研削過程におけるスペクトル解析

抄録

In this paper, the spectral analysis of the transcribed surface profile of a wheel in relation to the progress of grinding process is studied. Based on this analysis, the quality of grindability between the wheel and the workpiece, and the infuluence of work speed in relation to the tool life of a wheel are reported.
The main results obtained are as follows. 1) The transcribed surface profile obtained from a grinding wheel just after the dressing has a very strong correlation, and the highest value of the spectral density is found at the wave length just corresponding to the dressing feed.
For convenience, this periodic element is named S_p (λ). As the grinding process proceeds, the correlation becomes weak and the S_p (λ) decreases. Especially this tendency is remarkable when the combination of the wheel and the work material is not suitable. 2) As far as this experiment is performed, the S_p (λ) decreases slowly and the value of the S_p (λ) on the point of the tool life of a wheel becomes small according as the work speed increases.
