Abstract: A process diagnosis system includes a digital twin calculation unit, a process diagnosis calculation unit, and a remote calculation analysis unit. The digital twin calculation unit obtains a vibration-related parameter and a cutting-related parameter of a processing device, and performs a simulation calculation for the vibration-related parameter, the cutting-related parameter and a three-dimensional model corresponding to the processing device to generate a three-dimensional calculation result. The process diagnosis calculation unit receives a three-dimensional calculation result and displays the three-dimensional calculation result. The remote calculation analysis unit receives the three-dimensional calculation result, and performs a simulation analysis for the three-dimensional calculation result to generate an analysis result.

Abstract: A detection device for a spindle of a machine tool is provided, wherein the spindle includes an insertion hole. The detection device includes a contact housing, a main housing, a sensor, and a process module. The contact housing has a first chamber, and the first chamber has an inner surface. The main housing is connected to the contact housing, and has a second chamber communicated with the first chamber. The sensor is disposed in the first chamber and connected to the inner surface. The process module is disposed in the second chamber and electrically connected to the sensor. When the contact housing is inserted into the insertion hole of the spindle, the sensor is configured to detect the deformation of the contact housing and generate a detection signal. The process module generates a determination signal according to the detection signal.

Abstract: The invention provides a working trough and a method for maintaining a uniform temperature of a working fluid. The working trough is applied to an electrical discharge machine that performs wire cutting using the working fluid. The method for maintaining a uniform temperature of the working fluid is applied to the working trough and characterized by forming opening structures in a receiving slot of the working trough such that a spiral swirl having a predetermined height is allowed to be formed in the working fluid, thereby maintaining a uniform temperature of the working fluid in the receiving slot when a wire cutting process is performed in the working fluid by the electrical discharge machine. The disturbance of the spiral swirl also facilitates the discharge of scraps. The present invention further has an advantage of low cost.

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 hydrostatic rail guide includes a guide rail, a guide carriage, a hydrostatic supply device, a measurement device and a controller. The guide carriage is hydrostatically mounted on the guide rail and has a hydrostatic channel filled with oil. The oil keeps the guide carriage and the guide rail at a gap. The hydrostatic supply device is adapted for supplying the oil to the hydrostatic channel and adjusting the pressure of the oil. The measurement device is installed on the guide carriage and adapted for detecting the gap between the guide carriage and the guide rail and for producing a distance signal of the measured gap. The controller is connected to the hydrostatic supply device and the measurement device. The controller is adapted for controlling the hydrostatic supply device, based on the distance signal, in order to adjust the hydrostatic pressure of the oil after being pressurized.
