    Seriously, ya'll make me worry sometimes.

    Learn the control that's in front of you. We could argue the merits of which is the best, but that wasn't the question. In practice they are all reasonably similar.

    I've trained a LOT of people over the years on Fanuc, Siemens, Mazak, and (recently) Okuma. The majority of smart, young machinists can pickup enough knowledge to touch off tools, load programs, and edit code in two days or less. That is enough for 99% of what needs doing in a modern shop. There is a small group that take months to learn a controller, but if you're in that group, then you are really going to struggle with the CAD/CAM side.

    So.... whatís the difference between these controls? I started on Yasnac, and by started I mean I stared as the screen rolled on and made parts while I burred. Eventually graduated to hand-jamming and pencil cam. When I moved to another company, it was with Haas mills and a few Okumas. At my own shop, I have a Fanuc.

    From what Iíve seen... I just donít see enough of a difference. Itís not like French versus English, itís more like a fake Boston accent versus a real one. Sure, they have variations on certain things, but worst case scenario, it takes you a second to translate. Iím sure thatís not the case for every control, but still.

    I was asking a technician buddy about live tooling, Swiss machines, and dual spindle lathes the other day, just curious about how the programs look and are read. His comment was he doesnít really write programs as much as he edits his post processor, which echoes many of the folks on here. My question, for you guys who have used multiple CAM programs; how different are the post processors? Are there enough similarities that learning one is more than a head start for another or are they all totally different beasts?

    Are the following Fanuc controls considered full-blown CNC systems?

    Fanuc Professional Jn (20FA)
    Fanuc 21i Professional
    Fanuc ProEn

    These are all offered on the Makino KE-55 3 axis mill.

    Are these Fanuc controls just as capable as a Haas control on a 3-axis Haas ? Or much more capable?

    Moraine Valley? If so the instructor I know up there is a good guy.

    Concentrate on learning workflow and procedures/techniques. Controls are all slightly different, and machine tool builders are as well even with the same control. Just think of it more like driving different cars where the buttons are all a bit different, but the car works the same.

    You will need to supplement an education at a tech school around here in order to learn more modern techniques. With all due respect, they are designed to turn out drones for tool and die apprentice programs more than anything else. Youtube and forums like this are perfect places to soak up additional information and apply it to what you learn in class.

    Yes, they are true CNCs. Not high end as far as Fanuc goes, but very capable for a small simple machine like the KE-55.

    I would take one of these over any Haas if for no other reason that 10 or 15 years from now you will still have parts support for the Fanuc. Not likely with Haas.
