“Study of the Machinability of AISI P20 and AISI H13 1010 by Drilling Test with Constant Axial Force at the Drill Tip

Machinability in general terms, is the ease with which a material can be machined through chip removal, according to a set of cutting conditions. It is necessary to have a quick methodology for the comparison of machinability between materials in order to choose, which of them is the optimum according to the working conditions given by the designer. To carry out a comparative study of the machinability of AISI P20 and AISI H13 Mold Steels by means of the drilling test with constant axial force at the tip of the drill bit. In order to perform machinability tests, a drilling machine was adapted to perform the machinability tests between two steels widely used in the construction of machine parts and components, AISI P20 and AISI H13. In this type of test, little time is invested in machining and little material is used, obtaining the optimum cutting conditions and machinability values.
