Il est \u00e9galement proportionnel \u00e0 la rigidit\u00e9 et \u00e0 la stabilit\u00e9 du mat\u00e9riau. Par cons\u00e9quent, lors de la conception des pi\u00e8ces, nous devons r\u00e9duire l'influence de ces facteurs sur la d\u00e9formation. Ensuite, pour certaines pi\u00e8ces \u00e0 structure importante, nous devons concevoir une structure raisonnable afin de r\u00e9duire la d\u00e9formation.<\/p>\n<p><strong>\u00a02. Le serrage<\/strong><\/p>\n<p>Tout d'abord, nous devons choisir le bon point de serrage. Ensuite, nous devons s\u00e9lectionner la force de serrage appropri\u00e9e \u00e0 cette position et maintenir le point de serrage et le point d'appui en ligne, de sorte que la force de serrage agisse sur le point d'appui. Il est important que le point de serrage soit le plus proche possible de la surface usin\u00e9e et que la position choisie soit celle o\u00f9 la force ne risque pas de provoquer une d\u00e9formation.<\/p>\n<p>Nous devons \u00e9galement faire attention \u00e0 l'ordre de la force de serrage lorsqu'il y a plusieurs forces de serrage sur les pi\u00e8ces d'usinage. Il faut d'abord appliquer la force de serrage des pi\u00e8ces usin\u00e9es et du point d'appui, puis appliquer la force de serrage de l'effort de coupe.<\/p>\n<p>Il convient alors d'augmenter la zone de contact entre la pi\u00e8ce \u00e0 usiner et le dispositif de fixation et d'utiliser la force de serrage axiale pour am\u00e9liorer la rigidit\u00e9 de la pi\u00e8ce \u00e0 usiner.<\/p>\n<p><strong>\u00a03. le traitement<\/strong><\/p>\n<p>Au cours du processus de coupe, la pi\u00e8ce usin\u00e9e subit une d\u00e9formation \u00e9lastique sous l'effet de la force de coupe. D'une part, il peut r\u00e9duire la r\u00e9sistance entre l'outil et la pi\u00e8ce \u00e0 usiner, d'autre part, il peut am\u00e9liorer la capacit\u00e9 de dissipation de la chaleur de l'outil lors de la coupe des pi\u00e8ces \u00e0 usiner, r\u00e9duisant ainsi la contrainte interne r\u00e9siduelle des pi\u00e8ces \u00e0 usiner.<\/p>\n<p>La chaleur g\u00e9n\u00e9r\u00e9e par la friction entre l'outil de coupe et la pi\u00e8ce usin\u00e9e d\u00e9forme \u00e9galement cette derni\u00e8re. En g\u00e9n\u00e9ral, nous pouvons adopter une vitesse d'usinage \u00e9lev\u00e9e pour r\u00e9duire efficacement la d\u00e9formation.<\/p>\n<p>Afin de garantir la pr\u00e9cision des pi\u00e8ces usin\u00e9es, il convient d'utiliser une quantit\u00e9 raisonnable de coupe. Lors de l'usinage de pi\u00e8ces \u00e0 parois minces avec une grande pr\u00e9cision, nous adoptons g\u00e9n\u00e9ralement un usinage sym\u00e9trique. En effet, il permet d'\u00e9quilibrer les contraintes relatives des deux c\u00f4t\u00e9s, d'atteindre un \u00e9tat stable et de rendre l'usinage sym\u00e9trique.<a href=\"https:\/\/www.symachining.com\/fr\/machined-components\/\" target=\"_blank\" rel=\"noopener\"> pi\u00e8ces d'usinage<\/a> qu'apr\u00e8s l'usinage lisse.<\/p>\n<p><a href=\"https:\/\/www.symachining.com\/wp-content\/uploads\/2018\/07\/precision-machined-parts.jpg\" rel=\"attachment wp-att-1205\"><img decoding=\"async\" class=\"aligncenter wp-image-1205 size-full\" src=\"https:\/\/www.symachining.com\/wp-content\/uploads\/2018\/07\/precision-machined-parts.jpg\" alt=\"precision machined parts\" width=\"640\" height=\"480\" \/><\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Au cours du processus d'usinage, la d\u00e9formation des pi\u00e8ces usin\u00e9es est fr\u00e9quente et difficile \u00e0 r\u00e9soudre.
