5-Axis CMM Techniques

Technique:  Head Touches

HEAD TOUCHES is a 5-axis CMM touch-trigger probing technique available from Verisurf in conjunction with the Renishaw PH20 and REVO head systems. For measured features requiring position and size, discrete points are captured utilizing the performance of the 5-axis system or in combination with the XYZ axes of the CMM. It’s an ideal technique when minimum points are required but speed of measurement is important.

Unlike conventional touch-trigger measurement methods which rely on speeding up the motion of the CMM’s 3 axes to measure quickly, HEAD TOUCHES utilize head motion to minimize the dynamic errors of the CMM at higher measurement speeds. HEAD TOUCHES allow measurement points to be taken by moving only the head, rather than the CMM structure. Points can be taken faster, and with improved accuracy and repeatability.

5-axis motion eliminates time spent indexing the head. Together these speed increases typically result in a 3-fold improvement in throughput over conventional systems. Infinite positioning capability guarantees optimal feature access, minimizing stylus changes. 5-axis HEAD TOUCHES also reduce the need for special fixturing to allow access to difficult to reach part features.
