Abstract

A position detector comprises a probe having an enlarged head which can be engaged with a workpiece to be machined by a machine tool. The probe is slidably mounted in a holder for rectilinear movement relative thereto along an axis and its translational displacement along this axis is measured by a transducer. The holder is in turn mounted on a body for pivotal movement about another axis, the pivotal displacement of the holder being measured by a further transducer. The two axes are mutually perpendicular and mutually intersecting. Signals produced by the two transducers when the probe engages the workpiece are converted by a numerical control system into co-ordinate values of a Cartesian co-ordinate system according to which the machine tool is moved during a machining seq
