Its nice to see all the suggestio
ns.. LEt me touch on my general feeling at the moment.
1) Bevel Gears.
The last iteration of bevels puts out code for making them on 4th axis with a tapered cutter thats tapered to the pressue angle. ( a 40 degree taper woudl be used for a 20PA bevel for example. ).
That code is complete, but untested. Ill wait on bevels until someone, including myself, gets brave enough or has enough time to waste to try them out. Ive verified them graphical
ly, but not on a real 4th axis.
2) Tapered machine tool OR fly cutters. Fly cutters wont be difficult, I can probably add that after I do an escapemen
t. Taper requires a bit more work on my part to verify the math. ( Many idea's weve all had turn out ot be impossibl
e mathwise, though you wouldnt think it at first glance..
Racks I think will follow cutters. This is because Id prefer they be part of the generalis
ed toothing algorithm approach. IF a generalis
ed toothing algorithm is possible, ( again that math verificat
ion thing..), then applying such an algorithm to a straigh line makes a rack, to a circle makes a spur, and to an ellipse makes a elliptica
l with proper pressure angle variation
s, unlike the osculated circle elliptica
ls we currently have. This is also true of internal non-circulars. In fact a generalis
ed algorithm would make much of GM's current code obsolete, and could force a rewrite of various sections to take advantage of such a thing... IF its posssible
.. This would also allow one to make an interrupt
ed gear .. I would need a way for you to draw shapes though.
4) Roots Blowers..
I find these facinatin
g as well, and I suspect I make get tempted to make them soon. But I wont promise that till Im closer to them. They do look pretty interesti
5) 3d Printer stories.
We are still working , albeit slowly on our 3d printer. At this moment, we're using a water filter as a holding vessle for water, a compresso
r feeding it with up to 80psi, and a fuel injector from a buick ( we think..), to control the water flow via pwm in Mach3. (This uses Mach3's laser pwm control mode, rarely used by most.). The fuel injector works, varies its spray densisty according to motion speed of the head and we hope to run many more tests over the coming winter. Its out hope to "print" on a bed of concrete or qucik plug..som
ething that has fast reaction to water to make 3d items out of concrete.
. Ill post photos and experienc
es as we go.
SO basically, Im intereste
d in doing almost all the current suggestio
ns, but being the lazy bastard I am, I will attempt the ones that will hurt my head the least, or that stand a change of turning me obsessive which is how I usually get past challenge
s to my manhood like "general toothing theory".
e all the suggestio
ns though, all are considere
d, and sometimes a new suggestio
n will move to the head of the developme
nt list, just because it piques my interest to that level. We'll probably have many iteration
bs of "This is whats next" as things change, so keep suggestin
g as you think of anything that you figure you need. Sometimes they take awhile as I cant figure out a way to do them,
ct things allow other things to be done. ( A form cutter allows worm gears for example..)
Thanks as always,
