Experiment Research of Milling Force in High Machining GH4169 Based on MatLab Can Zhao1, a, Wang Xi1, b*, Yubo Liu1, c, Zibiao Wang1d, Yangyang Shi1e 1School of Mechanical Engineering, Heilongjiang University of Science & Technology, NO.2468 Puyuan Road, Harbin city, P.R.China azhaocan_hist@163.com,bdatkream@qq.com, c68572377@qq.com, d836826134@qq.com e464625769@qq.com Keywords: Super Alloy; GH4169; Ceramic Cutting Tool; Milling Force; Milling Parameters Abstract: Consider to the properties of super alloy GH4169, planning the milling experiment with ceramic cutting tool, which is aimed at studying the milling force of different parameters in each direction based on the software of Labview and KISTLER three-component dynamometer.
Through the analysis on the influence and mechanism of cutting parameters to milling force, offering the meaningful theory support to the practice. 1 Experiment Devices and Ways The work piece material of experiment is nickel base super alloy GH4169, and its physical properties as the table 1 shows; the machine tool is EMCO FAMUP MC120-60 four-axis milling center as the figure.1 shows; the tool is the machine clamp type tool which the diameter of the cutter is 64mm, the helix angle is 0°, and the caster angle is 6°, in addition, the type of blade is Salon cc6060 ceramic tip, and the table 2 describe its parameters clearly.
2.3influence of radial cutting depth to milling force When chose the milling speed v=864m/min, feed per tooth fz=0.1mm and axial cutting depth ae=31.5mm, from the figure.6 depicts, the trends of milling force Fx, Fy and Fz are tend to decline after rise, then rise again, Fx and Fz reach to the minimum value of 1098.4 N and 625.8N at the radial cutting depth ap=0.5mm, while Fy reaches to the minimum value of 1158.4N at the radial cutting depth ap=1.3mm. 2.4establishment of milling force empirical formula Studies reveal that formula of complicated exponential relationship could explain the influence of milling parameters to milling force [3], on account of the discontinue blades milling, the milling force has the nature of periodic pulsation, therefore, milling force models of X,Y and Z direction as the follow shows: Fx=Kxapa1fza2va3，Fy=Kyapb1fzb2vb3，Fz=Kzapc1fzc2vc3 (1) In Formula: Kx，Ky，Kz——Coefficient relates to work piece material
