swine lamina milling

We carried out swine lamina milling experiment and collect force signal during milling process, to establish data set for model training. A total of 36 segments of thoracic and lumbar spine, which included 36 vertebral plates, of fresh adult swine purchased from the market were selected. We tested 12 milling conditions with 6 times repeated experiments for each condition. In terms of ultrasonic scalpel, we designed 3 kinds of milling power: 100 $\%$, 80 $\%$, 60 $\%$, while for grinding drill, 3 grinding speeds including 10000r/s, 15000r/s, 20000r/s were chosen. Each milling instruments can move in speed of 0.5mm/s and 1 mm/s.
