This Safety Block consists of G-Codes that establish the type of coordinate system used (G90 Absolute or G91 Incremental), establishes the measurement system used (G20 inch or G21 metric), cancellation of all canned cycles (G80), cancellation of cutter diameter compensation (G40. Referring to the observation of the Tool Nose Radius not being cancelled, G41/G42 is recognized when executing a G71 cycle by late model Fanuc controls; not the case with early models. Block N10 is called the Safety Block; the name refers to its role in the program. Learn how the CNC lathe will run your tool path using any size TOOL NOSE RADIUS with the G41 and G42 command.
