- W3089074544 abstract "Questions of stabilization of a thermal mode in a cutting zone at a round grinding with application of a lubricating-cooling liquid (SOJ) are considered. It is shown that the effective action of coolant allows to reduce the heat stress of the process by accelerating heat transfer in the system of applying coolant. The actual problem of heat release in technological systems of machining is solved - the construction of a mathematical model of the system of coolant application with the determination of the coolant temperature at any stage of the grinding technological cycle and the degree of its influence on the thermal deformations of the machine. To solve this problem, an improved scheme is proposed and a mathematical model of the temperature regime is constructed for the coolant supply system, which makes it possible to determine the current temperature of the coolant at control points associated with individual elements of the coolant supply system; allows to calculate the current coolant temperature during system operation in non-stationary and stationary modes. The mathematical model is implemented in the form of an algorithm and a separate module in the author's program Heat calculation parameters of the thermal regime of coolant. The program allows performing a multivariate calculation of the coolant temperature at all control points of the system when operating in non-stationary and stationary modes. Calculated analytical studies have shown the correspondence of the constructed mathematical model to real thermal processes in the system of coolant application. Scientific novelty of the work is that for the first time a functional relationship between the temperature in the cutting zone during grinding and the temperature of the coolant in the reservoir of the coolant system has been established. The developed mathematical and software tools are recommended for application at development of specifications of the necessary volume of coolant for grinding machines." @default.
