 | 5-axis systemsA measurement revolution! Unlike conventional CMM measurement methods, Renishaw's 5-axis technology uses synchronised motion of CMM and head axes to minimise the machine's dynamic errors at ultra-high measuring speeds.
Renscan5™ 5-axis scanning technology 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. Head touch and 5-axis touch trigger measuring technology Intelligent head technology affords rapid touch-trigger measurement by using 'head-touches' where measurement points are taken by moving only the head rather than the CMM structure. Using only the rapid rotary motion of the head, points can be taken faster, and with improved accuracy and repeatability. Renscan5 explained
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.
5-axis touch trigger measurement – Use your head! It's infinitely betterUnlike conventional touch-trigger measurement methods which rely on speeding up the motion of the CMM's 3 axes to measure quickly, PH20 utilises the head motion technology developed for the multi-award winning REVO system to minimise the dynamic errors of the CMM at higher measurement speeds. Intelligent head technology affords rapid touch-trigger measurement by using 'head-touches' where measurement points are taken by moving only the head rather than the CMM structure. Using only the rapid rotary motion of the head, points can be taken faster, and with improved accuracy and repeatability. Request a CD5-axis measuring technology in action. Request a Renscan5 CD.

Welcome to a measurement revolution, the biggest step-change in measurement capability that Renishaw has ever introduced. Whether scanning or touch-trigger measurement Renishaw's 5-axis measuring technology breaks through the limits imposed by the CMM machine and achieves unprecedented levels of throughput whilst maintaining current levels of metrology.
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.
