The milling forces under different micro milling parameters are recorded during \ufe63 test. The peak value of milling force corresponding to the maximum cutting thickness in the tool rotation cycle is taken as the test result, and the measurement results of X, y and Z components are shown in Figure 4. At the same milling depth, the milling force increases with the increase of the feed rate FZ of each tooth. The main cutting force Fx and the feed force Fy rise relatively gently. When the milling depth is ap=2 m and 4 m, the main cutting force Fx rises from 0.44N and 0.92N to 1.34N and 2.05N respectively, and the feed force Fy increases from the 1.34N and the second to the “Ho” and “the”; the axial force increases by a large amplitude, from the “Qi” and “the” to “the”. Similarly, the increase of milling depth will also lead to the increase of milling force. The axial force FZ in the three-way component is sensitive to the milling parameters. The reason is that the feed rate of each tooth FZ in micro milling is smaller than the edge arc radius \u03b3 \u03b2 of the micro milling cutter, which makes the contact area between the back face of the bottom edge of the micro milling cutter and the workpiece relatively large, and the friction force on the back face accounts for a large proportion in the milling force.<\/p>\n\n\n\n
