Hu;
Late reply, have been practicing in the pool hall

I'm not going to make a big argument about this but:

My video is from elsewhere, I said the same process.
Well, the way you wrote it pretty mutch indicated that the video previously linked (Bob) was performing additional "handwork" on the bottom of the V groves.
In addition it was read as that the work performed would not be as good as for other mechanical tools.
I can tell you that this is not the case. Bob has
never done any additional "hand work" on his V groves. I know, I discussed this with Bob today !!

The inside corner of the "V" is unsharp enough that it results in less than a perfect fit with a sharply cornered, true, freshly final cut point. Another issue is that a 90 degree tool often doesn't cut an exact 90 degree vee in wood leaving hand fitting to be done between the woods. The other options are to use extreme pressure to fit the parts together leaving residual stress in the finished cue or to fill the gaps with glue, leaving glue lines. What you may find acceptable in production is not acceptable in a decent custom shop.
Again, you are generalizing here and are you correlate this to all CNC machines? In case I think you should be humble enough to mention which equipment you are using and link the problems to the machine you have this experience with.
There are many different types of CNC equipment and generalizing like this might not be the correct way.

Your own video proves your words I emphasized in red false and also answers any question of which of us has a better understanding of shop practices.
I have no video on my web pages concerning CNC, nor have I linked to any web pages showing any CNC work. I think you need to go back and have a look.

He makes four passes before rotating the wood. He grabs the wood every pass without fail. Either he doesn't understand shop safety which I would be amazed to learn or he is doing it for a reason. When he is through cutting he grabs the indexer not the wood to rotate everything. He never touches the wood when he is rotating it and indeed can not rotate anything without unlocking the indexer. One handle unlocks my indexer and is used to turn it also. Pretty standard and I suspect his is set up just the same.
The reason for Bob was holding his hands on the forarm was that he had at the time the video was done, some problems with vibration, due to a to light headstock on his setup. This has for sure been changed and has nothing to do with the CNC machine !
I think also you missed the point I was trying to make; He was waiting there to change the indexer. Of course he's not changing the axis while the machine is cutting... He could of course sit down and look, but the point was that he manually changes the 4th axis index.
There's no need to "watch dog" the machine as you indicated if you don't feel like it.
Health and safety is far from this discussion and has noting to do with the discussed subject.
That is something each and every one of us must consider in it's own way.
Anyway, I thing we are migrating far from the initial subject, so I just finnish my post on this by saying that Bob has not the problems you have been emphasizing just to let the other readers know this.
