Coordinate measuring machine for measuring workpiece, has drive unit that exerts directed force on thrust unit, such that amount, direction and point of application can be chosen and torque acting on measuring unit is specific value

摘要

The machine (24) has sensor (5) that detects coordinates of workpiece (7) in coordinate direction (y) by moving self-propelled drive unit (11). The drive unit and movable measuring unit (2) are formed as portals/bridges, such that measuring table (1) is spanned. The drive unit has thrust unit (15) that is moved in coordinate direction (x). The drive unit for moving measuring unit on center of gravity of measuring unit exerts directed force on thrust unit, such that amount, direction and point of application can be chosen and torque acting on measuring unit is less than 5 nm. An independent claim is included for a method of moving a measuring unit of a coordinate measuring machine via measuring table.
