The optimization of the position and the magnitude of the clamping forces in machining fixtures
This paper presents a method which allows the optimization of the position and magnitude of the clamping forces for a specific case of processing: milling of a canal in a prismatic workpiece, using a multi- objective method, implemented with ANSYS software. The design variables are location dimensions of clamping elements, whose range of variation ...

Modelling pressure rolling of asymmetric rolling process
The paper presents a comparative analysis between experimental results and modelling in order to interpret the value of the contact pressure on the asymmetric longitudinal rolling. It is also intended action and the different behaviour of upper cylinder compared to the lower cylinder action in situations when both are driven, or only one operates. ...
