The turning, which consists of the removal of metal from the outer diameter of a rotating cylindrical workpiece, is one of the most common techniques for cutting, especially when finishing the product. The values of the cutting parameters, such as feed rate, cutting speed, and depth of cut, in a turning operation must be selected carefully to improve the profit of operations by enhancing productivity and reducing the total manufacturing cost for each component. A high vibration leads to poor surface finish and reduced productivity and shortens the tool life; therefore, this parameter should be controlled. In this study, an experiment is conducted to investigate the effects of these cutting parameters in the turning process of a workpiece, composed of AISI 1040 steel, using the response surface method. Statistical tools were used to design the experiments. These parameters are optimized by using analysis of variance, regression, and optimization techniques to achieve the condition of minimum vibration and chip frequency, therefore improving the surface roughness after the turning process.

研究和优化工艺参数对AISI 1040钢车削过程中机加工振动的影响

包括从旋转的圆柱形工件的外径上去除金属在内的车削是最常用的切削技术之一，尤其是在精加工产品时。必须仔细选择车削操作中的切削参数（例如进给速度，切削速度和切削深度）的值，以通过提高生产率和降低每个组件的总制造成本来提高运营利润。高振动会导致不良的表面光洁度并降低生产率，并缩短工具寿命；因此，应控制此参数。在这项研究中，进行了一个实验，以响应面方法研究这些切削参数在由AISI 1040钢制成的工件车削过程中的影响。统计工具用于设计实验。通过使用方差分析，回归分析和优化技术来优化这些参数，以达到最小振动和切屑频率的条件，从而改善车削过程后的表面粗糙度。
