THE ANALYSIS OF THE EFFECT OF SELECTED TECHNOLOGICAL PARAMETERS ON THE VIBRATION PARAMETERS OF THE MACHINED MATERIAL BY PLASMA CUTTING TECHNOLOGY

Abstract

In plasma arc welding using ultrasound, the ultrasonic vibration acts on the tungsten electrode with the plasma arc and changes its thermal pressure characteristics. It is very important to examine the underlying mechanism of the interaction. In this study, the intention is to analyze and assess the influence of input technological factors on the occurrence and magnitude of mechanical vibration under operating conditions. It analyses the effect of changing the feed rate (200, 700, 1200, and 1700 mm/min) on the plasma machine using two currents (220 and 280 A) on the acceleration amplitude and vibration frequency. From the measured values, graphical dependencies are created and used to compare and evaluate the technical condition of the selected equipment.
