Abstract: A display method includes: converting, by a fitting unit, a position information into a fitting parameter; constructing, by the fitting unit, a first pattern from the position information; constructing, by the fitting unit, a second pattern from the fitting parameter; calculating, by a calculation unit, an offset information between the first pattern and the second pattern; integrating, by an integration unit, the fitting parameter of the fitting unit and the offset information of the calculation unit into a reference information; and constructing, by the integration unit, a third pattern from the reference information. In a human-machine interface applying the display method, when a user enters an amount of tolerance into the human machine interface, the machining path represented by the third pattern is reproduced on the human machine interface. Thus, the display method can simplify operations of processing the machining path and reduce the load on the memory.

Abstract: A method for monitoring cutting-tool abrasion of a machine tool includes the steps of: defining a tolerance range of abrasion of a cutting tool; collecting loading data of the cutting tool at every continuous machining sections; extracting actual-cutting loading data from all the loading data; calculating coefficients of fitting lines of the loading data for individual machining sections according to the actual-cutting loading data; comparing the abrasion of the cutting tool according to the tolerance range and the fitted lines; and, if an outranged result occurs, issuing an alert message to adjust or to replace the cutting tool.
