Abstract: An automated contact gage system for gaging a workpiece or device has a left spindle, a right spindle and a stylus arm for contacting the workpiece or device in the same Y plane as the probe. A bearing arrangement is used to contact the stylus arm so as to guide and support the stylus arm during contact gaging of the device. The bearing arrangement comprises a spherical race, derived from three spherical elements, contacting a bearing so as to provide for multi-dimensional movement and measurement of movement of the stylus arm. First, and second sensors sense and measure movement of the stylus arm and/or workpiece in two dimensions, while a third sensor senses and measures rotation of the workpiece by the right spindle.
