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 Figure 2.

Abstract translation: 一种坐标测量机（10），其具有安装成用于沿着基座（28）上的方式（42）引导移动的重量轻的铝桥（24），所述基座（28）也由铝构成以匹配所述桥（24）的热生长特性。 工作台（12）由钢制成，具有更大的刚性以支撑重的测量物体（1b），并且支撑在基座（28）上，以便通过台（12）的热生长差异来最小化基座（28）的变形 ）和基底（28）。 桌子（12）和测量对象（16）的重量被布置成通过基座（12）穿过地板支撑件（62,112），以最小化底座（12）和路线（42）的失真。 桥（24）可完全移动到工作台（12）的后部，以使探针（18）能够接近整个工作台表面区域。
