Parallel mechanisms have been studied during the last two decades, due to the fact that they present some potential advantages in a comparison with serial structures. This work presents the kinematic analysis of a novel 3-dof asymmetric parallel mechanism, purposely conceived for milling applications. In a comparison with the previous proposed concepts, this type of kinematic structure shows so...

Friction stir welding (FSW) is a joining process where the regulation of some technological parameters, like machining forces and tool velocities, is essential to ensure the required product quality. Therefore industrial robots are often equipped with force sensors in order to have a monitoring of the interaction forces between the rotating tool and the sheets metal. Alternatively a mathematica...

This work intends to deal with the optimal kinematic synthesis problem of Tricept parallel manipulator. Observing that cuboid workspaces are desirable for most machines, we use the concept of effective inscribed cuboid workspace, which reflects requirements on the workspace shape, volume and quality, simultaneously. The effectiveness of a workspace is characterized by the dexterity of the manip...

Many different Parallel kinematic machine architectures have been proposed, but few have actually been used in production environments. The class of machine structures referred to as hybrid parallel kinematic machines have been more successful than most and have been employed in a wide variety of applications. These machines are however still affected by many of the limitations associated with ...

In this research, Artificial Neural Networks (ANNs) have been used as a powerful tool to solve the inverse kinematic equations of a parallel robot. For this purpose, we have developed the kinematic equations of a Tricept parallel kinematic mechanism with two rotational and one translational degrees of freedom (DoF). Using the analytical method, the inverse kinematic equations are solved for spe...

This paper describes the concept of high speed cutting (HSC) milling machine based on hybrid kinematic structure. Hybrid machines are characterized by connecting advantages of both type mechanisms together – high dynamics of parallel mechanisms for positioning and high flexibility and high mobility range of serial mechanisms for orientation. For the application for HSC milling operation we sele...
