Klingelnberg To Present Innovative Hybrid Gear Metrology Solutions

At CONTROL machine manufacturer Klingelnberg will be presenting its portfolio of products and services in Hall 7 – Booth 7307 which will include the Klingelnberg Precision Measuring Center P 152 for mid-sized gears, as well as the Klingelnberg Precision Measuring Centers P 26 and P 40 with optical metrology and tried-and-tested universality of application in metrology.

P 26 – Gear and Geometry Measurement

When the first generation of the Klingelnberg Precision Measuring Center P 26 was developed 25 years ago, it was impossible to foresee how much this development would ultimately shape Klingelnberg's metrology offering. Compact and tailored to the needs of the automotive industry, this precision measuring center has always been extremely popular among customers. Its 25-year success story was built on a foundation of new measurement and evaluation methods, the implementation of innovative measuring systems, and uniform quality and reliability. It is because of their accuracy and reliability that Klingelnberg Precision Measuring Centers are used as a reference around the world, not just by countless customers, but also by renowned metrology institutes.

Temperature Compensation For Hybrid Metrology

The well-established combination of tactile metrology (3D NANOSCAN) and optical metrology (HISPEED OPTOSCAN) for measuring cylindrical gears is now also available for the P26 model series.

"The P 26 precision measuring center in particular has become a fixture on the shop floor. And we’re extremely proud that we have been able to integrate not only new measuring strategies, but also temperature compensation for hybrid metrology. We now have a clear line of sight to achieving even greater reductions in measuring time in the shop-floor environment," states Dr. Kai Bartel, Director Product Line, Precision Measuring Centers.

P 40 – Hybrid Solution Reducing Production Measuring Times

Measuring times have been significantly reduced through the introduction of hybrid metrology with optical pitch measurement. It is now possible to perform optical pitch measurement on almost all surfaces using the white light sensor technology (HISPEED OPTOSCAN) developed by Klingelnberg and partners, along with other innovative measuring strategies. Two other processes for reliably measuring single pitch deviations are also available.

"With the current release, the pitch, tooth thickness, and radial run-out of gears can be measured optically on most cylindrical gears. So, depending on the number of teeth, this reduces the measuring time for a complete gear measurement by up to 40%. For pitch measurement, even greater time savings are achieved on a consistent basis," explains Holger Haybach, Head of Product Management, Precision Measuring Centers. "The measurement and evaluation are still conducted using an advanced, certified Klingelnberg cylindrical gear software that is easy to use in the way customers are accustomed to. The optical sensor extends fully automatically and positions itself according to the chosen measurement procedure, and the required measuring task is performed. The accuracy of the pitch measurement complies with the requirements of VDI/VDE 2612:2022 Class A and is therefore comparable to tactile measurements," says Haybach.

All Klingelnberg Precision Measuring Centers in the P 26 to P 65 series can be optionally retrofitted with the optical sensor. For new machines, the ‘Ready for Optic’ option is also available, providing a factory-installed setup for subsequent retrofitting. Through the systematic use of the standardized Gear Data Exchange (GDE) interface when importing and exporting data and measurement results,

Klingelnberg has set a higher standard in Metrology 4.0 in the area of measurement results diagnostics and networking of production machines and metrology – a system it calls the Closed Loop.

P 152 – Solution for mid-size gears

The increasing cost pressure on large components for wind power requires new technologies that will enable proven principles for high-volume and mass production of smaller components to be transferred over to large components. The newly developed Klingelnberg PrecisionMeasuring Center P 152 closes the gap in the portfolio between the mid-sized and the large precision measuring center model series.

The latest addition to the family is capable of measuring components with a maximum outside diameter of 1,520 mm and workpiece weights up to 8,000 kg with the usual measurement precision. Despite this heavy workpiece weight, no special foundation is required. Klingelnberg has succeeded in scaling the technology concept of the small and mid-sized series to the larger component dimensions. The inherently rigid machine bed with its 3-point support plays a key role. The bed design and floor support are cleverly designed so that even when loaded with heavy workpiece weights, the angular position of the individual machine axes to each other does not change significantly. The machine bed's 3-point support enables the integration of an active vibration platform into the machine bed. This means that even the low-frequency oscillations from the shop floor can be safely absorbed without the use of a vibration-isolating foundation. Consequently, all changes visible in the measurement results can actually be attributed to the component and are not induced by the ambient conditions.

The P 152 for mid-sized gears such as planet gears used in wind power combines dimension, form, and position measurements with gear measurement, making the operating principles used in high-volume and mass production applicable to large gears as well. Form measurements, such as roundness and cylindricity measurements on machine elements, are becoming increasingly important. Special measurements and evaluations on gears with a bearing function have therefore been developed, and are also available for the P 152.

The P 152 also offers all the possibilities of the "Done-in-One" principle in its diameter range. With its broad range of varied workpiece diameters and measuring tasks, it is also an ideal machine for contract gear manufacturers. It ensures high precision across the entire component spectrum from small to large gears, as well as for dimension and form measurements. Of course, software solutions for tool measurement are also available.
