Coordinate measuring machine |
摘要 |
A coordinate measuring machine (CMM) is disclosed having improved manufacturability and low cost while maintaining high performance standards. The CMM includes a polymer composite gantry-style base incorporating a three-point support configuration in the X, Y, and Z axes. The X-beam is hollow, has a horizontal cross-sectional orientation, uses a passive ventilation technique, and is attached to the bearing at one end by a compliant mount. The Z-axis probe shaft incorporates a combined counterbalance/drive assembly and a compliant secondary rail guide mechanism. The X-axis and Y-axis drive screws have angular alignment capability using a spherical washer configuration. This combination of features serves to minimize non-repeatable errors and enhance the manufacturability of the CMM, providing substantial improvements in CMM design and construction.
