Coil winding machine ( Wizard needed)
ynneb:
There is some talk in another forum about making a coil winding machine, for winding transformers, guitar pickups etc.
I was wondering if the was any wizards in Mach that does this?
How hard would it be to make a wizard that takes ito account.....
Wire thickness
Spool width
Spool thickness
Adjustments for each layer of wire ( as the spool gets thicker)
Etc
Has any one done this?
I think this could be a really handy feature in addition to Mill, Turn, you could also have Wind.
Dumb Idea?
Please forgive me if this has already been discussed.

Benny that pic looks great.
I was thinking about winding coils also, I need to wind some solenoids. It seems to me that a wizzard for lathe would make more sence. If you think about it laying down coils is a lot like cutting threads.
If you added a spool diameter and had a lookup table you could also calculate coil resistance based on the wire diameter and calculate how many feet were going to be used. You would also need to know the bare copper wire OD and the wire with the insulator OD. for example I looked up a 24 gauge wire..
BARE WIRE SPECIFICATIONS:
DCR based on resistivity of 10.371 ohms per circular mil foot @ 20°C ( 100%IACS Conductivity)
AWG Bare Min. Bare Nom. Bare Max. DCR Min. DCR Nom. DCR Max. cmils feet per lb
24 0.0199 0.0201 0.0203 25.17 25.67 26.19 404 818
INSULATED WIRE SPECIFICATION:
Values listed below are derived from the NEMA MW1000-1997 Standard or MWS Wire Industries internal inspection criteria
Insulation Build Insulated Min. Insulated Nom. Insulated Max. Film Increase Min. Feet per LB.
Single 0.0209 0.0213 0.0217 0.0010 804.5
Heavy 0.0218 0.0223 0.0227 0.0019 790.5
Triple 0.0228 0.0233 0.0238 0.0029 776.5
Quad 0.0234 0.0242 0.0250 .0035 762.5
As you can see the diff between the single insulated and the quad is 42 feet per LB, or 435.582 ohms.
It would be great to calculate impedance, however this becomes difficult because of the difference of the bobbin and the frequency.
Any how just some food for thought..

http://www.circuitcellar.com/renesas/winners/3339.htm that is one place but no help. Few months ago was an issue of Nuts and Volts that had a project. I have that issue but finding it is a problem right now. Mike

howdy all just found this site but also on the zone one thought on this because i wind pickups also is on the movement if it works to where it starts at 0 then just steps the size of the wire to the end of the bobbin then back to bobbin theres a prob you will get more capacitance and thats where the probs come in for a pick up you need more of a variable movement i guess what i'm trying to get at is a random time for movement and random amount of movement on the winder i built it origanally had a cam for the movement and it gave about the same sound each time to get different sounding pups i had to start guiding the wire by hand which did give me different sound i guess if there was a way for the cnc to let you teach the movement would be nice too as you could lay different pup styles and save the gcode for it
Strat:
i don't have a cnc winder setup at this time but i do have the things {motors ,drivers ) that i could build another one with if your game on the code i would be more then happy for testing and setting up a cnc winder i guess the big things (for me ) would be bobbin size or fill area # of turns and the ability to "learn" the movement or the option of random movement
another thing that would be nice is if i could enter the wire varibles ohms per foot wire size and enter the amount of resistance i would like to wind and have it calculate the # of turns theres a guy on another site i hang on that wrote a calc/counter program but to be able to do it in cnc would be really really nice
