O desgaste dos pun\u00e7\u00f5es \u00e9 frequentemente atribu\u00eddo \u00e0 qualidade do material, ao desempenho do revestimento ou ao tratamento t\u00e9rmico. Embora estes factores sejam importantes, nem sempre explicam o que realmente acontece na produ\u00e7\u00e3o.<\/p>\n\n\n\n

Em muitos casos, os padr\u00f5es de desgaste contam uma hist\u00f3ria mais precisa.<\/p>\n\n\n\n

N\u00e3o \u00e9 invulgar ver um pun\u00e7\u00e3o a polir suavemente enquanto outro come\u00e7a a lascar, apesar de ambos terem sido produzidos com as mesmas especifica\u00e7\u00f5es e estarem a funcionar na mesma ferramenta.<\/p>\n<\/div>\n\n\n\n

Normalmente indica que a carga n\u00e3o est\u00e1 a entrar em cada pun\u00e7\u00e3o da mesma forma.<\/p>\n\n\n\n

Quando o processo de corte come\u00e7a de forma ligeiramente diferente - mesmo que seja por uma pequena margem - a distribui\u00e7\u00e3o da tens\u00e3o altera-se. Uma aresta pode receber mais carga mais cedo, enquanto outra engata mais tarde. Ao longo de milhares de ciclos, esta diferen\u00e7a torna-se vis\u00edvel como um desgaste irregular.<\/p>\n\n\n\n

Pequenos desvios no perfil, na nitidez da aresta ou na precis\u00e3o do \u00e2ngulo podem alterar a forma como o pun\u00e7\u00e3o entra em contacto com o material. E quando o contacto muda, o percurso da carga tamb\u00e9m muda.<\/p>\n\n\n\n

Isto \u00e9 especialmente cr\u00edtico na produ\u00e7\u00e3o a alta velocidade, onde at\u00e9 as pequenas inconsist\u00eancias s\u00e3o amplificadas.<\/p>\n\n\n\n

Reflecte a forma como a for\u00e7a se move atrav\u00e9s da ferramenta.<\/p>\n\n\n\n

A compreens\u00e3o desta rela\u00e7\u00e3o facilita a identifica\u00e7\u00e3o das causas de raiz - e a melhoria da vida \u00fatil da ferramenta e da estabilidade do processo.<\/p>\n\n\n\n

It usually indicates that the load is not entering each punch in the same way. When the cutting process begins slightly differently \u2014 even by a small margin \u2014 the stress distribution changes. One edge may take more load earlier, while another engages later.
