Renscan5™

A measurement revolution!

Welcome to a measurement revolution, the biggest step-change in measurement capability that Renishaw has ever introduced.

Renscan5 enables unrivalled performance and speed. Unlike conventional scanning methods 5-axis scanning uses synchronised motion of CMM and head axes to minimise the machine's dynamic errors at ultra-high scanning speeds. Up to 500 mm/s is possible without any loss in accuracy.

From 55 to 5 minutes — 900% throughput improvement
Scanning two head gasket faces and five sections in each of eight cylinder bores typically takes 50 to 55 minutes. The Renscan5 REVO^® system completes the job in 5 minutes.

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

In conventional measurement methods the CMM performs all the movements necessary to acquire the surface data. Acceleration induces inertial deflections in the machine structure, which in turn induce measurement errors.

Metrology system manufacturers have devoted years to develop techniques that reduce those dynamic errors, but there is an upper speed limit imposed by the machine and servo system stiffness, beyond which measurement cannot be taken with reliability.

Renscan5 breaks through that limit by using an articulating head that moves in two rotary axes as it measures. This allows the CMM to do what it is best designed to do - move at constant velocity in a single vector while measuring. As the head is much lighter and more dynamic than the CMM, with a significantly better bandwidth, it is able to quickly follow changes in the part geometry without introducing harmful dynamic errors, which results in much faster surface speeds and hence shorter measurement cycles.

5-axis scanning technology allows the user to achieve unprecedented levels of throughput whilst maintaining current levels of metrology.
