Neuroblastoma is the most common abdominal solid tumour in childhood. Its removal implies a complex surgery that requires surgical experience due to the usual encassement of major abdominal blood vessels. Standard surgical ...

The aim of this paper is to review the recent evolution of additive manufacturing (AM) within the medical field of preoperative surgical planning. The discussion begins with an overview of the different techniques, pointing ...

Nowadays industry is immersed in a transition to the Circular Economy (CE) as a way to achieve resource efficiency in production processes. However, the implementation of CE closed loops is still in an initial phase and ...

Honing processes provide a crosshatch pattern that allows oil flow, for example in combustion engine cylinders. This paper provides an adaptive neural network model for predicting roughness as a function of process parameters. ...

In the present paper, roughness, force and vibration signals from ball-end milling processes are analysed. From the roughness signal actual feed value was obtained as expected. From the force and vibration signals both the ...

Additive manufacturing (AM) is an important, rapidly emerging, manufacturing technology that takes the information from a computer-aided design (CAD) and builds parts in a layer-by-layer style. Since about three decades ...

Cam-follower mechanisms are usually employed in different machines, like combustion engines, sewing machines, machine tools, etc. In the present paper, the option to manufacture cams utilizing wire electrical discharge ...

In the present work, design of a first approach of a test bench prototype for measuring friction in a piston-cylinder system is presented. The bench consists of a motor, belt and pulley transmission, crank mechanism, a ...

In a previous paper, artificial neural networks were employed for modelling average roughness Ra in rough honing processes as a function of process variables, namely grain size, density, linear speed, tangential speed ...
