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 bracket positioned on one side of a membrane or surface is adjustable from the other side of the surface to permit the position of an item supported by the bracket to be readily adjusted relatively to the surface. The bracket has a base to which an arm is movably attached. The arm moves between an open and a closed position to permit the item to be received by the bracket. In the closed position the item is clamped between the base and the arm. A finger is mounted on the base and is movable into and out of engagement with a contact surface on the arm. When the finger engages the contact surface it secures the arm in the closed position and effects the clamping action which holds the item in position. The finger and arm are readily accessible to permit adjustment.

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.

Abstract: An interference preventing method applied on a machining machine includes the following steps. Firstly, a control command is provided in response to an operation event. Next, protection information corresponding to a protection target component is provided. Then basic envelop of the protection target component is obtained. Then the basic envelop is segmented into a number of sub protection blocks according to a multi-hierarchical protection parameter and sub protection blocks not linked with the protection target component are removed, so as to determine a multi-hierarchical interference protection area. Next, whether an interference event of the multi-hierarchical interference protection area and other components occurs, so as to determine whether interference event of the protection target component occurs; if so, control signal is provided to control the processing operation of the machining machine.

Abstract: Extra coagulant is added to the cuff portion of the former by a spray nozzle located between the coagulant and latex dipping tanks. A former is placed into a coagulant. After removal from the coagulant, additional coagulant to the cuff portion of the former by any conventional means, such as a spray nozzle. The higher concentration of coagulant at the cuff portion results in a thicker latex thickness at the cuff portion and counteracts the reduced dwell time of the cuff in the latex dipping tank as compared to the fingertip portion of the former. The thickness of the cuff portion can be controlled by altering the concentration of the coagulant applied by the spray nozzle.

Abstract: A dual-receiving ultrasonic distance measuring equipment is disclosed, which uses a transmitter and two receivers, one of which serves as an objective and the other as a reference, to perform distance measurement. The transmitter and the reference receiver are fixedly installed on a phase adjusting platform, capable of adjusting a reference phase by fine-tuning the distance between the transmitter and the reference receiver. As the objective receiver is disposed on an object under measurement which is a distance away from the phase adjusting platform, there will be a phase shift due to the propagation of an ultrasonic wave from the transmitter as it is received by the two receivers. And thereby, the distance between the two receivers can be calculated based on the phase shift. The aforesaid ultrasonic distance measuring equipment can be applied in the positioning system of high precision machinery or other non-contact distance measuring system.
