Measurement is an essential part of manufacturing, used to control processes and verify products. However, measurement time is often viewed as non-productive, causing unwanted bottlenecks and putting pressure on manufacturers’ operating margins.
Renishaw’s 5-axis measurement product range for co-ordinate measuring machines (CMMs) claims to be one of the biggest step-changes in measurement capability ever introduced in industrial metrology and goes a long way to overcoming these challenges.
The need to retain accuracy has historically compromised the ultimate speed of the measuring process due to the characteristics of a CMM’s structure. The non linear motion of a Cartesian CMM induces accelerations and decelerations that twist and deflect the machine structure, and result in measurement errors that increase with speed and acceleration.
CMM manufacturers work relentlessly on software and machine improvements to overcome those limitations, but ultimately the physical nature of the CMM structure constrains further improvement. REVO® 5-axis systems approach this challenge from an entirely different perspective, minimising CMM accelerations whilst moving the stylus very rapidly over the component surface through the simultaneous control of the three machine and two probe head axes (X, Y, Z and A, B).
Additionally, the REVO® system offers five different probe families, each specifically designed to maximise the advantages of 5-axis motion and infinite positioning. The probes are automatically interchangeable and include tactile scanning, touch-trigger, surface finish and non-contact vision probes. All are used within a common co-ordinate reference frame and provide the choice of an optimum tool to measure multiple features all on a single CMM platform.
Automotive is one sector benefitting from this technology with manufacturers finding unparalleled advantages in the expanded SFP2 surface finish measurement product range, offering operator independent data collection and the opportunity to eliminate dedicated surface finish equipment. By integrating automated roughness measurement and drastically reducing the number of probe styli required to measure complex parts, REVO® systems have a direct impact on powertrain manufacturing effectiveness.
