Geometric Tolerances: Impact on Product Design, Quality Inspection and Statistical Process Monitoring

Bianca M. Colosimo is an associate professor in the Department of Mechanical Engineering at the Politecnico di Milano, Milan, Italy, where she received both her M.S. degree in Industrial Engineering and her PhD degree in Manufacturing and Production Systems. Since 2001, she has collaborated with the Engineering Statistics Laboratory of the Industrial Engineering Department of the Pennsylvania State University. She is a member of the editorial board of the Journal of Quality Technology. She is the author of about 60 papers in international and national journals and conference proceedings, including over 20 refereed papers (in the Journal of Quality Technology, Technometrics, Communications in Statistics and Journal of Applied Statistics, among others). She is a senior member of the American Society for Quality (www.asq.org), a member of Informs (http://www.informs.org/) and of the AITEM (Italian association of manufacturing engineers (www.aitem.org)).

Her research interests are mainly in the area of quality monitoring and process adjustment, with special attention to discrete part manufacturing. Further research activity is devoted to manufacturing process optimization. Her main research target is to take full advantage of new methods and tools developed in the area of applied or industrial statistics for solving industrial manufacturing problems.

Nicola Senin is an associate professor in the Department of Industrial Engineering at the University of Perugia, Perugia, Italy, where he received his M.S degree in Mechanical Engineering. Since 1995 he has collaborated with the Computer-aided Design Laboratory at the Massachusetts Institute of Technology (MIT), in Cambridge (MA), USA. He is the author of about 30 publications in international and national journals and conference proceedings, including about 10 refereed papers in international journals (in the ASME Journal of Mechanical Design, the Computer Aided Design Journal, the Journal of Robotics and Computer-integrated Manufacturing, and Wear, among others). He is a member of the AITEM (Italian association of manufacturing engineers (www.aitem.org)).

His research interests are mainly in the area of inspection of manufactured surfaces, with particular reference to three-dimensional surface topography analysis at the micro and sub-micro scales. Additional research activities are related to the development of computer-based frameworks for supporting collaborative product design and manufacturing.
