As a former Doosan/DN employee I can tell you that the sales crew gets very aggressive with discounts at the show. Bring your check book.
The last IMTS was the first one I've missed since 1982. They're like Disney for machinists. Allot yourself plenty of time, and comfortable shoes.
I always recommended having a "Master Program" on the CNC side control everything else.
So, the Master Program would call the pallet, then sub down to the data server, then return to the Master to index, then back, etc.
Many years ago, when I opened my first shop, I bought an inexpensive spin/index fixture from one of the catalogs.
I had never seen one used, and dad had never owned one, but I thought it could come in handy, and for the price, it was worth it to experiment.
One I saw what could be done with it...
Titan is good for video work, and he has some interesting stuff.
NYCNC is pretty good.
The MTB's all have channels that are well put together.
Joe Pie has some good stuff.

I've met a lot of machinists who were better than me.
Funny thing is, they all thought I was better than them.
One thing about this business, you can never learn or know it all - and that's a good thing - there's always something new to learn.
If you go through thinking you've got to be the...
Many leaks are in areas hidden behind covers.
Look for fluid piling up under turret covers, on the bed casting behind the Z axis, and on the motor compartment floor.
M31 - Spindle interlock bypass - allows the machine to operate with one cycling of the chuck. However READ YOUR MACHINE MANUAL. It may be different for you.

If you're Doc says you're good, you're good.
It didn't break the skin so zero chance of rabies infection, if the thing even had it to begin with.
Now, off to the bat lathe!
Dad owned a gear house.
So, here's a few things to consider:
With a lathe you can turn the blanks. With a live tool, Y axis lathe you can turn and hob the gears.
With a mill you could mill the teeth.
However, there are different grades of gears and the markets you pursue will have a lot to do...
MSC and other houses have machinable wax which can be measured and Q/C'd as well as cut.
However, for me, I usually toss in a piece of aluminum scrap, and go the single block/rapid down/hand on the knob/look at the distance to go route.
Sounds like perhaps a fixturing issue.
If the screws and bearings are new, and the ways are in good shape I can't see why the machine would react that way under 100 rapid.
May sound obvious, but, is everything tightly fastened down?
There are a few things to look for, IMO.
On many taps, the last few "threads" are tapered up and therefore, won't cut. Trying to tap all the way to the shank is a near guarantee of snapping it off.
There are extended flute taps that can alleviate this situation.
@Fal Grunt Is your machine capable of using Full Contact tooling?
When I worked for Doosan/DNS we would run demos using that and saw quite an improvement in tool life.
The reason is usually the spindle drive(s).
I used to work for Doosan/DNS and this was normal for our sub spindle machines. Crank one up and let the other coast, once up to speed, then sync.
