Abstract
Provided is a control device for a wire spark erosion machine, the control device controlling a drive trajectory of an electrode, a machining speed, and an electrical discharge frequency, the control device including a storage device and a computation device. The storage device stores at least one of data selected from an inter-electrode average voltage, the electrical discharge frequency, the machining speed, and the drive trajectory in an (n−1)-th machining, where n is an integer of two or more. The computation device calculates an inter-electrode distance in an n-th machining using a calculation model indicating a relationship between the data in the (n−1)-th machining and a machining shape of the workpiece, and computes, from the inter-electrode distance, at least one command value selected from the machining speed, the electrical discharge frequency, and the drive trajectory in the n-th machining.
