Effect of lubricant on tool wear in finished surface formation area of rounded nosed tool

Abstract

In the case of water-soluble cutting fluid, the higher concentration emulsion caused the smaller wear width VB and larger VB"'. In the case of oily cutting fluid, the lower co-efficient of friction oil caused the smaller wear width VB and larger VB"'. In both cases of water soluble and oily cutting fluid, the cutting fluid of lower coefficient of friction caused the larger wear width VB. This tendency agreed with the wear width VB"' in turning. In the both cases of water soluble and oily cutting fluid, the cutting fluid of lower coefficient of friction caused the larger cutting force volatility.
