Abstract
Introduction. The development of a method for controlling the accuracy parameters of large axisymmetric bodies is an urgent task that is being solved by specialists from various industries. Application for adjustment and correction of machining based on the measurement of surface shape parameters directly during machining is shown. Purpose of work is to improve mobile processing technologies using special measuring devices and processing module. For this, the problems of development and analysis of mathematical models that describe the process of basing and machining of a riding ring as a cylindrical object with a non-stationary axis of rotation is solved. A study of the methodology is carried out, control schemes are designed, and equipment for processing mobile devices is developed. The methods of research are the analysis of the developed mathematical models, taking into account the assignment of effective technological modes. Three-dimensional and simulation modeling of processing, hardware-software implementation of proposed solutions, and statistical processing of measurement results are carried out. Results and discussion. The algorithm and methodology are tested with a three-dimensional simulation model. The presented methodology for measuring and calculating the allowance for mechanical restoration can significantly reduce machining time compared to active form control and compared to the traditional method of assigning an allowance for machining. The measurement and adjustment of the allowance based on the measurement data is not carried out after each measurement, but only in the case of transition to finishing transitions or for accuracy control. It is determined that by providing a single technological base for each individual technological transition within the framework of the mobile technology of machining of the rolling surface of the riding rings of technological drums, the accuracy and speed of processing increase. An original design of the device for monitoring parameters is developed; an experimental assembly and a laboratory model of the riding ring are made.
