Development of a mathematical model to determine the minimum coefficient of dynamic technological system in the deep face milling

Features of the dynamics of deep face milling with the quantities of allowances 6?8 mm were considered. Periods of tool infeed and exit into the part from the cutting area was analyzed. The mathematical apparatus for determining the minimum dynamics coefficient of technological system was developed. Analytical dependences for determining the loading of the cutting tool were obtained. Characteristics of influence of geometrical parameters on the face milling stability while minimizing the impact on the dynamic tool in the conditions of deep machining were established.
