Up to now, the speed of the CMM axes had to be increased in order to shorten the measuring time for conventional measuring tasks with styli. The "Head Touch" method of the PH20 minimizes dynamic CMM errors at high measuring speeds. The unique "Head Touch" method (head probing) of the PH20 system enables the acquisition of measuring points by moving the measuring head and not the CMM structure. Points are captured faster and with greater precision and improved repeatability. In addition, time-consuming indexing of the head is no longer necessary thanks to the 5-axis movement. Together, these speed increases typically result in a measurement throughput that is three times higher than that of conventional systems.
