Abstract: A machining parameter automatic generation system includes a geometric data capturing module, a feature recognition learning network and a machining parameter learning network. The geometric data capturing module captures a geometric shape of a workpiece to generate a candidate feature list. The feature recognition learning network trains the candidate feature list according to a first neural network model to obtain an applicable feature list. The machining parameter learning network trains the applicable feature list and the candidate machining parameter according to a second neural network model to obtain an applicable machining parameter. The applicable machining parameter is used to generate a machining program, and the machining program is read by a machine tool for processing.

Abstract: A feedback control numerical machine tool and a method thereof are provided. The machine tool includes at least two spindles, an acoustic frequency detecting module, at least two spindle position detecting modules, and a control module. The spindles machine a workpiece. The acoustic frequency detecting module detects an acoustic frequency of the spindles when machining the workpiece. The spindle position detecting modules detects position information of the spindles when machining the workpiece. The control module acquires the acoustic frequency and the position information of the spindles, monitors whether any of the spindles chatters according to the acoustic frequency of the spindles, and performs chattering avoidance to the spindle that chatters according to the position information of the spindles. As such, the present disclosure performs chattering monitoring to a plurality of spindles and avoids the chattering immediately.

Abstract: A chatter avoidance method and device is provided, including steps of: providing a stable operating condition plot; partially removing a first layer of a workpiece with a predetermined first removal depth according to a safe removal depth of the stable operating condition plot and sensing a chatter caused by the removal operation; if no chatter is sensed, completing the removal operation, otherwise, continuing to partially remove the first layer with a second removal depth less than the predetermined first removal depth; and determining a minimum removal depth according to the removal operation, and removing a last layer of the workpiece with a last removal depth less than or equal to the minimum removal depth, allowing the workpiece to have a target thickness. The disclosure prevents a chatter from continuously occurring without requiring a shut-down and thereby maintains a desired production rate.

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.

Abstract: An apparatus for providing a feedback force includes a calculating unit and a force feedback displacement controller. The calculating unit receives relative position information of a first object and a second object and geometric information of the first object and the second object. If the first object and the second object are not in contact, the calculating unit calculates a force feedback value based on the relative position information and the geometric information. The force feedback displacement controller outputs a displacement command, and receives the force feedback value. The displacement command allows the first object to move with respect to the second object. The force feedback displacement controller includes a displacement unit that generates the displacement command based on an operation of a user, and a force feedback unit that provides a feedback force to the displacement unit based on the force feedback value.
