Sheffield Measurement Launches Cordax® Discovery® III Product Line

Fond du Lac, WI – April 1, 2008 – Sheffield Measurement, a brand of Hexagon Metrology, Inc., today unveiled the new Cordax Discovery III, the next evolution of their original shop floor CMM product line. The Discovery III offers higher accuracy, improved thermal performance, and a new industrial design. Mechanical design improvements and advanced geometric thermal compensation algorithms form the basis of the Discovery III performance enhancements. Available in three measuring ranges from 20x24x16 to 30x40x24, the new CMM is sized to suit the majority of manufactured parts. The D28 CMM is now available for shipping. The D8 and D12 CMMs will be available later this year. Sheffields original Cordax Discovery CMM created the concept of affordable automatic dimensional inspection at the point of manufacture on the shop floor.
The main design features of Discovery III are hardened linear guides and recirculating ball bearings in place of air bearings. This improvement forms the backbone of Discoverys shop hardened design. When combined with the new lighter weight bellows covers, Discovery III is especially resistant to shop-borne contaminants that resign traditional air bearing CMMs to the quality laboratory. In addition, with no requirement for air and a roll-around stand, Discovery III advances shop floor layout flexibility to a whole new level.

Discovery III continues to pioneer innovations like its predecessor – the Discovery CMM – more than a decade ago. Namely, the relocation of the CMM from the quality lab to location in the factory wher precise dimensional inspection is required, stated Product Manager, Eric Bennett. Whether thats receiving inspection, R&D, or shoulder-to-shoulder with machine tools in some of the harshest manufacturing environments imaginable, Discovery CMMs are up to the task. The performance improvements designed into Discovery III further enhance the already strong value proposition for the customer.

Improved Accuracy and Thermal Performance

Discovery III also provides improved accuracy and thermal performance by a combination of mechanical and controller improvements. First, bimetallic interfaces – places in the structure wher dissimilar materials meet – have been further reduced from the mechanical design, making thermally induced geometry errors more predictable, and thus correctable using new advanced geometric thermal compensation algorithms in the controller.

New Probing Options

The new CMM also offers a wide range of probing options from economical touch trigger probes to high performance continuous contact analog scanning probes. New Swiss-made TESASTAR® probing systems are being introduced on Discovery III CMMs. The TESASTAR-m-m8, the new TESA® automatic indexing probe head, has all of the advanced design features of the TESASTAR-m, plus a direct M8 interface. The new TESASTAR-mp probe and TESASTAR-pr probe rack work together to provide easy automatic changing of magnetically coupled probe modules.
