The paper considers the results of an experimental study of the external circular plunge-cut grinding process and the accompanying sound phenomena. Acoustic vibrations generated by the abrasive process are an indirect parameter that characterizes the state of the cutting process. This information is useful for controlling the grinding process and planning the technological process. The advantage of the method of accounting and forecasting the current state of the technological system during grinding, based on the use of acoustic data, is the possibility of its application without interrupting the production process.
The subject of experimental research is the acoustic signal that occurs during grinding. The purpose of the work is to conduct an experimental study of the dependence of the sound parameters of the grinding process on the technological conditions of the operation and their relationship with the parameters of the processing quality.
The main methods used to achieve a designated goal are experiment, measurement and analysis.
The experiment made it possible to obtain the data necessary for further processing. Registration of the sound signal generated during grinding at different feed rates is the main task of the experimental experiments. With the help of contact measurements, the real profile of the ground samples was determined, which is the most important stage for determining the relationship between the characteristics of the grinding process and the quality indicators of the processed surface. The analytical method was used to process the obtained experimental and measurement data. With its help, from a wide range, informative sound frequencies were identified, reflecting changes in the grinding process over time. The analysis of the measurement data made it possibleto evaluate the deviation of the polished samples from roundness, depending on the technological conditions of the operation, to determine the parameters that have the greatest influence on this criterion of the processing quality.
As a result of the study, a relationship was established between the acoustic characteristic - sound pressure and the quality parameter of the polished surface – deviation from roundness.
The knowledge gained about the sound characteristic of the grinding process can be applied for a more rational use of the resource of an abrasive tool through predicting the life of the grinding wheel.
