The Influence of Circumferential Waviness of the Diamond Wheel Working Surface on the Machined Surface Roughness

Autor: V. I. Lavrinenko, O. O. Pasichnyi

Publikováno v: Journal of Superhard Materials. 41:278-280

The authors investigate the potential of damping down the undulating change of form of a diamond wheel working surface by dressing it with a single-point diamond tool. This is shown to alter the machined surface roughness parameters, namely: the heig

Grain shape as a factor governing the parameters of diamond electroplated coating of dressing tools. Part 2. Actual grain–graphite form contact area and related characteristics as input data for calculating the conditions of diamond electroplated coating application by electroforming method

Autor: O. O. Pasichnyi, M. N. Sheiko, V. N. Skok

Publikováno v: Journal of Superhard Materials. 38:47-50

The paper gives experimental data on the actual contact area between grains and the graphite form used in the process of deposition of a diamond coating onto a dressing tool by the electroforming method. Also, the authors provide the results of deter

Thermoelectric phenomena in machining processes and a study of their functioning in superabrasive grinding

Autor: A. A. Devitskii, V. I. Lavrinenko, O. O. Pasichnyi, S. A. Kukharenko

Publikováno v: Journal of Superhard Materials. 37:262-270

The paper addresses thermoelectric phenomena that occur in superabrasive grinding. It has been found out that the machining of hardmetals using diamond wheels is characterized by a negative value of tribo-thermal EMF, while in the case of cBN grindin

Publikováno v: Journal of Superhard Materials. 31:260-266

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
