Abstract The article considers the physical model of the deformation interaction of the tool with the surface being treated in the process of surface-plastic deformation by diamond smoothing. A step-by-step diagram of the formation relief of the surface of the part during diamond smoothing with elastic and rigid fastening of the tool is presented. Given the general stationarity of the smoothing process under steady-state conditions, two unsteady periods are distinguished, characterized by instability of the surface formation conditions. The reasons and conditions for the unevenness of the process are illustrated by the surface deformation schemes for elastic and rigid fastening of the diamond tip. The sequence of stages of the formation of the surface layer in the initial period of the unsteady process is shown, when the tool comes into contact with the processed surface, and in the final unsteady period, when the tool leaves the contact interaction with the workpiece. At the same time, features are noted in the deformation pattern of the transitional periods of treatment with an elastic and rigid tool. The instability of the parameters of the contact interaction of the tool and the part in the unsteady periods of diamond smoothing causes the probability of the formation of defective areas on the treated surface. Expressions are given for determining the relief parameters of transitional sections of a smoothed surface and an estimate is given for the length of the transitional zone at the tool input in contact with the part and at the output from the contact, depending on the hardness of the processed material. The probable length of the transition sections, characterized by a deviation of the diametrical dimensions and surface shape, should be taken into account when designing the functional elements of the part and the technological process of finishing and hardening smoothing.
