Terms for CNC Machine Tools
Date：12-17-2024
- G - code: A programming language used in CNC machining to control the geometric movement of the tool. It contains commands such as linear interpolation (G01), circular interpolation (G02, G03), and rapid traverse (G00).
- M - code: Another part of the CNC programming language that controls machine functions such as spindle on/off (M03, M05), coolant on/off (M08, M09), and tool change (M06).
- Spindle: The rotating part of the machine that holds the cutting tool (in milling machines) or the workpiece (in lathes). The spindle speed is an important parameter in machining operations.
- Feed rate: The speed at which the cutting tool moves relative to the workpiece. It is usually measured in units such as millimeters per minute and affects the quality of the machined surface and the material removal rate.
- Axis: The direction of movement of the machine tool. A 3 - axis CNC machine typically has X, Y, and Z axes, representing the horizontal, vertical, and depth directions respectively. More advanced machines may have additional axes such as A, B, and C for rotational movements.
