Most actual CNC code is generated by CAM software on a computer. Has been for 20 years or more. Those that can actually write G code by hand are few and far between.
Rotary table question, need help....

G code for a lathe and a mill was part of the curriculum at the local community college engineering course. Ironic, students that couldn't machine two parts that would fit together would ace the code courses.

In todays' "just in time" manufacturing environment, a CAD program can generate a complete job in no time,,, minutes if that long. Consider a complicated part can require 100,000 lines of code, how long would it take a proficient man to write that line by line? Margins are short! Not just in cutting time, but writing the program, also. Now, in comes "conversational programming". but you still have to know how to have the 'conversation'.

“CAD/CNC” machining is an effective solution for some components. However, those that only possess that knowledge base are often lost when the canned solutions don’t work. A classic example is “in place” machine repair where portable machining equipment needs to be designed and used. I looked for the “old timers” because of their knowledge base in setup and machining skills. Sadly, many have retired or shortly will

Even with a computer generated program it pays to go thru and check it. Even if all is well there may be places where you can save some time or simplify.

Only 25 years ago I started writing g and m code programs for lathes and mills with a drafting program
I would draw up the part and get my numbers from there and write the program.
And that evolved while I was running manual machines also the last ten years I I have programed and operated cnc mills
I love my manual lathe.

No mater how good I think I did on the program the moment I go to run it I find ways to Improve or speed up
All 234 of my programs that I use daily on my CNC mill were written by hand by me. Just another aspect of machining that I enjoy. If you don't start out on manual equipment before going to CNC you are kind of missing the boat. Speeds and feeds need to be learned manually in my opinion. There is no "feel" per say with CNC equipment.

Whaaa? You mean the tool bit manufacturers don't know ALL the proper speeds and feeds? Then again, they're in the business of selling replacements.

I thought this was about adjusting a feller's rotary table?

I dint mean to derail
It is pretty old thread and I've been derailed from this site for a while by endless derailing project's
