The paper addresses the simplest 3D model—a barrel made of parabolic and circular staves—for a diamond grain in the electroplated coating of dressing tools. It is shown that the proposed concepts of a diamond grain shape provide, on the one hand,

A test procedure for complex-form rollers is put forward; it involves the so-called quasi-infeed dressing scheme that simulates the real infeed dressing. The procedure requires no specialized expensive equipment but can be implemented on universal eq
