Abstract

Background/Objectives: The article considers the outcomes of experimental studies to establish the relationship of surface quality characteristics of parts with constructive and regime parameters of technical levitation devices – Levitation Tool Modules. Methods: The method for controlling microgeometry of the processed surface in the drilled holes with LTM-IV and the technologies applied in Finishing Antifriction Rotary Chamber Processing (FARCP) have been considered. Findings: The results of the experimental investigations of technological capabilities of four types of Levitation Tool Modules (LTM) have been presented. The optimal design and technological parameters of the modules have been established to control the characteristics of the surface layer quality. We have developed and experimentally investigated LTM for high-speed wire-brushing of materials. The possibility of ensuring the part surface quality by transportation of various lubricating and cooling technological means in the treatment zone was examined. The procedure for managing microgeometry of the machined surface of holes based on LTM technology and FARCP was studied. During experimental studies the LTM anti-vibration properties were assessed. In addition to controlling the process of part surface coat formation discussed the possibility of increasing efficiency of tools through the use of levitation tool modules. The presented experimental results suggest a high efficiency and expediency of applying LTM for technological quality assurance of the surface layer of parts. Applications/Improvements: The use of aggregated modular levitation devices will reduce the spread of surface quality parameters on average by 2-3 times and increase the machining quality through adaptive control of LTM based on the stabilization of the energy characteristics of the process.
