The purpose of this work is to analyze the influence of technological process parameters of camshaft cams finishing antifriction non-abrasive treatment (FANT) on the quality of antifriction coating and to obtain their rational values.
The paper presents the research results, aimed at improving the quality of obtaining antifriction coatings during the utilization of finishing antifriction non-abrasive treatment of camshaft cams in automotive and tractor engines. For the criteria of optimization, the conditions of antifriction coating quality (continuity, relative surface roughness) and operational indicator – wear intensity of the sample were chosen. Response functions were the regimes of FANT under a defined scheme of applying the antifriction coatings to the working surface of the camshaft cams. After performing a multifactor experiment, based on the results, a series of mathematical models in the form of regression equations were obtained. The analysis of mathematical models allowed optimal variable values of regime parameters of FANT to be determined.
The results of the provided research yielded optimal regimes of FANT, namely the tool pressure, tool sliding velocity, and tool feed.
At the specified optimal parameters, predicted values of output variables: coatings continuity, wear intensity, and relative roughness were obtained.
Established that as the pressure increases to 60 MPa, there is a decreasing of wear intensity, however further pressure increasing has a tendency to wear intensity increasing. With specified velocities of approximately of 2,0 m/s, there is an increasing in coating continuity until it reaches maximum values, further increase of sliding velocity has a negative impact on the coating continuity due to insufficient filling of microrelief and poor formation of antifriction coating. Increasing the feed in the entire range has a negative impact on the relative roughness, therefore minimum feed values should be maintained during the treatment.
