Abstract : An investigation of the internal and external sources of vibration in machining operations which impair the performance quality of conventional machine tools was conducted. Particular attention was give to the surface finish of workpieces and the deflection of specific machine tool components. A literature survey on machine tool vibrations was abstrated. All experimental work was carried out under such operating conditions as can be found in an average precision machine shop. The measuring instruments used were standard items except in the case of a special surface analyzer.. Sources of mechanical vibrations in machine tools can be determined satisfactorily with limited instrumentation but a thorough understanding of machine tool functions and metal cutting technology is necessary. Forced and self-excited vibrations can occur simultaneously with both having a detrimental effect upon surface finish and dimensions. (Author)
