“…As it has been noted in [1,2] durability, corrosion and fatigue resistance of products, which are utilized in severe and corrosive environment are determined not only by rational constructions and physic-technical material properties but also depend on processing modes during finishing operations. Two parameter groups of surface quality are denoted [4,10]: geometrical parameters and parameters determining physical surface properties. The detail surface is always rough due to its processing.…”

“…In this case micro relief is considered a regulated system [2,3], influenced by external ultrasonic impact with the specified regulated parameters, determining an effect of enhanced service properties of machine parts. By trial and error of technological parameters we can reduce surface roughness and enhance surface smoothness 4-8 times [9,10]. Surface smoothing by vibro treatment has several advantages comparing with other surface-plastic deformation processes by productivity, simplicity, and universality of utilization.…”

Fatigue, corroding and tribological properties of machine parts are mostly determined by surface quality formed during finishing operations. One of the most effective ways to form the required surface is by ultrasonic smoothing. The article presents experimental results of ultrasonic surface smoothing for workpieces of two types of steels 17Х18N9Т and 20Х1М1F1ТR. The experiments were conducted on the turning lathe with the experimental ultrasonic technological complex. The variables were workpiece rotational speed, feeding speed, clamping force and ultrasonic power treatment. D-optimal plan of Hartley-Kono was used during the experiment. Dispersion-regressive analysis of the experimental data revealed the relation between the surface roughness and processing regime modes. Feeding lowering decreases the surface roughness for both steels. To decrease the surface roughness of 20Х1М1F1ТR steel it is necessary to increase power of ultrasonic treatment simultaneously with clamping force decrease. For steel 17Х18N9Т clamping force results in surface roughness lowering that is why ultrasonic power is not significant. Partial correlation coefficient analysis revealed that micro profile height for steel 20Х1М1F1ТR is determined by feeding speed. For austenitic steel 17Х18N9Т feeding speed and clamping force are equally important factors. During the experiments the surface roughness decreased from 1.5 mkm to 0,1-0,2 mkm with ultrasonic treatment, that is more than 10 times.
