Assurance of accuracy of longitudinal section of profile surfaces milled at high feeds

Abstract

The article considers the process of profile milling of extended surfaces with shaping cutters and independent factors determining the dominant influence on the optimization parameter as well as the deviation of the longitudinal section profile of the product. One-factor experiments were conducted on the basis of which the operating conditions of the technological system were further determined under which the processing process proceeds steadily with a minimum level of vibration. Under these operating conditions of the technological system, multifactorial experiments were performed. The multifactorial experimental model of the optimization parameter as a function of the elements of the cutting mode was obtained on the basis of which the deviation of the profile of the longitudinal section was simulated in a wide range of values of the independent factors of the profile milling process. The statistical processing of the data of the planned and realized multifactor experiment was carried out, the multifactor model was tested for adequacy and its graphical interpretation was presented which allowed obtaining the scientific data necessary for the well-founded construction of intensive operations of workpiece profile milling.
