Milling g90, g54 What does it mean?
CNC machine tools are digital control machine (Computer numerical control machine tools) for short, is a program control system with automatic machine tools.
The coordinate system is the relative position of the workpiece in the mechanical coordinates.
G90 is absolute value programming, such as the knife is now in the X20Y0 position, G90G00X30Y0, the tool will move to the X30Y0 position.
The control system can logically process a program with control codes or other symbolic instructions and decode it, digitally represented by code, and input to the numerical control device through the information carrier.
