<jats:p>In this study, the effect of cutting fluid on tool wear in finished surface formation area was investigated when turning alloy 304 with a TiN coated carbide tool under different lubricant conditions and the transition of surface roughness caused by tool wear was investigated. In the case of water-soluble cutting fluid, the higher concentration emulsion caused a smaller wear width <jats:italic>VB</jats:italic> and larger <jats:italic>VB</jats:italic>’”. In the case of oily cutting fluid, the lower co-efficient of friction oil caused a smaller wear width <jats:italic>VB</jats:italic> and larger <jats:italic>VB</jats:italic>’”. In both cases of water soluble and oily cutting fluid, the cutting fluid of lower coefficient of friction caused a larger wear width <jats:italic>VB</jats:italic> in milling at the feed rate of around tool edge roundness. This tendency was consistent with the wear width <jats:italic>VB</jats:italic>” and <jats:italic>VB</jats:italic>’” in turning. In both cases of water soluble and oily cutting fluid, the cutting fluid of lower coefficient of friction caused a larger cutting force volatility. The feed marks were more irregular in lower coefficient cutting fluids.</jats:p>
