Effect of Wear on the Vibrating Behaviour of the Tool at Turning CW724R Alloy

The development of new materials and technologies also significantly affects traditional methods of component production, as it forces companies to increase the efficiency of the production process and thus remain competitive. This pressure also brings new challenges in the field of machining. The article deals with the influence of wear on the vibration behaviour of the tool when turning CW724R alloy. The aim of the research is to know the frequency response of the system to different sizes of tool wear, which causes deterioration of the quality of machined parts and instability of the entire cutting process. A specific method of artificial wear of cutting tool was applied to determine the vibration behaviour of a worn tool. To reduce the number of experimental measurements, the methodology of the orthogonal non-rotating composition plan was chosen. The matrix of two independent variables (cutting speed versus artificial wear) was selected to evaluate the relationships between them under conditions of the constant depth of cut and feed, which was processed by the multiple linear regression methodology. Finally, a dependence of vibrations on cutting speed and wear rate for evaluated material was plotted in a spatial graph.
