Conventional milling machines typically feature a moveable tabletop (or clamping device) that holds the workpiece in place, allowing machine operators to move the workpiece in different directions against the rotating cutter.
Like the conventional milling machines, CNC milling machines also rely on a moveable tabletop and rotating cutters to remove materials and create parts. However, they differ in the mode by which these machining operations are carried out.
CNC milling machines use computerized controls to carry out machining operations, whereas conventional milling requires manual operation of the rotating cutter to create parts.
