In some special surgeries, e.g., burnt necrotic tissue removing process and skin grafting process, the cutting edge of scalpel moves along the tangential direction of tissue surface to achieve the cutting of biological tissue. This cutting pattern, which is similar with the turning process of metal material, is essential different from the vertical cutting presented in literatures. As a first endeavor,...
A mechanistic model is developed to predict micromilling forces with flat end mill for both shearing and ploughing-dominant cutting regimes. The model assumes that there is a critical chip thickness that determines whether a chip will form or not. Numerical method is extended to predict the chatter stability in micro end milling, which is performed based on the proposed cutting force model. The simulating...
