This article examines the mechanical architecture of the Renishaw REVO probe head, a five-axis scanning system for coordinate measuring machines. It explains the articulated kinematic design that allows simultaneous motion in tilt (A-axis) and rotation (C-axis), the use of precision air bearings for smooth, low-friction operation, and the modular probe change ports with automated coupling for rapid sensor interchange. Together, these features enable high-speed, high-accuracy measurement of complex geometries, improving throughput and flexibility in precision metrology applications.
