Terms for CNC Milling Machine
Date：12-17-2024
- Spindle: The rotating part of the machine that holds the cutting tool. The spindle speed is measured in revolutions per minute (RPM) and is a critical factor in determining the cutting speed and material removal rate.
- End Mill: A common type of cutting tool used in milling machines. It has a cylindrical shape with cutting teeth on the end and sometimes on the sides as well. End mills are used for a variety of milling operations such as slot milling, contour milling, and drilling.
- 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.
- G - code: A programming language used in CNC milling 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).
