À propos de ce projet

Notre modèle prototype est basé sur l'IoT, lui fournissant ainsi une architecture évolutive pour l'utiliser pratiquement n'importe où avec une connexion Internet. Il s'agit d'une CNC de 350 mm x 350 mm avec une zone de travail de 250 mm x 240 mm, fonctionnant sur un logiciel de contrôle de mouvement open source (GRBL). Même notre matériel est également principalement open source et entraîne donc la réduction des coûts majeure. Cette machine est entièrement fabriquée à partir d'articles achetés localement et peut usiner du bois, du plastique, du caoutchouc dur, de la résine dure, etc. Notre objectif principal est la fabrication de circuits imprimés à faible coût.

La perspective de l'envie de bois est également là.

Nous prévoyons également d'ajouter la prise en charge de l'usinage laser dans le cadre de notre futur projet.

Comme le système peut être actuellement contrôlé à partir d'un intranet local sans fil, nous voulons le faire évoluer pour créer une application Web modèle distribuée pour créer et connecter un écosystème de plusieurs de ces types d'appareils.

Les possibilités sont illimitées avec notre machine.

Notre modèle prototype a son cadre de base fabriqué à partir d'extrusions d'aluminium à fentes en T 2020 et de joints en L. La machine fournit une puissance d'environ 80 à 85 watts avec sa broche à commande CC de 2000 tr/min. Il a un schéma de mouvement de vis mère et de tige filetée avec des tiges lisses de guidage ayant des roulements à billes à encliquetage à rainure radiale pour des opérations en douceur le long des 3 axes.

Le pas de pas minimum est de 0,8 mm/tour avec 2000 pas/tour, nous avons une résolution de 1600 pour tous les axes. La taille de notre machine brute est d'environ 430x430x330mm et la zone de travail est d'environ 270x170x65mm avec une précision de position de 0,04mm. Notre portique à axe Z est imprimé en 3D à partir de zéro avec deux tiges de guidage.

L'axe Z se déplace de 4,8 cm avec l'embout de broche monté. Nous utilisons un outil de coupe V-bit à 45 ° à des fins de gravure de circuits imprimés, il prend également en charge les fraises en bout de 0,2 mm à 1,8 mm. Nous utilisons des moteurs pas à pas NEMA 23 avec un courant max de 3A pour chaque entraînement principal d'axe. Les moteurs sont entraînés par des pilotes 2.5A A4988 avec une résolution de micro-pas maximale de 1/16e nous offrant la précision d'usinage ultime à un coût très économique.

Pour la partie IoT, nous avons rendu possible le contrôle du routeur CNC à partir d'un écran sans tête comme un écran mobile/tablette (agissant ici comme notre IHM) depuis n'importe où avec une connexion Internet. Nous utilisons un Raspberry Pi et un routeur (de sécurité) connecté à Internet et exécutant un serveur Web pour fournir une interface permettant de contrôler notre CNC sans fil. Nous prévoyons également d'obtenir des informations précieuses sur les pièces de machines telles que le couple moteur en temps réel, le courant consommé, les vibrations, le bruit, etc. et d'obtenir des informations en temps réel sur une plate-forme Web pour une meilleure collaboration. Ce qui est peut-être appelé dans le secteur manufacturier IdO industriel (INDUSTRIE 4.0) .
