The length, width and thickness of a steel sample are 400 mm, 40 mm and 20 mm, respectively Its thickness needs to be uniformly reduced by 2 mm in a single pass by using horizontal slat milling. The milling cutter (diameter: 100 mm, width: 50 mm) has 20 teeth and rotates at 1200 rpm. The feed per tooth is 0.05 mm. The feed direction is along the length of the sample.
