Claim Text:
1. A coordinate measuring apparatus for measuring a workpiece having a workpiece surface, the coordinate measuring apparatus comprising: a sensor configured to capture the workpiece surface of said workpiece; a mechanism configured to move said sensor in at least one coordinate direction (x, y, z) relative to the workpiece, said mechanism including a rigid frame, a mount, and a measuring skid; said rigid frame including a first horizontal longitudinal member having a first horizontal guide, a second horizontal longitudinal member having a second horizontal guide; said second horizontal guide being arranged parallel to and in a spaced relationship to said first horizontal guide; said rigid frame further including at least a first vertical support, a second vertical support, a third vertical support and a fourth vertical support each having a respective upper end and a respective lower end; said first horizontal longitudinal member being rigidly connected to said upper ends of said first and second vertical supports; said second horizontal longitudinal member being rigidly connected to said upper ends of said third and fourth vertical supports; said rigid frame further including a first and a second transverse member; said first transverse member being oriented transverse to the longitudinal direction of said first horizontal longitudinal member and to the longitudinal direction of said second horizontal longitudinal member and being rigidly connected to said lower end of said first vertical support and to said lower end of said third vertical support; said second transverse member being oriented transverse to the longitudinal direction of said first horizontal longitudinal member and the longitudinal direction of said second horizontal longitudinal member and being rigidly connected to said lower end of said second vertical support and said lower end of said fourth vertical support; said first transverse member and said second transverse member of said rigid frame being spaced apart from one another and being supported via said mount on a frame support; and, said measuring skid being configured to move said sensor in a first horizontal coordinate direction (x) along said first horizontal guide and said second horizontal guide.
