Unlike conventional scanning methods, which rely on speeding up the motion of the co-ordinate measuring machine's (CMM's) three axes in order to scan quickly, 
5-axis scanning uses synchronised motion of machine and head axes to minimise the dynamic errors of co-ordinate measuring machine (CMM) motion at ultra-high scanning speeds. Up to 500 mm/s is possible without any loss in accuracy.

REVO™
REVO™ is a dynamic new measuring head and probe system from Renishaw. A revolutionary new product designed to maximise CMM throughput whilst maintaining high system accuracy.

Renscan5™ Explained
Renscan5™ technology uses 5-axis scanning to minimise the dynamic errors caused by the inertial forces that affect the moving mass of the CMM structure. When a 5-axis measuring system is used, most of the unwanted CMM dynamic error is removed because the measuring head performs the majority of the work.

As the head is much lighter and more dynamic than the CMM, with a significantly better frequency response, it is able to quickly follow changes in the part geometry without introducing harmful dynamic errors. This allows the CMM to do what it is best designed to do - move at constant velocity in a single vector while measuring.
