..., FE numerical simulation results are compared with published experimental results. The study shows that the lead hole diameter has an important influence on the screwing torque. 14 02 2007 21 10 2008 15 07 2009 automobile industry fasteners finite element analysis threading...

.... The assembly tools are modeled as five articulated parts to fully describe the tool characteristics. Tool feasibility analysis is executed to verify assembly tools’ feasibility applied on a fastener. In particular, both tool motion and tool placement constraints during tool applications are integrated...

...Kaspar Althoefer; Bruno Lara; Lakmal D. Seneviratne Screw fastenings account for a quarter of all assembly operations and automation of the process is highly desirable. This paper presents a novel strategy for monitoring this manufacturing process, focusing on the insertion of self-tapping screws...
