Abstract
A display method for a numerical control apparatus for simulating a machining by an animated display of such objects as a material shape, tool shape, or the like on a display screen, based on control information obtained from the numerical control apparatuses. For some actual machine tools, for example, only a tool is moved by the servo axis, or both a tool and a material are moved by the servo axes. Any one of a material shape (2) and a tool shape (3) to be moved is, therefore, specified and displayed on the display screen (1) of the numerical control apparatus so that the machining simulation is in accordance with the actual movements of the machine tools.
Claims6
A display method for a numerical control apparatus for simulating machining by an animated display, comprising the steps of:
- (a) displaying a material shape and a tool shape on a display screen, based on control information obtained from the numerical control apparatus:
- (b) arbitrarily specifying either of the material shape and the tool shape to be shifted on the display screen in a direction corresponding to a servo axis;
- and
- (c) repeating step (a) to indicate movement in dependence upon said specifying in step (b).
A method of simulating numerical control machining of a workpiece by a tool, comprises the steps of:
- (a) storing an axial allocation table indicating which of the tool and the workpiece is capable of movement corresponding to each servo axis;
- and
- (b) simulating machining of the workpiece by the tool by displaying animated movement of the tool and the workpiece in dependence upon the axial allocation table.
A method of simulating numerical control machining of a workpiece, comprising the steps of:
- (a) receiving numerical control commands from a machining program;
- (b) determining whether each numerical control command instructs movement of the workpiece other than rotational movement;
- and
- (c) displaying movement of the workpiece on a display screen in dependence upon each numerical control command determined in step (b) as instructing non-rotational movement of the workpiece.
