The spherical cutting edge on the ball end mill directly affects its cutting performance. This paper presents a practical method for end mill rakeclearance face modelling. The rake face is a developed ruled surface to fulfill the desired normal rake angle. Revolution surface of the bottom curve on the rake face avoids the interference between the wheel with the designed rake face while grinding.

Neural simulation of ball mill grinding process Zakamaldin A. A.; Shilin A. A. Abstract. This study is aimed at getting simplified model of mill filling technological process of fine crushing in a closed-circuit grinding with screen separation. Optimal and simple model structure are supposed to be used in adaptive predictive control loop.
Jan 01 2006 The models are characterized by the process parameters such as grinding force grinding temperature etc. as well as work results including surface topography and surface integrity. Furthermore the capabilities and the limitations of the presented model types and simulation approaches will be exemplified. Previous article.
Jan 17 2014 Abstract This paper introduces the development and implementation of a ball mill grinding circuit simulator NEUSimMill. Compared to the existing simulators in this field which focus on process flowsheeting NEUSimMill is designed to be used for the test and verification of grinding process control system including advanced control system such as integrated control.
The grinding mechanism is the base of developing new precision machining technology especially for brittle materials including ceramics. In previous work many results were gained from single grit cutting model in which a grit is in contact continuously with a workpiece similar to the indentation or scratching process to model the material remove in grinding processing.
