If you look at the structure of a program cnc, What comes to your mind? Can you know how to read the program. Here I will explain my little knowledge about the structure of the program cnc.

O0001
N005 G97 S250 M03
N010 T0101
N015 G00 X2.875 Z.1 M08
N020 G01 Z-2.0 F.008
N025 X3.1
N030 G00 X8.0 Z3.0 M09
