CNC machining is one of the core processes in manufacturing that produce intricate and sophisticated products that have applications in various industries. At the heart of CNC machining’s unmatched efficiency and accuracy are the G and M codes – the critical programming languages that guide CNC machines.
Unlike common perception, G codes and M codes hold distinct roles in CNC operations. G codes primarily instruct the machine on the geometry of the cut, while M codes control the hardware aspects, like turning the spindle on or off. This nuanced difference is pivotal for understanding the full potential of CNC machining.
In this article, we delve into the specifics of these codes, unraveling their unique functions and how they synergize to optimize CNC machine performance.
