Analysis of Characteristics of Movement and Stress in Centerless Superfinishing

Abstract:

At present, many of the problems about precision guarantee in centerless sunperfinishing have been solved due to the forming system design in the process of machining and machine tool adjustment. But the precise forming trajectory cannot guarantee the given accuracy. Because uneven movement of the blank in the process of processing owing to the comprehensive influence of motion and force, resulting in, causing changes in metal removal. Now, there has been no the geometry kinematics theory model because lack of the study of the physical reasons for the above phenomenon. So improving accuracy of centerless superfinishing depends on the analysis of the description of movement and stress parameter analysis and equipment parameters adjustment. The stress distribution of the blank in centerless superfinishing process was studied. Force balance equation of it was established. Characteristics of movement of the blank relative to the roll and oil stone was analyzed. Found the friction condition of the blank steady rotating contact with the roller. Some of machine tool equipment adjustment parameters which have great influence on the stability of motion were analyzed. A few methods improved the centerless superfinishing precision by analysis of the movement description and Mechanical processing parameters and Machine tool equipment parameters adjustment were analyzed.
