LEICESTER, England, Jan. 4, 2012 — Taylor Hobson has introduced a single-platform metrology instrument that performs three core measurements: roundness, form and surface finish. The Talyrond 500 series offers a solution for accurate roundness, contour and surface measurements that previously required three separate instruments, resulting in savings in both time and equipment outlays. Measurement resolution is 0.3 nm. The metrology instruments use rotary, vertical and horizontal measuring data to duplicate a machine tool’s movement to exactly reproduce the workpiece shape. This ultrahigh-precision simulation of a cutting tool path allows for accurate control of a manufacturing process. The instruments are suited for a variety of measuring applications, including precision bearings, fuel injectors, crankshafts and turbocharger parts. A range of standard and highly specialized accessories accommodate the most demanding applications. Features include a high-resolution gauge and low axis noise for linear or circumferential surface roughness measurement; a frictionless air-bearing spindle and precision column for roundness, cylindricity and straightness measurements; and a patented calibration technique for measurement of radius, angle, height, length and distance. The instruments provide high-productivity and error-free performance, regardless of operator skill, and automatically perform calibration, center and level functions along with measuring routines. Ease of operation results from simplified teach-and-learn programming techniques, comprehensive user prompts and on-screen instructions. Users can quickly rectify production issues that cause out-of-specification components. Deviations can be broken down into irregularities that have both frequency and amplitude. Harmonic analysis can identify these imperfections, allowing users to isolate and correct their cause. Noise and vibration issues typically occur on components produced on machines with alignment, balance or chatter problems. As the level of manufacturing precision increases, it has become more difficult to minimize these often subtle machine tool effects. The new system, with its frictionless air-bearing spindles and high-precision encoders, is suited for identifying and isolating high-frequency harmonics. A simple roundness measurement followed by harmonic analysis rapidly identifies these types of problems and provides information for their correction.
