Abstract:
1. A precision video gauging machine system for measuring a workpiece comprising: a base; a carriage for supporting the workpiece to be measured, vertically movable with respect to said base; a carriage feed mechanism for moving the workpiece supported on said carriage including a rotatable knob mounted by linkage to the carriage and selectively driving a drive member in frictional engagement with said carriage, whereby when said knob is rotated, the linkage drives said drive member to move said carriage and supported workpiece vertically with respect to said base in a direction based upon the direction of rotation; a carriage lock mechanism for selectively coupling and decoupling said carriage feed mechanism to said carriage; a column, horizontally movable with respect to said base; a video based coordinate measuring system for measuring the position of a video camera based on a coordinate measuring system, mounted on said column comprising:
