Hi,
I am trying to cut a parabolic curve in a piece of sheet metal using a numerically-controlled cutting machine (basically a very hard rotating router blade). The router blade is 10mm diameter. I want to achieve a parabolic cut in the sheet metal that adheres to the formula y=x^2
The trouble is, if I cause the axis of the 10mm router blade to travel along a parabolic path with formula y=x^2 I do not get the resulting top and bottom cuts to be parabolas that conform exactly to the formula y=x^2 This is due to the thickness of the router blade and the fact that it always cuts at a point that is normal to the parabolic path that the axis of the rotating blade is traveling along. I guess that if my router blade was of infinitesimally small diameter, I would then get a faithful cut in the metal that conforms to y=x^2
Can anyone please tell me the parabolic formula that the axis of a router blade of certain thickness would need to travel along to produce a parabolic cut that conforms to the formula y=x^2
Thanks,
Joe.
