Der Beitrag beschreibt einen Ansatz zur simulationsgestützten Nachbildung des Schwingverhaltens dünner scheibenförmiger Werkzeuge bei hochfrequenten Wechselschwingungen. Der Ansatz wurde primär für Kreissägewerkzeuge entwickelt, um diese bereits in der Konzeptphase so zu gestalten, dass diese sich für die ultraschallüberlagerte Zerspanung bei bis zu 20 kHz einsetzen lassen.   This article describes a model which helps to recreate the vibration-behavior of thin circular-shaped cutting tools influenced by ultrasonic vibrations. The model is primarily developed for the conception of circular saw-blades to support the geometric adaption for the ultrasonic-assisted-cutting process (UAC) at 20 kHz.

RS (residual stresses) represent the main role in the performance of structures and machined parts. The main objective of this paper is to investigate the effect of feed rate with constant cutting speed and depth of cut on residual stresses in orthogonal cutting, using Tungsten carbide cutting tools when machining AISI 316 in turning operation. AISI 316 stainless steel was selected in experiments since it is used in many important industries such as chemical, petrochemical industries, power generation, electrical engineering, food and beverage industry. Four feed rates were selected (0.228, 0.16, 0.08 and 0.065) mm/rev when cutting speed is constant 71 mm/min and depth of cutting 2 mm. The experimental results of residual stresses were (-15.75, 12.84, 64.9, 37.74) MPa and the numerical results of residual stresses were (-15, 12, 59, and 37) MPa. The best value of residual stresses is (-15.75 and -15) MPa when it is in a compressive way. The results showed that the percentage error between numerical by using (ABAQUS/ CAE ver. 2017) and experimental work measured by X-ray diffraction is range (2-15) %.
