Abstract
A tool presetter and a tool offset amount calculation method are provided which ensure easy and accurate determination of reference tool offset amounts in a machine tool having a pivotal tool spindle stock. The tool presetter is mounted in a composite lathe having a pivotal tool spindle stock The tool presetter calculates tool offset amounts Oz (=A−Zm), Ox (=B−Xm) on the basis of machine coordinate values Zm, Xm of the tool spindle stock detected when a nose of a tool T is in contact with Z-axis and X-axis detection points of a presetter sensor with the tool spindle stock pivoted by a pivot angle &agr;, and machine coordinate values A, B of the Z-axis and X-axis detection points of the presetter sensor , and calculates reference tool offset amounts Lz, Lx from predetermined expressions on the basis of the tool offset amounts Ox, Oz and the pivot angle &agr; of the tool spindle stock
