CNC Programming: Sequence, Formats, Codes, and Words

CNC (Computer Numerical Control) programming is the language used to instruct CNC machines to perform specific operations. It involves a detailed sequence of instructions written in a specific format, utilizing various codes and words to define the machining process.

Sequence of a CNC Program

A typical CNC program follows a logical sequence to ensure safe and accurate machining. While the exact order can vary depending on the complexity of the part and the machine, a general sequence includes:

  1. Program Start: Usually indicated by a specific character like "%" or a program number (e.g., O1234).

CNC program transfer through electronic media.

The transfer of CNC (Computer Numerical Control) programs to machines through electronic media is a critical aspect of modern manufacturing, enabling efficiency, accuracy, and automation. Over the years, various electronic methods have evolved, each with its own advantages and applications.   Here are the primary means of CNC program transfer through electronic media: 1. RS-232 Serial Communication (DNC - Direct Numerical Control) The RS-232 serial interface is historically the most common method for connecting CNC machines to external devices, such as computers. Functionality: Program Transfer: CNC programs (G-code) are sent character by character over a serial cable (typically a DB9 or DB25 connector). Drip Feeding: For older CNC machines with limited internal memory, RS-232 is used for "drip feeding" or "Direct Numerical Control (DNC)." In this mode, the program is stored on a computer, and blocks of the program are sent to the CNC machine's buffer as...
