Implementación del Proceso de Manufactura de un Microengranaje por Medio de Microfresado

Abstract

This degree work presents the successful implementation of the manufacturing process of a microgear through micromilling on a Swiss-type CNC lathe. Three specific objectives were established: - Sizing the microgear: The DIN 3960 standard was applied to determine the dimensions and characteristics of the gear, ensuring its correct functioning. - Plan the manufacturing process: The sequence of operations, selection of materials, tools and cutting parameters was defined, optimizing the process for the efficient production of the microgear. - Develop manufacturing: G codes were programmed and MATLAB software was used to control the micromilling process precisely, allowing the creation of the gear teeth with the required tolerances and geometries. Adjustments and testing were performed during the manufacturing process to ensure the quality and precision of the microgear. Finally, the successful assembly of the microgear into a functional assembly was achieved, evidencing the viability of the developed process. This degree work provides knowledge about the manufacturing of microgears on Swiss-type CNC lathes, including the selection of materials, tools, programming and control strategies. The results obtained establish a basis for future research in the area of microfabrication, with a view to the production of increasingly smaller and more precise components.
