Bill Tandler

Bill's professional experience includes three years at the Hewlett Packard R&D laboratory in Palo Alto, CA, where he helped develop a quadruple mass spectrometer, five years with the laser manufacturer Coherent, Inc. as International Marketing Manager, followed in 1975, by the founding of Multi Metrics, Inc. As President, Bill's activities at Multi Metrics included marketing metrology equipment for Carl Zeiss and other companies, pioneering the contract inspection business, and managing the design and development of several dimensional metrology software systems. These included "Inspector S", the world's first programmable, SPC based software system for automating mechanical inspection with digital electronic calipers, micrometers, height gages and indicators, and "GEOMET", a 3D geometry processing software system for coordinate measuring machine retrofit. Since 1992, Bill has focused on GD&T research and development, training and consulting. Bill is currently a member of the ASME Y14.5.1 Mathematization Committee; a subject matter expert for Working Group 4 of the ASME Y14.5 Standard focused on Datums, and has been a contributor to ISO TC213 in the realm of Datum Reference Frame construction. Bill is the author of "The Little Encyclopedia™ of GD&T" , "The SmartGD&T™ Pocket Guide", and many GD&T course manuals, as well as e-GAD™ Software (electronic GD&T Aided Design) delivering on-demand e-learning/support enabling "encoding" and "decoding" GD&T, to eliminate dependence on "interpretation". Bill is a frequent speaker at international meetings on computer aided tolerancing and coordinate metrology.

Bill has a substantial, hands-on background in manufacturing and inspection technology, and is responsible for creating SmartD&T™ Technology , the unique, rule based system, permitting GD&T to be encoded and decoded, rather than interpreted.

Bill received a Masters degree in Applied Physics and Numerical Mathematics from the Swiss Federal Institute of Technology (ETH) in Zürich, Switzerland.
