摘要
A large number of parts have deep holes, therefore, rotary cutting tools, which represent relatively long and thin columns are used for holemaking. In this article we analyze the behavior of such tools under the influence of an axial compression load, in our case, the axial cutting force F-p, which differs fundamentally from the compression of short tools. Moreover, experience shows that when the cutting force Fp reaches a certain critical value equal to F-kp,, a long straight column becomes unstable.
