  • Patent number: 11524380
    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.
