Lathing Processing Dosage Trends Identifying Based on Current Signal

It is extremely meaningful to identify the processing dosage which directly influence the processing time, quality and other processing factors. In order to obtain the trend of lathing processing dosage, ordinary horizontal lathe was researched using the power signal frequency spectrum method, through the frequency distribution and the differences of amplitude, the trends of lathing processing dosage was identified. The collected current signal was turned into power signal first, when the cut depth is large, it is able to identify the trends of processing dosage through the fluctuations of the power signal, but when the cutting depth is small, compared to the power signal of idling state, there is not obvious difference to distinguish them. In this case, the frequency distribution and the differences of amplitude of the power signal were introduced.
