臺達變頻器在切削力測量實驗中的應用

摘要：切削力是金屬切削中的重要現象之一，與切削速度呈駝峰曲線關系。為了使車削中的切削速度不受工件直徑變化影響，而得到清晰完整的駝峰曲線，采用臺達變頻器對機床主電機進行無級調速，從而使主軸轉速由主電機工作頻率和調速手柄共同決定。實驗結果表明無級調速可得到較理想的駝峰曲線。 敘詞：臺達變頻器 機床 無級調速 切削力 駝峰曲線 Abstract：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.
