G code decoding program of small CNC engraving machine

Decoding is the standard of small CNC engraving machine nc code translation into system can identify the code form. After the user input G instructions in accordance with the requirements, the system first to instructions given wrong, such as there is no wrong input, entered the stage of decoding, decoding process using piecewise read, piecewise processing method, the piecewise call. Below is the program flow diagram.
