  • Patent number: 5173613
    Abstract: A coordinate measuring machine (10) having a three point support for a work supporting table (24) mounted over a base (12) constructed of a thermally dissimilar material. A first fixed support, (26A) and a laterally compliant second support (26B) are located at the front of the machine. The second front support (26B) is comprised of a pair of webs (28) oriented to be compliant in the lateral direction to allow relative thermal growth between the table (24) and base (12) while being rigid in the longitudinal direction to prevent rotation of the table (24) about the fixed front support (26A). Stacked crossed roller bearings (38A, 38B) provide a frictionless third point of support at the rear of the table (24).
