Baykov A. Providing a surface quality of products from a natural stone at finish grinding due to perfection of the tool and the schemes of processing

The object of the thesis's researches is the technological operations of natural stone thin, flat surfaces diamond grinding. The aim of this work is to improve the efficiency of the natural stone's fine grinding process. That provides the necessary flat surfaces roughness' parameters by means of grinding tool's elastic characteristics validation. Also it provides the geometric accuracy by means diamond tools layer rational construction development and mover on surface. The following methods have been used in the thesis: the basics of mechanical engineering technology, metal-cutting theory, mathematical analysis and statistical methods. Obtained results have the following scientific and practical value: 1. The instrument's working layer construction and flat surfaces cut-map of the removal irregularity over the surface are discovered. 2. Thermal influence method for grinding tool's elastic adhesive during grinding process is offered. 3. Frontal grinding tool's working layer construction is developed and flat surface's cut-map is offered. Things above increase the removal uniformity of the material by 15-20%. 4. Developed a for determining the machinability of rocks and stone: patent № 63487A S04V4/00. 5. Implementation: Enterprise "Mosaic" (Ukraine), Snezhnoye Engineering Works JSC "Motor Sich" (Ukraine), SHEI "Donetsk National Technical University" (Ukraine). Industry - engineering, natural stone company of Ukraine.
