G-code for CNC woodworking applications is the core programming language used to control CNC machines in the woodworking industry. It allows precise movement of cutting tools, ensuring accuracy, repeatability, and efficiency when producing wooden parts.
What Is G-code in CNC Woodworking?
G-code is a numerical control language that instructs CNC machines how to move, cut, drill, and carve wood materials. In CNC woodworking applications, G-code defines tool paths, spindle speed, feed rate, and cutting depth for operations such as routing, engraving, and pocketing.
Common G-code Commands Used for Woodworking
Below are commonly used G-code commands in CNC woodworking projects:
- G00 – Rapid positioning without cutting
- G01 – Linear cutting movement
- G02 / G03 – Clockwise and counterclockwise arc movements
- M03 / M05 – Spindle on and off
- F – Feed rate control for smooth wood cutting
