To address such a complex problem, it is necessary to analyze the mechanics of the grinding process using probability statistics, which is the subject of this investigation. Such an analysis is applicable to both form and finish grinding (FFG), such as surface grinding and stock removal grinding (SRG), such as cut-off operation.

Abstract. This paper is the second of three parts which describe the analysis and simulation of the grinding process. Generation of the workpiece surface depends on the interactions between the grains of the wheel and the workpiece. The grinding wheel surface generated by dressing was simulated by the method described in Part I.

Double disc. 1. Modelling. Double-disc (DD) grinding is a high-productivity, high-accuracy process used widely in the automotive, bearing, tooling and semiconductor industries for creating parallel surfaces on two opposing flat faces [1]. Although over 100 years old, very little fundamental analysis existed on DD grinding until the 1990s.
