Study with Stainless Steel AISI 630 of Tool Wear in External Turning Operations
This study starts from a firm’s needs to improve manufacturing costs and times in an external turning operation with the material according to the standard AISI 630 (martensitic stainless steel, hardened by precipitation), with a hardness of 355 HB. It has been developed a basic factorial design of experiments with two factors (cutting speed and feed per revolution), with constant depth of cut and two levels, with three central points. This experiment has resulted in the obtaining of the machined meters from a tool life criterion, which has limited basically the tool flank wear, VB = 0,2 mm. The balance between the tool wear, maximum machining length and the minimum machining time has been considered from the analysis of the results.
