Chuffed as chips ! Wire EDM

Today I'm walking around with a silly grin on my face and chuckling! I have finally ironed out most of the wrinkles from a 1984 Fanuc Tape Cut Model M
wire EDM machine which has involved sourcing obscure key board modules, odd Japanese panel switches, and finally getting and installing a memory upgrade, no not sims, but bubble memory! To say nothing of learning the intricacies of both Fanuc's version of G code, but it's application to a four axis wire cutter as described in an operators manual that due to being handled in a wet environment for neigh on 30 years is in a similar state to the Dead Sea Scrolls, and is written in an 'interesting' version of English where sentence order is apparently immaterial so long as the words are there somewhere !
The final test was to draw a 32 dp 32 tooth gear in a cad package, transfer it to FeatureCAMs wire eroder CAM package, produce G code, download to the Wire Cutter and slice up a bit of steel into a gear wheel. I didn't need the gear, but by heck it was satisfying making it <G> It opens up all sorts of possibilities as so long as the material conducts electricity it will cut it. Even carbide tool inserts! Custom threading inserts cut from plain turning ones come to mind.

Now I know who can make me some custom internal stub tooth involute slotting tool inserts.
So how long did it take to cut the gear ?

Actual cutting time about 70 mins but I'm being conservative with the cutting conditions as it's a pain in the rear end re-threading the wire after a wire break! Be far far quicker to hob it, but that's not the point. Anyway you couldn't hob it if it was a pre-hardened & stress relieved steel.
As for your internal stub tooth involute slotting tool inserts, if you can draw it and export as a dxf I can probably cut it!
