ResumoEarlier work by Pekelharing has shown that in interrupted cutting with cemented carbide cutting tools on steel workpieces the exit failure due to the formation of feet is the major cause of tool failure. A typical industrial operation with these characteristics is face milling. The sensitiviness of a number of commercial milling tools when cutting Ck45 steel was investigated. For a certain range of positions of the cutter relative to the exit face of the workpiece the number of cuts which can be taken until tool failure occurs is nearly zero. This is called the “dangerous zone of exit conditions”. The position of the boundaries between safe and dangerous exit conditions are used to evaluate the sensitiviness for exit failure of milling cutters. The influence of tooldesign and cutting conditions on these boundaries is discussed.
