Cenit Fagor

With machine tools, the use of machines with optimised drives improves both product quality and machining time. The drives must be designed in optimum fashion and their control adjusted correctly.

In this context, the problem encountered by users when adjusting a CNC (Computer Numerical Control) is the fact that they do not know the optimum settings. In addition, in order to adjust the CNC as well as possible, the dynamic characteristics of the drive need to be known.

TEKNIKER, In order to make the adjustment process easier, the TEKNIKER foundation has collaborated on the CENIT project to develop a new utility incorporating the Fagor family of controls. Controls that will carry adjust the CNC parameters automatically or semi-automatically according to the priorities and knowledge of the user. This auto-adjustment process is divided into two stages: the first consisting of the identification of the dynamic operating characteristics by in-machine measurements. The second stage consists of the optimum adjustment of the control link parameters.

Methodology for calculating cages using finite elements

We have developed a methodology for the numerical simulation of epicycloidal and planetary gear cages.

This is a highly complex non-linear calculation involving multiple contacts between different solids, suffering complex inertial forces due to the accelerations of each solid and those produced by the relative movement between the same.

Nowadays, a dynamic simulation such as this, using explicit calculations, would involve unacceptable computing costs, leading us to develop a methodology to simplify it to an implicit static non-linear calculation.
