This application is drawn toward a combined coring and sawing machine for composite materials. The preferred embodiment combines the functionality of two machines typically usd in the prior art and minimizes both the cost and errors associated with larger cutting tools, e.g. diamond cutting devices, used in the prior art. Combining variable speed motor operation with pressure actuated advancement of cutting tools and automatic workholding actuation provides a system which is effectively open-loop "load" controlled as opposed to the open-loop "displacement" control systems most often used in the prior art. Simple and economical specimen ejection techniques are a further improvement over the prior art which often includes no ejection facility at all.
La présente invention concerne une machine à noyauter et à scier pour des matériaux composites. Le mode de réalisation préféré associe la fonctionnalité de deux machines généralement utilisées dans l'art antérieur. L'association du fonctionnement d'un moteur à vitesse variable (20) avec l'avance commandée par pression d'outils de coupe et l'activation de support d'outil automatique constitue un système qui est effectivement un système à commande de <=charge >= à boucle ouverte . Des techniques d'éjection d'éprouvettes (62) simples et économiques constituent une autre amélioration par rapport à l'art antérieur.
