영문 초록

  Total arthroplasty is one of the most active applications of robotic surgery in orthopedics. The main job of orthopedic surgical robot is bone cutting with milling tools. A reliable method for predicting milling forces may allow us to design more intelligent and effective systems. In this study, we have developed a prediction models for milling forces during the orthopedic surgery by expanding the orthogonal bone-cutting model. To verify the model, we milled fresh bovine bones with a medical round bur and measured cutting forces in various cutting conditions. The developed model can predict milling forces about cutting depth below 0.5㎜ with a feedrate 2~9.8㎜/s, and 0~10% mean error and 13~25% of standard deviation. This model can be applied as a control algorithm of orthopedic robotic surgery, and also as a safety checking system. The model can be interpreted as general design criteria for new robotic system.
