Abstract
In the physics of diamondabrasive machining— especially finishing operations—it is important to study the interaction of an individual grain with the machined material within the contact zone (1). Accordingly, we have developed experimental appa� ratus for simulating the microcutting of materials by microindentation (Figs. 1 and 2). Besides recording the indentation diagram and measuring the geometric dimensions of the impression or scratch, this system automatically records any combination of four parame� ters: the normal and tangential components of the indentation force; the length and depth of the scratch or impression. Elementary machining processes (microcutting, microslipping, microfurrowing, micro� indentation, etc.) using an indenter of any shape (sphere, pyramid, cone, flat stamp) may also be simu� lated at low deformation speeds, with recording of the given parameters.
