Abstract
A coordinate measuring machine (10) having a light weight aluminum bridge (24) mounted for guided movement along ways (42) on a base (28), which also is constructed of aluminum to match thermal growth characteristics of the bridge (24). The table (12) is constructed of steel for greater rigidity to support heavy measured objects (1b) and is supported on the base (28) so as to minimize distortions of the base (28) by differences in thermal growth of the table (12), and base (28). The weight of the table (12) and measured object (16) is arranged to be passed through the base (12) to floor supports (62, 112) to minimize distortions of the base (12) and ways (42). The bridge (24) is movable completely to the rear of the table (12) to enable access of the probe (18) to the total table surface area FIG. 2.
