Abstract
A load display device for a machine tool acquires machine coordinate values and load values for axes of the machine tool for each predetermined time from an axis drive control unit for drivingly controlling the machine tool. Three-dimensional coordinate values of a tool center point is calculated to obtain a tool trajectory, based on the machine coordinate values for the axes acquired for each predetermined time and information on a configuration of the machine tool. As the tool trajectory is displayed by a display device, vectors of the load values for the axes stored for each predetermined time are displayed.
Claims10
A load display device for a machine tool, in which the machine tool is configured to execute a machining program to drive axes, thereby moving a tool relative to a workpiece, and the load display device is configured to display a load on the machine tool, wherein the load display device comprises:
- a data acquisition unit configured to acquire and store machine coordinate values and load values of the axes of the machine tool for each predetermined time;
- a tool trajectory display unit configured to calculate three-dimensional coordinate values of a tool center point, based on the machine coordinate values for each predetermined time acquired by the data acquisition unit and information on a configuration of the machine tool, and display a tool trajectory;
- and
- a load display unit configured to display the load current values for the axes stored in the data acquisition unit for each said predetermined time, in the form of vectors, on the tool trajectory displayed by the tool trajectory display unit.
