The purpose of this study is to investigate the intensity of metal removal rate and surface finish on vibration machining of partitioned working chamber. The article presents the results of studies of metal removal rate and surface finish in different compartments of divided working chamber (partitioned in different sizes) of vibration machining. Experimental studies were carried out on a vibration machine model УВГ- 40, with a divided compartments of working chamber of the total volume 40 dm3 by using working medias of PT 15X15 with a regime of vibration: A = 3 mm; f = 33 Hz and by using a processing liquid – 1.5% solution of soda ash. The prepared samples (for each types of operations 5 samples) were placed in a working chamber of different compartments (compartments differ in size as indicated below in the fig. 1. with a division of partitioned walls) and processed accordingly for 30, 60, 90 minutes. After each treatment in different compartments, the metal removal rate Q, in g, and the surface roughness Ra, in μm, were measured by means of analytical weight AD-200 and surface roughness measuring tester SJ-210 consecutively. Samples are steel 45 and aluminum alloy AVT-1 with cylindrical shapes, steel 3sp and duralumin D16 with plate shapes. As indicated in the given below tables and chart the average metal removal rate and surface roughness varies in the processing of different compartments of the working chambers. The presented research results show that as the size of the compartment in the working chamber decreases, the metal removal rate increases and the surface roughness improves. This study was conducted in Don State Technical University (DSTU) in Rostov on Don, Russia.
