Influence of Thermoplastics Advanced Ultrasonic Treatment on Treated Surface Roughness After Turning

The results of experimental studies of a new method for turning billets from thermoplastic polymers such as caprolon and fluoroplastic are presented. The technical essence of the method is in the workpiece advanced processing by ultrasonic vibrations using preliminary machining. Experimental studies were carried out on a lathe which is equipped with an ultrasonic oscillatory system. Roughness level profilograms of the caprolon and fluoroplastic-treated surfaces are used for visual and operational control of the turning process. The results of the experimental verification of the developed method confirmed the expediency of its implementation since the use of advanced ultrasonic treatment during turning of thermoplastics leads to a decrease in the roughness level of the treated surface of the part as evidenced by the values of roughness parameters and the type of chips obtained.
