Lorsque la hauteur des bavures devient irr\u00e9guli\u00e8re, la premi\u00e8re r\u00e9action est g\u00e9n\u00e9ralement d'ajuster le d\u00e9gagement.<\/p>\n\n\n\n

Et dans certains cas, cela fonctionne.<\/p>\n\n\n\n

Cependant, dans les processus de fabrication progressive, la variation des bavures est souvent le signe d'un probl\u00e8me plus profond.<\/p>\n<\/div>\n\n\n\n

Il est possible que le d\u00e9gagement reste inchang\u00e9 alors que les conditions de bavure fluctuent d'une station \u00e0 l'autre, voire au fil du temps au sein d'un m\u00eame parcours.<\/p>\n\n\n\n

En effet, la formation de bavures est directement li\u00e9e \u00e0 la mani\u00e8re dont le mat\u00e9riau est cisaill\u00e9.<\/p>\n\n\n\n

Si les poin\u00e7ons ne p\u00e9n\u00e8trent pas dans le mat\u00e9riau de mani\u00e8re coh\u00e9rente, le m\u00e9canisme de coupe lui-m\u00eame change. Le mat\u00e9riau peut se fracturer plus t\u00f4t dans un cas et plus tard dans l'autre, ce qui se traduit par des conditions d'ar\u00eate diff\u00e9rentes.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Ces diff\u00e9rences peuvent \u00eatre subtiles, mais elles sont suffisantes pour affecter la formation des bavures.<\/p>\n\n\n\n

Par cons\u00e9quent, ce qui semble \u00eatre un probl\u00e8me de d\u00e9gagement peut en fait \u00eatre un probl\u00e8me de coh\u00e9rence.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

L'essentiel n'est pas seulement d'avoir la bonne g\u00e9om\u00e9trie, mais de s'assurer qu'elle se comporte de la m\u00eame mani\u00e8re \u00e0 chaque cycle.<\/p>\n\n\n\n

Une qualit\u00e9 de bavure stable d\u00e9pend d'un comportement de coupe stable - et cela commence par la fa\u00e7on dont le poin\u00e7on s'engage dans le mat\u00e9riau.<\/p>\n\n\n\n

It is possible for clearance to remain unchanged while burr conditions fluctuate from station to station \u2014 or even over time within the same run.
