Abstract
Graphics representing a main-spindle-side structure and a table-side structure and graphics representing arrows indicating the movement directions of feed shafts are stored in a storage unit, and when switched to manual operation, a display computation unit computes the orientations of said arrows with respect to the structure that moves, said structure being either the main-spindle-side structure or the table-side structure, and computed graphics representing the structures and the arrows are displayed in a differentiated manner so as to make it evident which structure moves.
Claims6
A control device for a machine tool for operating the machine tool by an NC program or moving commands generated by a manual operation, characterized by comprising:
- an input section having switching means for switching between an NC program operation mode and a manual operation mode, coordinate system mode selecting means for selecting the coordinates system of the feed axes or feed control function, and moving command generating means for generating moving commands by a manual operation;
- a storage section for storing graphics of the spindle side structure and the table side structure of the machine tool and arrows indicating the moving direction of the feed axis;
- a display calculating section adapted to receive the graphics of the structures from the storage section and to calculate the direction of an arrow relative to one of the spindle side structure and the table side structure to be moved depending on the coordinate system selected by the coordinate system mode selecting means or on the feed control function when the switching means of the input section is switched to the manual operation mode;
- and
- a displaying section for displaying the graphics of the structure and the arrow calculated by the display calculating section.
