We consider the large N spectrum of the quantum mechanical hamiltonian of two hermitean matrices coupled via a Yang-Mills interaction. In a framework where one of the matrices is treated exactly and the other is treated as a creation operator impurit

High-speed steel drill life is found to be a strong function of the work material hardness (Tl α HB−16) when drilling cast iron. This strong dependence may account for the large variation in the life of the drills, which is observed in industrial

Specimens of beef bone were analyzed for thermal conductivity and thermal capacity. The thermal conductivity was about 7 X 10(-4) cal/cm/sec/degrees C, that is about the same as for other tissues. As regards thermal capacity, the determination of 0.7

The effects of additions of lead and sulphur to steel upon tool-face friction F, cutting energy per unit volume u, and tool-face temperature θ¯t were investigated. By means of high-speed flash pictures of chips in the process of being formed, it wa

The oblique tool, which has a cutting edge that is inclined to the direction of motion of the workpiece at an angle other than 90 deg, represents the most general type of cutting tool. The more complex three-dimensional tools of production may be rel

The action of lead in free-machining steel is discussed and the thickness of the layer of lead responsible for the improved lubrication between chip and tool is found to be extremely thin. Measurements made on the same steel with and without lead pre

The nature and extent of grinding wheel wear in precision grinding were investigated directly from the wear particles removed from the wheel. A statistical analysis of the wear particle size distributions was developed to determine the relative amoun
