Experimental procedure Coated carbide inserts of

Coated carbide inserts of ISO designation CNMG 120404-MF with 1105 grade and chip breaker geometry by Sandvik Company were used for the experiments. The cutting inserts were clamped on to Purmorphamine left hand tool holder having ISO designation PCBNL 2020 M12, which was made by SECO Company. For machining of the workpieces, a CNC lathe (EMCOTURN 242 TC, Austria) was used. The machine has a maximum spindle speed of 4500 rpm and maximum power of 13 kW.
