Re: Trying to load programs onto U100L dual spindle/ turret Okuma lathe.
Ok, where to start...you need to go into MS DOS mode when working with DOS disks. This is done by pressing the extend button until MS-DOS shows up in edit mode. Press that and then you can read and write to dos disks. Otherwise it will want to use Okuma format disks and you do not need to go into MS-DOS mode. Dos is limited to 8 character file names with only alpha-numeric names. Okuma requires that they start with a letter, but NOT "O" as they are a sub callout name such as OSUB1.SUB. Okuma files can have up to to 16 character files names. You have several file types: MIN is main program, SUB is for Sub-programs, SDF is for a Schedule Data File (for calling main programs in sequence), SSB System Sub programs (which load on startup), and MSB which are manufacturer sub programs (for gauging, etc. also loaded on startup) To run on the Okuma you primarily want to use MIN files. They are just a plain text files like from notepad only with the MIN extension rather than TXT. ABC123.MIN would be a good file name in either system.
Next, your Fanuc guy will have little experience with Okuma as it is a different animal. Much better in many ways...once you get to know it...very powerful control. Be patient, because there are usually 3 ways to do anything on it. None wrong and you'll find it makes much more logical sense on operation with tons of little "help" functions.
Next, which machine are you trying to program? I have sample code for many Okumas and Twin Spindle twin turret machines are my specialty, so I've probably got a good "template" for you to work from. I also have a few helpful subs for working with load monitor and for checking switches that you may find helpful.
Experience is what you get just after you needed it.
