The geometrical constraints and dimensional tolerances lead to specific design issues of MEMS manipulators for biological applications. target properties become even more important in the case vitro manipulation cells. Several solutions have been proposed literature, however, some related thermal heating microgripper tips electric voltage effects still remain unsolved. This paper reports additi...

Abstract Automated tape layup (ATL) has been used extensively for manufacturing composites laminates using unidirectional prepregs high‐performance industries like aerospace. Residual stress is one of the defects that adversely affect quality. These stresses geometrical tolerances in form distortion final product and are found to have a detrimental impact on mechanical properties. In‐line monit...

Geometrical product specification and verification (GPS) standard system defined by ISO/TC 213 is a universal language for expressing tolerances and communicating functional requirements for geometrical workpieces in technical drawings. GPS is developed through cooperation by more than 60 countries and documented in hundreds of paper files. Hence, the GPS world is very complex and difficult to ...

The tolerancing process links the virtual and the real worlds. From the former, tolerances define a variational geometrical language (geometric parameters). From the latter, there are values limiting those parameters. The beginning of a tolerancing process is in this duality. As high precisions assemblies cannot be analyzed with the assumption that form errors are negligible, we propose to appl...
