Sorry, but no...
a machinist that isn't able to read and measure a dxf file shouldn't be called that any longer IMHO.
A mindless tooling chimp is not going to cut it (excuse the pun
)
yes, it takes a minute or two, true,
but most effort is actually dependend on what material is being used as a blank and what machine is being used
(heat during machining and related shrinkage after cooling, machining tolerances etc...)
things I have zero influence of.
All critical measurements are given (you can even read them in the other images above)
regarding the tooth form, no tolerances have been added (and I will not even try
)
min/max values are given in terms of math equations you can drop in pitch roller diameter and toothcount
(a sensible way to dial in proper tolerances for the machinist)
And forgive me, but I do not care too much about if you need a slightly bigger shaft collar to install a grub screw,
or if your motor shaft is ever so slightly oversized so that you might need a bigger tolerance bore,
it's not important if the sprocket is 4mm or just 3.8.. etc etc..
So apart from the actual teeth everything's just winged.
(I think I took the hub 1:1 from your initial drawing so you'll find the numbers there)
if I now provide you with a fully measured technical drawing instead,
it WILL be lacking tolerances at the very least,
and the machinist will likely hand you a non functional part because of that.
And he'll truthfully tell you it's the fault of my drawing
Nope, I'm not going to waste your money that way I'm afraid.
If you want a truely impossible to falsely interpret /misread technical drawing,
with all proper tolerances and such,
you will need to find an engineer that'll draw it for you.
(will likely be more expensive than the machining itself [for good reason
])
Again, I'm sorry.. but I won't
