• #### A Parametric Design of Ball End Mill and Simulating Process

On the basis of creating a mathematical model of a ball end mill cutting edge curve, we generate the 3D model of the cutter in CATIA. Moreover, the conditions of the engagement between the grinding wheel and rake surface to avoid interference are proposed. As a result, the grinding wheel center location and orientation axis are defined. 2. A modeling program for ball end mills is developed in

In the present study the modeling of the HEBM process is presented. The impact velocity, impact angle, rotation speed, mass of balls, ball-to-powder weight ratio and time of milling have been taken into account in order to calculate the energy transferred from the balls to the powder. Two different systems, namely, TiN-AlN and polysalicylic acid were experimentally investigated in order to

Mathematical models, which link the external signals of ball mill with its internal parameters, were established to predict the internal parameters of ball mill. Experimental results showed that the mathematical models could directly predict the internal parameters of ball mill once the external signals were obtained. The tri-sensor measurement

CYCL and MILL models were selected to simulate SAG mill, Hydrocyclone packages and ball mill units. SAGT and MILL models both are based on the population balance model of grinding process. CYCL model is based on Plitt's empirical model of classification process in hydrocyclone units. It was shown that P 80 can be reduced to about 40 Pm and 42 Pm for the first and second proposed circuits
