Özet
ObjectivesTo introduce and evaluate the performance of a novel tool holder design for turning operations on a CNC lathe. The study aimed to address the pervasive challenge of vibration in turning operations, which influences tool wear and the quality of the final surface finish.MethodsThe experimental assessment involved comparing the new tool holder with a conventional steel one under varying cutting parameters, including feed rate, cutting speed, and depth of cut. A computer numerical control (CNC) lathe was utilized for the experiments. An analysis of variance (ANOVA) was employed to dissect the impacts of different cutting parameters on both vibration levels and surface roughness.ResultsThe experimental results highlighted significant advantages offered by the new tool holder. It achieved a remarkable reduction in vibration levels, ranging between 25.4 and 48.7% compared to the steel tool holder. Additionally, the new tool holder led to a noticeable improvement in surface roughness, with a reduction in the range of 21.5 to 31.5%. The ANOVA analysis underscored the depth of cut as the most influential parameter, with a paramount effect on both vibration amplitude and surface roughness.ConclusionsThe research strongly recommends the adoption of the new tool holder, particularly in scenarios requiring extended overhangs. The innovative design demonstrated superior performance in reducing vibrations and improving surface roughness during turning operations. Furthermore, the study explored the application of shape memory alloys in turning cutting tools, emphasizing their substantial role in vibration reduction.
