摘　　要：切削力是金属切削中的重要现象之一,与切削速度呈驼峰曲线关系。为了使车削中的切削速度不受工件直径变化影响,而得到清晰完整的驼峰曲线,采用台达变频器对机床主电机进行无级调速,从而使主轴转速由主电机工作频率和调速手柄共同决定。实验结果表明无级调速可得到较理想的驼峰曲线。Cutting force is one of the important phenomenons,and presents the relation of hump curve.However,cutting speed is effected by workpiece diameter.For obtaining a legible and perfect hump curve,a Delta transducer was applied to carry out stepless speed regulating of the main electromotor of machine tool.Consequently,the main shaft speed was decided by the electromotor working frequency and speed selection handles.The experiment result shows that the legible and perfect hump curve can be achieved under the stepless speed regulating.
