Abstract: An apparatus for electrical discharge machining modulation control includes an EDM module, an open-circuit voltage modulation module, a reference-voltage modulation and judgment module, a database, and a control unit. The control unit selects a reference voltage, and an open-circuit voltage corresponding to characteristics of a workpiece from the database, and generates and transmits a second control signal to the open-circuit voltage modulation module for modulating the open-circuit voltage, and a third control signal to the reference-voltage modulation and judgment module for modulating the reference voltage utilized to determine if the ignition happened. The open-circuit voltage modulation module receives a first control signal periodically transmitted from the control unit for providing the open-circuit voltage to the EDM module. The reference-voltage modulation and judgment module performs an arc voltage measurement procedure, then the control unit determines the open-circuit voltage and the reference voltage.

Abstract: A motion control system and a motion control method are provided. The motion control method includes: sending a plurality of machining commands to a second controller by a first controller at a cloud; storing the plurality of machining commands in a buffer by the second controller; and operating the machine tool according to the plurality of machining commands stored in the buffer. As such, when poor communication occurs between the first controller and the second controller, the second controller causes the buffer to send a deceleration command to the machine tool so as to cause the machine tool to operate at a reduced speed, thereby avoiding unexpected motion such as sudden shutdown of the machine tool and damage to machined products.
