A method of reducing cutting tool wear in a lubricated metal cutting
operation has been developed. An electrical cutting cell is provided
having an anodic conductive cutting tool and a cathodic conductive
work-piece connected to a DC current supply; the lubricant contains
platable wear reducing agents. The lubricant is located to bathe the
contacting interface between the cutting tool and work-piece to constitute
an electrolyte. Next, the electrical current flow through the contacting
interface is controlled to be in the range of 25-500 milli-amps. Lastly,
the cutting tool is moved into and along cutting contact with the
work-piece while current flows there-between to electro-chemically deposit
the wear reducing agents on at least the contacting interface to reduce
cutting tool wear and improve ease of mass removal.
