<p>An instrument and method for measuring a peripheral contour of a cylindrical-form, helically threaded workpiece (14) wherein the workpiece is mounted for rotation about its longitudinal axis and a measuring stylus (34) contacts the periphery of the workpiece so as to be able to move both parallel to, and perpendicularly of, the longitudinal axis of the workpiece, and as the workpiece is rotated about its longitudinal axis rotary movement of the workpiece and radial movement of the stylus as it follows a peripheral contour of the workpiece are converted to respective electrical signals representative of the angular rotational position of the workpiece and the radial position of the stylus. </p> |
