates to reduce the cycle time to a respectable level. Pity because I like this approach. Thanks for the input.

You can put less lines in I copied 400 times for a 12mm end mill to give you a superfine finish less would be quicker, play around until you find best to suit your setup.
Plug in "chamfer" only works in V9 I think.
