Підвищення ефективності шліфування плоских поверхонь шляхом регулювання температури різання

The grinding process is one of the main types of metal finishing in most factories not only in Ukraine, but also in the world. However, during grinding operations in the processing area, temperatures increase significantly, which cause a number of defects in the finished product. Such defects significantly affect the accuracy, durability of finished products, operational characteristics, etc. To improve the quality of the product, the temperature in the processing area should be reduced. In order to understand how to influence the temperature in the grinding zone and at the same time leave high-performance processing, it is necessary to identify the dependence that will help to identify those parameters that have an impact on the temperature. The main method of this publication is to conduct the theoretical analysis of the distribution of heat between the chip and the surface of the part being ground (in case of flat grinding) and, on this basis, to determine methods of reducing the temperature in the processing zone. Such theoretical information should be able to be used in practice. Most of the scientific works that today consider the grinding process, including the grinding of flat surfaces, are based on simplified relationships that do not take into account the depth of heat penetration into the surface layer of the workpiece and do not take into account the distribution of heat between the chip and the workpiece. The paper presents dependencies based on the heat conduction equation, which do not take into account heat distribution and take it into account. With the help of dependencies without taking into account heat distribution, it is known that the temperature is affected by both the grinding depth and the speed of the part. Dependencies taking into account heat separation into chips and workpiece are closer to the real grinding process, and these dependences made it possible to conclude that the main condition for reducing the grinding temperature is the reduction of conditional cutting stress due to the use of more advanced machining methods. The information presented in the article is of an overview nature.
