ABSTRACT:
The mounting comprises a base supporting a first rotary motor whose shaft has secured thereto a housing supporting a second rotary motor whose shaft has the stylus secured thereto. Each motor is operable optionally in a constant torque mode and a positioning mode and each motor has an angular position transducer. In use, the base is secured to the operating member of a coordinate measuring machine and the machine is driven through a path such that the free end of the stylus can maintain engagement with the surface of a workpiece under the force generated by one of the motors while that motor is in the constant torque mode. The profile of said surface is then determined as a function of the coordinate position of the operating member, the angular position and the length of the stylus.
