Diseño y simulación de una sierra circular de banco y fabricación de componentes seleccionados en torno de control numérico computarizado (CNC) modelo C420

Abstract

The objective of this paper is the design and simulation of a bank cutting circular saw, to subsequently manufacture selected components in CNC lathe ROMI C420, with this information verify the tolerances obtained and the tolerances that this design requires. The concurrent design method was applied and the analysis of the existing product was carried out by the competition, from which information was obtained that allowed matching the requirements that the design must achieves for the user and the engineer. The design of the elements was made with the criterion of the theory of failure of the maximum distortion energy, applicable to isotropic materials and allows a satisfactory design for this application. For the simulation theme, commercial finite element analysis programs were applied, which allowed to validate the data obtained in the calculation memory. The programming of the G code, for each element susceptible to manufacture the CNC lathe, was made in order to optimize the machining operations on the base material of each material, the results that were obtained when checking the tolerances of the manufactured parts were as expected, which allowed the coupling of catalog pieces and functional manufactured elements. Mainly this project has as a result an assembly for didactic use, that contributes a knowledge how to do it and that materializes the possibilities of manufacture in CNC lathe.
