実用的な安定限界式の提案

Self-excited vibration in grinding caused by the regenerative effect of workpiece surface has been investigated by many researchers. In those works, however, the limit of stability has not been given n the form of practical equation. In this papar, a method to obtain the limit of stability by measuring the static grinding force and the frequency of small amplitude in grinding process is proposed. The results obtained are as follows. (1) The stability limit equation is given in a practical form, i. e. as a function of workpiece speed, depth of cut and grinding wheel width. (2) The calculated results of the limit of stability which are obtained by using informations in grinding process agree well with the experimental results.
