Experiments on the Cutting Process in Ice
Cutting tests were carried out on natural lake ice using parallel motion, orthogonal cutting tools. Parameters that varied were cutter rake angle, from -5 to 30; cutter velocity from 4.0 to 10.6 in./s; and depth of cut from 0 to 0.200 in. The average horizontal and vertical components of force and t...
