Simple Fanuc Program Example.

There are more complicated examples on my website, including Canned Cycles and using Cutter Comp.
www.doccnc.com

Part is 2" OD, will be finish faced with OD skin cut taken.
O2001(Program number)
N1G50S2500(The G50 sets up safe max speed.)
N2T0101(Tool index to position 1, use tool offset 1 to set tool and to change part size.)
N3 G96S650M3(G96 is Constant Surface Feet, S is amount, M3 is spindle on CW.)
N4G0X2.1Z0(Rapid to above OD and face of part.)
N5G1X.5F.006(Face to .500 at a feed of .006 per rev.
N6G0X2.0Z.1(Rapid to 2" diam. and clear part on way up.)
N7G1Z-1.0F.001(Cut left at F.001.)
N8G0X6.0Z6.0(Rapid to clear for loading new part, newer controls do not need tool offset cancellation.)
N9M30( Ends program, resets memory to start.)
Usually coolant is used, M8 is on, M9 is off.
Good luck: Heinz.
