@Rubbernecker I would say a little bit of both. We used to keep cheat sheets at the machine that would have what was a functional program written in black and white. Then by using an existing written program in the control one could easily adapt that program to what your new part requires. The nature of most cnc programs is that there are a lot of start up sequences that have to be included in an exact manner or the machine just will not even start. No problem with it crashing because it was showing an error code before the spindle came on or any slides were even moving. That's where the cheat sheet was handy because you could go from the very beginning of your new program and compare to what was written on the cheat sheet to determine where the mistake was made. But for the most part all you had to do was change the starting size and then the geometry of what you want to end up with, that was what was in your g71 line. G70 being the roughing cycle and g71 being the finish cycle. G72 and g73 were the boring settings for the turned part.
I was gunna say, this guy must be a boss level haha, Because I only know certain codes. But not how to design the code program needed fit from scratch. Lol, that's dope!. I use to run a Haas VF2 for a couple of years. Fun gig.
Wow VTLs have came a Long Long way from the 1948 Do'ories VTL I worked around 20yrs ago , these are Way more faster & efficient than WW2 technology ! Thanks
That 21i-TB should have Fanuc’s first version of Manual Guide I installed or at least have the option for it. But seeing that the colors have been switched up using the parameters and you have memorized the “shift” key for typing code, no amount of proof showing its capabilities has ever made me be able to convert the “old school” crowd. It’s first version was super capable but lacked peck grooving cycles for chip evacuation. Either way, with the implementation of some simple macro b you can create your own canned peck grooving cycles and so much more, plus have 3d simulations on that screen giving you real time feedback of what the controller is going to do all while displaying the actual position values and tool geometry. And it had crash detection. Also it will simulate traditional g-code program showing you potential errors in that code as well.
Good job. I do have one question as to why on the jaws of the machine did you not put some kind of insert so when you clamped down the product it didn’t gouge or put gouges where the clamps tighten down on the project so that you don’t have those gouges? Is that not something you’re worried about at all because you want to redo it over again or what?
Toolpath simulation available, on that Fanuc? Otherwise I find it rather scary, to run hand g-code directly, especially on such a monster machine. My old Fanuc3T sucks particularly hard in that regard, if you forget a "." it thinks 0.001mm instead of mm ;-/
We didn't even have tool changers on our cnc lathes. Cutting 4 inch diameter S7 we could only take a little more than the tool nose radius for a depth of cut so our cycle times were pretty long. Using a quick change tool holder like the Aloris brand, we would find that our tool offsets held very well as long as you didn't crash the machine. S7 was hard on the carbide so making sure that there was fresh inserts in the tool holders was key to success.
are all your machines Fanuc? After 30 years of being a fabby im learning CNC now on a Fanuc run Mill. Your videos are great because I understand the operating system
Most of the older g code / m code controls operate similarly. All of them need a little start up sequence to tell the machine what you are doing like are you working in metric or sae, which direction you want the spindle to turn , do you want coolant, etc. Once you learn and recognize those pieces of the program you can read almost any program just like a different language.
