Abstract

A tool setter is used to locate the cutting edges of a cutting machine tool with respect to the rotational axis of a lathe's workpiece holder. One or more machine tool detecting probes are mounted on the tool setter having their styluses in predetermined registration with the rotational axis of the workpiece holder. The machine tool is moved into contact with the styluses so that the location of the cutting edges of the machine tool relative to the rotational axis may be calculated. Once the precise location of the machine tool is known, the path the machine tool is required to traverse may be accurately calculated for machining the workpiece. The tool setter is removed from the workpiece holder prior to securing a workpiece to prevent contamination from spewn cutting chips and cutting oil during the machining process. The tool setter is provided with an alignment assembly to repeatedly and accurately position the styluses at the same predetermined registration locations during each mounting of the tool setter to the workpiece holder.
