Hard machining is a difficult task. High cutting forces and tool life are some of the main points to be considered in relation to this type of process. As far as tool life is concerned, the proper selection of cutting parameters becomes a priority. Cutting speed is the parameter that most influences the life of a tool. In this work, the wear of TiAlCrN coated carbide inserts in the end milling of AISI O1 steel tempered and quenched at 57HRC is evaluated. Best results were obtained for a cutting speed range of 50 m/min, where longer tool life has been obtained. The limiting cutting speed range for the process is 80 m/min where excessive chipping and tool breakage are checked. |
