The results of theoretical studies on the dynamic characteristics of the process of vibroprocessing are presented, the essence of which is to create conservative zones limited by the current lines of a certain fixed vector field, which contributes to the formation of a macrodomain structure in the working medium. Domain structuring of the working tool reflects the configuration of the field grid of the external dynamic field and is the basis of the technology of vibration processing.

“…• Machining stability is the best and the worst when the phase difference between adjacent continuous waviness generated by grit-workpiece interaction takes values of π/2 and 3π/2 respectively. [5] and [6], many studies on the optimization of the surface topography characteristics of abrasive wheels [7] and machining conditions have been conducted based on minimal energy consumption or a material removal mechanism under different grinding phases [8] to [10]. The relevant experiments are also performed to validate these research findings.…”

The instantaneous energy consumption in the grit-material interaction zone is an important indicator to represent the efficiency of grinding. In contrast to methods based on chip crack and formation or energy consumption from experimental measurement, this paper presents an improved differential model of energy consumption that takes account of dynamic grinding force, forced-vibration induced by the eccentrically grinding wheel rotation, and the phase difference between adjacent regenerative surface waviness. Furthermore, the vibratory amplitude and relevant frequency elements of a wheel-workpiece coupled system are analysed to optimize the key machining conditions involved in spindle speed, pack density of abrasive wheel and effective cutting space of adjacent contour grits in discrete transverse plane. It demonstrates that machining stability is the best when the phase difference value is π/2 between continuously formed adjacent waviness generated by grit-workpiece interaction, i.e. the calculated value of instantaneous grinding energy consumption reaches its maximum value. In comparison to stable situations, an unstable grinding process is excited when the phase difference value is 3π/2, i.e. micro-grinding force and vibration reinforce each other. It proves that a satisfied and stable grinding process can be controlled in real-time or in-situ by means of utilizing combination of optimal parameters, such as spindle speed, effective pack density, and the cutting space of abrasive grits. The presented mechanism is practical and can provide good guidance for further studies on machine-tool dynamics, time-domain or frequency-domain analysis of grinding vibration, and then on depth distribution of cut and ground surface accuracy.

This paper presents a study on the optimum calculation of exchanged grinding wheel diameter when external grinding alloy tool steel 9CrSi. In this study, the effects of the grinding process parameters including the initial grinding wheel diameter, the total dressing depth, the radial grinding wheel wear per dress, and  the wheel life on the exchanged grinding wheel diameter were considered. Furthermore, the impact of cost elements including the machine tool hourly rate and the grinding wheel cost were investigated. To evaluate the effect of these factors on the optimum exchanged grinding wheel diameter, an "experiment" was designed, and a computer program was built for performing the "experiment". Based on the results of the "experiment", a formula for determining the optimum exchanged grinding wheel diameter was proposed.
