Well I guess that settles that!

Nothing in my life, aviation included, requires more math than machining, manual or CNC. I don't need Trig for aviation but you sure do for machining, lol.

Flying the "big iron" you probably never have to figure a crosswind component, I only fly the "little aluminum" and sometimes the "little tube and rag", so it's more of a factor.

I smiled when I saw the comic posted on Facebook. I started out with CNC machines and now I own several manual machines as well. When you gist need ta waller a hole in something that ain't no point in taking all the time to sit that on that there computering thing and sit there and wright a big old fancy detailed program.

You must have gotten your CNC experience back in the dark ages. Simply drilling a hole would probably be better done on a modern CNC than on a manual machine. No need to sit down at a computer or write a big old fancy detailed program. All data entry would be done standing at the machine. You would enter the coordinates of the hole with respect to some position on the part. Then use the drill cycle, in the drill cycle you could choose straight through drilling, chip breaking or step drilling with full drill retract to clear chips between pecks, plus the option of a dwell at depth.

Everything would be the same effort manual or CNC until you got to the actual drilling. The CNC would excel because of the choice of drilling options. If the hole is deep you'll have time to clean off your work bench while the drilling is happening.

So you never used a sine bar before or a tooling ball?

Never,I enjoy designing different things related to my farming operation,mountain snowmobiles and shop related machines.I just machine whatever the particular job requires,probably not the correct way but usually get it done🤓

There are "Machinists", and there are CNC "Operators", some of whom may know how to actually do the work themselves.

I do trig all the time. And I do all my 'manual' milling on a cnc. (we don't have any manual mills anymore)

(this was me figuring out the non-circular boring/turning) (my daughter got my handwriting - poor girl..)

Bawahaha... you must have been educated at Assumption U.

I don't know all the details of every single g code but I have been known to stand at the machine cutting stuff entering code at the MDI interface one line at a time while the machine is running the last instruction I entered.

There are times when even the humble drill press is faster to get a job done.
