Abstract: This paper is a report on an improved technique to study the formation of chips while observing them through a metallurgical microscope. By using polished and etched specimens it is possible ...

Abstract: Mathematical model type machinability data base systems require suitable model building procedures to estimate the model parameters. The estimation procedure should be capable of using subjective ...

Abstract: The effect of five design and three operating variables on three different drill temperature responses is investigated. A total of 512 observations was made using a replicated two-level factorial ...

Abstract: Powder Metallurgy (P/M) materials, especially those made of high strength steels, are often reported in the technical literature to have poor machinability when compared to their wrought or cast ...

Abstract: An analytical temperature distribution along the cutting edge and on the flank face of a drill is obtained using Tsueda’s and Loewen and Shaw’s equations after modifications. Experimental ...

Abstract: Based on stochastic process modeling, a scheme has been developed for the detection and control of machining chatter. The range of the tool vibration signal is computed by a hybrid computer ...

Abstract: A practical way to achieve machine tool drive system accuracy is through compensation in the position control loop. Various strategies have been developed in which the compensation data are ...

Abstract: In Part II, a computer program that aids in the design of a twist drill is described, based on the analysis presented in Part I. A true drill and a “computer-designed” drill having identical ...
