Ce travail de bachelor s\u2019inscrit dans le cadre du d\u00e9veloppement d\u2019une machine-outil combinant l\u2019usinage laser et des op\u00e9rations m\u00e9caniques de pr\u00e9cision telles que le per\u00e7age ou le fraisage. Cette machine vise \u00e0 offrir une solution compacte, performante et polyvalente, capable de r\u00e9pondre aux exigences \u00e9lev\u00e9es de l\u2019industrie horlog\u00e8re et microtechnique suisse.<\/p>\n\n\n\n

La m\u00e9thodologie suivie repose sur une d\u00e9marche de conception it\u00e9rative int\u00e9grant une analyse fonctionnelle compl\u00e8te, une estimation des efforts d\u2019usinage, une \u00e9tude dynamique du comportement vibratoire et une conception d\u00e9taill\u00e9e des cha\u00eenes cin\u00e9matiques et des b\u00e2tis. Les crit\u00e8res de rigidit\u00e9 statique et dynamique ont \u00e9t\u00e9 syst\u00e9matiquement int\u00e9gr\u00e9s aux d\u00e9cisions de conception, tout comme les contraintes d\u2019encombrement, de pr\u00e9cision et de perspectives d\u2019\u00e9volutions futures.<\/p>\n\n\n\n

Des simulations ont permis de quantifier les d\u00e9placements maximaux sous charge (jusqu\u2019\u00e0 5.6 \u03bcm au niveau du point d\u2019usinage pour les efforts de fraisage consid\u00e9r\u00e9s) et de d\u00e9terminer les fr\u00e9quences propres de la structure (premier mode de la structure globale \u00e0 223 Hz). Cependant, l\u2019analyse statique a mis en \u00e9vidence la sensibilit\u00e9 de l\u2019axe X aux d\u00e9formations torsionnelles.<\/p>\n\n\n\n

Ce projet constitue une premi\u00e8re \u00e9tape structur\u00e9e vers la r\u00e9alisation d\u2019un prototype fonctionnel. Il jette les bases d\u2019un d\u00e9veloppement industriel coh\u00e9rent pour une machine \u00e0 haute valeur ajout\u00e9e, tout en proposant des pistes concr\u00e8tes d\u2019am\u00e9lioration.<\/p>\n\n\n\n
