Abstract
A method for evaluating tool health with the temperature rising signal, applied to a machine tool that utilizes a tool to perform a removal process upon a workpiece, comprises the steps of: setting a target machining instruction; utilizing a processor to divide the target machining instruction into a residual machining instruction and a micro machining instruction; performing the residual machining instruction; without any coolant or with little coolant, performing the micro machining instruction, and having at least one thermal image sensor to detect a thermal image of a contact area of the tool and the workpiece; having the processor to derive a temperature feature by evaluating the thermal image; and, having the processor to compare the temperature feature with at least one threshold for determining the tool health.
