Abstract
Abstract There are disclosed a method of and an apparatus for displaying a path of movement of a machine tool numerically controllable by a numerical control system (2,3) which processes machining command data supplied from an external source to produce a movement command for numerically controlling the movement of the machine tool. The method comprises the steps of converting the movement command from the numerical control system (2,3) into coordinate data on a display unit (8) during a machining mode of operation of the machine tool, and displaying a machining path of movement of the machine tool on said display unit (8) based on said coordinate data. The arrangement allows the operator to monitor on the display unit (8) how much a workpiece has been machined on the machine tool.
