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.
