Process fluids are used primarily for their cooling and lubricating effect in machining. Many ways to improve their performance have been proposed; the analysis of some of them is provided in the paper. The effect of high pressure cooling has been investigated with regard to chip formation and tool life. Standard and for high pressure application particularly designed indexable cutting inserts were used with fluid pressure 1.5 and 7.5 MPa. The pressure effect on tool life at different feed rates was observed as well. Not each cooling pressure value or machined material showed favourable chip formation. Tool life though has improved significantly while machining with a lower feed rate.

Keywords: tool; indexable insert; high pressure cutting fluid application; cutting parameters; tool life
