System and method for offsetting measurement of machine tool

摘要

A method and a system, for offsetting measurement of machine tool, includes following steps. A tool seat is chosen, a first coordinate is set based on a first datum mark of the tool seat. There is a total tool seat assembling length in between the first datum mark and the tool seat. A tool is chosen, assembled in the tool seat, and includes a total tool length. A second coordinate is set based on a second datum mark of a measuring unit. The tool seat is moved to make a machining end of the tool contact with the second coordinate to obtain a relative total length in between the first and the second coordinate. The total tool length subtracts from the relative total length equals an assembled offset length. The total tool seat assembling length subtracts from the relative total length equals and obtains a tool assembling length.

1. A method for offsetting measurement of a machine tool, comprising steps of:
choosing at least a tool seat, setting a first coordinate based on a first datum mark of the tool seat, and wherein there is a total tool seat assembling length in between the first datum mark of the tool seat and an end surface of the tool seat; choosing at least a tool, assembling the tool in the tool seat, and the tool including a total tool length; providing a measuring unit, and setting a second coordinate based on a second datum mark of the measuring unit; moving the tool seat along at least an axial direction to make a machining end of the tool contact with the second coordinate, so as to obtain a relative total length in between the first coordinate and the second coordinate in the axial direction; and subtracting the total tool length from the relative total length to obtain an assembled offset length, and subtracting the total tool seat assembling length from the relative total length to obtain a tool assembling length.
