What is CNC macro programming?

CNC macro programming is a method used in computer numerical control (CNC) machining to automate and customize repetitive tasks by creating reusable code blocks known as macros. These macros allow machinists and programmers to simplify complex machining operations, reduce programming time, and improve efficiency. Macros can include variables, conditional logic, and loops, making them powerful tools for handling families of similar parts or intricate machining processes. Learning CNC macro programming can greatly enhance productivity and flexibility in a manufacturing environment.
