Abstract: This work deals with the efficiency of energy transfer in impact forming machines due to the interaction of the process with machine structure as represented by a two degree-of-freedom (dof) ...

Abstract: Dynamic acceptance tests based upon forced vibration tests employing electromagnetic exciters are applied to a center-type lathe. The stability is assessed in terms of the coefficient of merit ...

Abstract: The dynamic response of the shear plane and the variations of the dynamic cutting coefficients are experimentally investigated at various values of feed, cutting speed, rake angle, clearance ...

Abstract: The dynamic behavior of three different designs of a cantilever boring bar are compared by means of forced vibration tests. These are a bar with diametrically opposed flats machined along its ...

Abstract: Machine tool chatter is essentially a statistical phenomenon. The dynamic characteristics of machine tools as well as the dynamic coefficients of the cutting process are statistical quantities ...

Abstract: A mathematical model is proposed for the prediction of the grinding process chatter. It considers the machine structure as a multidegree of freedom system and takes into account various parameters ...

Abstract: A theoretical model has been developed for representing the grinding forces. This is based on the fact that the chip formation during grinding consists of three states: ploughing, cutting, and ...

Abstract: The noise generated from an impact forming machine arises mainly from structural vibrations and consequently accurate determination of the modal characteristics of the machine is necessary in ...

Abstract: The dynamic behavior and the cutting performance of a horizontal milling machine, the structure of which was fabricated by bonding, are compared with those of a machine of nominally identical ...
