Field: Machine tools (Mechanical engineering)
Classification: CPC B  G | IPC B  G

Claim 4:
5. A prediction device to which one or more wire electrical discharge machines are connected, the one or more wire electrical discharge machines each being configured to perform machining on an object to be machined according to a predetermined machining condition while moving a wire electrode relatively with respect to the object to be machined along a machining path, the prediction device comprising:
one or more processors that execute computer executable instructions stored in a memory; and
a display unit which includes a screen,
wherein
the one or more processors execute the computer executable instructions to cause the prediction device:
to predict, for a predetermined consumable component constituting the wire electrical discharge machine and being consumed as the machining is performed, a predicted rate of consumption indicative of a rate of consumption indicative of a degree of consumption based on the machining condition when the wire electrode is moved relatively by a unit distance; and
to display the predicted rate of consumption of the component on the screen,

wherein
the processors cause the prediction device:
to predict the predicted rate of consumption by a model function created in advance to which the machining condition is input, and which outputs the predicted rate of consumption;
to acquire the rate of consumption of the component on a basis of an execution result of the machining;
to acquire an error between the predicted rate of consumption and the rate of consumption; and
to optimize the model function in a manner so that the error is minimized.
