Re: [CAD_CAM_EDM_DRO] Re: CNC coil winder traverse

Actually, the wire 'jumps' over the groove about once a revolution. Don't
forget that the wire is being wound in a right-hand helix, going one way,
and as a left-hand helix on the reverse cycle. The tendency is to 'lay in
the groove' for only about 1/4 of a revolution, then, it's 'climb to one
side. or another, until it's time to 'jump over' again. What in the world
are you winding that's so critical that it needs 'perfect lay'? I used ta
work for a company that mfd transformers with wire as small as #40. That's
about 0.0037" dia, for heavy enamel insulation! (you figger it out, how
many mm's.) Anyways, these were layer wound on bobbins, and there were a
few minor adjustments that the operator made to prevent bunching up, on
either end of the flanges, but once set-up, they could run a whole 10 lb
spool without problems.

p.s. the largest wire we used was three-of 0.589 sq copper (with 3/8" dia
hole thru center for water-cooling). After rectification, that
(three-phase/inter-phased/zig-zag wye) power supply was capable of 30,000
Amps DC at 30 Volts! No, wait, I remember a single phase unit that had a
half-turn of 1/2" x 8" busbar for it's secondary.
