IPC: B23Q11/00
Filed: 2007-05-24
Abstract: <P>PROBLEM TO BE SOLVED: To effectively suppress chatter vibration in a short time.  <P>SOLUTION: The Fourier analysis for the acceleration of the chatter vibration is carried out in S1, and the maximum acceleration and its frequency are calculated in S2. Next, the maximum acceleration is compared with a preset specified threshold value in S3. When the maximum acceleration exceeds the threshold value, a k value and the information about a phase are calculated in S4 from the chatter frequency, the number of the cutting edges of a tool, and the rotational speed of a rotary shaft. Next, the information about the phase is compared with a preset constant in S5. When the information about the phase is larger than the set constant, a k1 value is calculated in S6 based on a changing expression (1). On the other hand, when the information about the phase is smaller than the set constant, the k1 value is calculated in S7 based on a changing expression (2). Then, the optimum rotational speed for minimizing the change of the rotational speed is calculated in S8 from the chatter frequency, the number of the cutting edges of the tool, and the k1 value.  <P>COPYRIGHT: (C)2009,JPO&INPIT
