The basic operation procedure of a CNC milling machine typically includes powering on, returning to the reference point, program input, workpiece clamping, tool setting, machining, and powering off. Safety operating procedures must be followed during operation, such as wearing appropriate protective gear and correctly using the emergency stop button. The CNC system control panel usually consists of a CRT monitor, an MDI panel, and a machine tool control panel. Programming is an essential skill for operating a CNC milling machine, involving both manual and automatic programming.
The selection of cutting parameters must follow certain principles: roughing aims for high metal removal rates, while finishing aims for high surface quality. Key parameters such as cutting speed Vc and table feed rate F can be calculated using formulas.
