摘要： A robot arm processing system includes a robot arm, a processing module, and a control module. The robot arm is for providing a mechanical holding force. The processing module is disposed on the robot arm to process a workpiece. The control module is connected to the robot arm or the processing module. The control module outputs an anti-vibration signal according to the reaction force of the workpiece or the displacement of the robot arm to counteract the reaction force of the workpiece or the displacement of the robot arm.

摘要： A machining parameter adjustment system is established in a controller. The controller is connected to a machine. The controller is configured to receive a machining program and analyze at least one process included in the machining program. Also, the controller sets a tuning program corresponding to the process and inserts the tuning program before or after the code of the process, so as to generate an integration program and upload the integration program to the machine.

摘要： A method for adjusting a frequency response parameter of a machine tool and a system using the same are provided. The method includes the following steps. Firstly, an actual frequency sweep is performed on the machine tool to acquire an original system closed loop data of the machine tool. Then, an original system open loop transfer function of the original system closed loop data is acquired. Then, a speed optimization procedure is executed to determine an optimized speed parameter. Then, a speed optimized open loop transfer function corresponding to a speed optimized close loop transfer function is acquired. Then, a filter transfer function of a filter is determined. Then, a filter optimization procedure is executed.

摘要： A non-contact dynamic stiffness measurement system includes a base, a test bar, an exciter, a force sensor, a laser Doppler velocimeter, and a controller. The force sensor is connected to the exciter and the base. The exciter is located between the test bar and the force sensor. The controller is electrically connected to the force sensor and the laser Doppler velocimeter. The test bar is detachably set in a holder of the main shaft under test. The exciter provides an electromagnetic force to the test bar. The force sensor measures the acting force of the exciter. The laser Doppler velocimeter provides a first laser beam and a second laser beam. The laser Doppler velocimeter measures a vibration response with reflected laser beams. The controller determines an equivalent main shaft stiffness value of the main shaft under test according to the acting force and the vibration response.

摘要： A processing method for automatically generating machining features is provided. A workpiece CAD file is obtained to perform a CAD numerical analysis on a blank body. With the workpiece CAD file being used as a target, a workpiece CAD appearance is compared with the blank body to obtain a feature identification result of a first to-be-processed blank body, which includes identifying data of a to-be-removed blank body and a feature of a first processing surface. A geometric analysis is performed on the first processing surface feature and a tool selection range is determined. A virtual cutting simulation is performed on the first processing surface to generate a processed area data and an unprocessed area data. A spatial coordinate mapping comparison between the unprocessed area data and a surface data of the workpiece CAD file is performed to obtain a feature identification result of a second to-be-processed blank body.

摘要： A drilling system including a feed control module, a force control module, a hole breaking control module, a conversion module and a computing unit is provided. The feed control module sets a feed force threshold and a feed speed threshold for the computing unit to determine whether the current mode satisfies a first conversion condition. The hole breaking control module sets a drilling penetration force threshold and a drilling penetration speed threshold for the computing unit to determine whether the current mode satisfies a second conversion condition. The conversion module informs to change the feed force and the feed speed according to the determination results of the two conversion conditions. The force control module provides the feed force. With the drilling system, possible impact on the workpiece due to resistance change which occurs when the drill just touches and nearly gets through the workpiece will be reduced.
