Abstract: A thermal compensation control system for a machine tool having a milling cutter and a cutter driver includes a tool setting probe, a temperature sensor, a workpiece touch probe, and a controller. The cutter driver is connected to the milling cutter to drive the milling cutter to process the work piece based on a control signal. The tool setting probe is configured to detect a cutter length of the milling cutter. The temperature sensor is configured to sense a measured temperature of the cutter driver or the milling cutter. The workpiece touch probe is configured to measure processing errors of the processed work piece. The controller is configured to generate the control signal based on a processing instruction, a temperature compensation model, the cutter length, and the measured temperature. The controller is further configured to determine whether to modify the temperature compensation model based on the processing errors.

Abstract: A monitoring method and a monitoring system for a machine tool to machine a workpiece are provided. The monitoring method includes the following steps. First, a vibration signal of a spindle of the machine tool is detected. Next, a vibration feature value of the vibration signal is obtained. Whether the vibration feature value exceeds a threshold condition is determined, wherein the threshold condition is determined by a training model based on a predetermined surface quality of the workpiece. When the vibration feature value exceeds the threshold condition, a machining parameter of the machine tool is adjusted.

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.
