Coated cemented carbide inserts were applied in up- and down-milling stainless steel for monitoring the tool wear at repetitive cutting loads of various magnitudes and durations. Via impact tests with adjustable force signal characteristics, the applied loads can simulate the developed ones in milling when the cutting edge penetrates the workpiece. The attained tool life of coated inserts was associated with the developed maximum strain and its rate in the film during milling. The latter factors were correlated to the strain and strain rate dependent coating fatigue endurance. Based on these issues, the tool life was explained in various milling kinematics.
