示す。 Fig. 1 is a block diagram showing a numerical control device according to an embodiment of this invention, Fig. 2 is a diagram showing an example of the return-to-origin operation by the numerical control device according to an embodiment of this invention, and Fig. 3 is a diagram showing a conventional numerical control device. FIG. 4 is a block diagram showing the control device, and is a diagram showing an example of the operation of the intermediate point return type return to origin using a conventional numerical control device. In the figure, 2a is an arithmetic unit, 7 is an axis data distribution device, and 8 is an origin return axis priority storage memory. Note that the same reference numerals in the figures indicate the same or corresponding parts.

Claims

[Scope of utility model registration request]

In a numerical control device that drives a plurality of axes to numerically control a mechanical device, the amount of movement of the plurality of axes to the origin is determined by inputting a home return command to return the plurality of axes to the origin of the mechanical device. a calculation device that calculates the movement, a home return axis priority storage memory that stores in advance which axis among the plurality of axes is to be driven with priority over other axes during the home return operation, and a movement calculated by the calculation device and an axis data distribution device that outputs the quantity according to the priorities stored in the origin return axis priority storage memory.
