摘要:
A transfer device for a very high speed adiabatic face milling machine whose configuration and operation provide a highly efficient machining process suitable for production manufacturing conditions. The milling machine preferably operates at speeds of approximately 15,000 sfm and at efficiencies of approximately 7 cubic inches per minute per horsepower. The preferred milling operation is conducted without the use of cooling liquids, instead employing a chip removal system which enables the milling machine to operate truly adiabatically such that no heat is transferred to the workpiece or the cutter. The efficiency of the chip removal system is such that chip recutting is nearly eliminated and tool life is improved. The transfer device, by use of a transfer arm and associated grasping arms, locates the workpiece within a corresponding nesting slot defined by the grasping arms in order to accurately and securely move the workpiece between workpiece support structures so as to position opposing sides of the workpiece in the fixture for subsequent machining.

Fraiseuse de surface adiabatique (10) et à grande vitesse, dont la configuration et le fonctionnement permettent d'obtenir un processus d'usinage de grande efficacité dans des conditions de fabrication de pièces. La fraiseuse fonctionne de préférence à des vitesses périphériques en pieds par minute de 15 000 environ, et à des rendements de 7 pouces cube par minute par cheval de puissance. L'opération de fraisage préférée est effectuée sans utiliser de liquides de refroidissement, et utilise à la place un système d'enlèvement de copeaux qui permet à la fraiseuse de fonctionner de manière véritablement adiabatique, de sorte qu'il n'y a aucun transfert de chaleur vers la pièce (20) ou l'outil de coupe (22a, 22b). L'efficacité du système d'enlèvement de copeaux est telle qu'il n'est pratiquement plus nécessaire de retailler les copeaux, et la durée utile de l'outil en est ainsi prolongée. La fraiseuse comprend également une structure d'outil de coupe, un dispositif de serrage et des dispositifs de transfert (24) améliorés.
摘要:
The invention relates to a tool (102, 202, 302, 402, 502) for machining materials in a rotating manner, comprising at least one elongate cutting chamber (112, 212, 312, 412, 512) which is arranged on the peripheral side (106, 206, 306, 406, 506) of the tool (102, 203, 302, 402, 502). A plurality of cutting elements (118a-h, 218a-h, 318a-e, 418a-e) are arranged in the cutting chamber (112, 212, 312, 412, 512) or adjacent thereto. The tool (102, 202, 302, 402, 502) inscribes upon an enveloping surface (102, 220, 320, 420, 422) when rotated. The cross-section (130, 132; 230, 232; 330, 332; 430, 432),which is defined by the surface of the cutting chamber (112, 212, 312, 412, 512) and the enveloping surface (120, 220, 320, 420, 422), has different dimensions along the path of the cutting chamber (112, 212, 312, 412, 512) in relation to the height of different cutting elements (118a-h, 218a-h, 318a-e, 418a-e).
