PROGRAM ZERO ON FANUC M

[mousongie]

Hi!

Im new in cnc milling.
I would like to get more details on how to assign a PROGRAM ZERO for each tool. My supervisor is doing it and every time he have to do it he's sending me away somewhere.(siss!).
I would like to stress that the shop is using a touch off method. Ijust see him the tool to the face of the job and then pressing some buttons. PLEASE HELP ME

You need some help -

Read some books defining the basic principle on which the CNC Program works ?


--Cartersian Coordinate system--Program Zero(Origin)--The NC program is written according to the Program Zero position--

I am really sorry that i cannot describe more, because it will confuse you a lot & create barriers for you.

Best route is to check out some books about CNC Program..(You can also get the info on web).

Tks

Thanks for your reply. i have a manual for tha machine but it doesnt say a lot about the tool setup. I even get a book by Peter Smid(cnc programming handbook 3) only to find out that its got nothing to do with setting. Would please refer me to one book?
Thanks

what kind of a machine? more detail
generally zero can be anywhere, tool zero?, don't u mean tool length offset?

Hi Nigjoe!

My friend you did touch the point. Im exactely talking about TOOL LENGHT OFFSET PROCEDURE for a milling machine. The tool is brought down to the face of the workpiece and then where or what do i press. Thanks in advence!

what kind of machine and controller? Fanuc 180 Mi or another specific modle? They are all similiar, have worked with several. Is your machine a flat matrix table or pod and rail? Do you change the G54 offset for different programs or always touch off your tools for every job? Could us some more detail.
