This paper presents, the experimental study has been made to optimize the process parameters during machining of H-13 by wire electrical discharge machining (WEDM) using Taguchi L9 orthogonal array method. Following input process parameters of WEDM [Pulse-On time (TON), Pulse-Off time (TOFF) and Wire Speed rate (WS) and Wire Tension (WT)] were chosen as variables to study the process output in ...

In this study, the effects of cutting edge geometry, workpiece hardness, feed rate and cutting speed on surface roughness and resultant forces in the finish hard turning of AISI H13 steel were experimentally investigated. Cubic boron nitrite inserts with two distinct edge preparations and throughhardened AISI H13 steel bars were used. Four-factor (hardness, edge geometry, feed rate and cutting ...

Laser-based flexible fabrication (LBFF), a solid free form fabrication (SFF) method based on laser-cladding process, was developed as an alternative to conventional machining methods for producing dies and molds. LBFF is similar to processes such as LENS with additional features including shaped beam profile, quasi-coaxial powder delivery, and functionally graded materials. It uses a high-power...

In the present study, a modified H13 hot-work tool steel (M-H13) was fabricated by laser beam powder bed fusion (LB-PBF). The effect of two types post processing, direct tempering from as-built condition (DT) and conventional quenching followed (QT), on microstructure mechanical properties evaluated. typical in QT tempered martensite with carbides along lath boundaries. DT condition, melt pool ...

In this study, machinability tests on Assab Korkmaz Orvar Supreme (1.2344 ESR, AISI H13 Premium) hot work tool steel widely used in industry were carried out. Machinability tests were carried out through single point turning method at eight different cutting speeds (120, 160, 200, 240, 280, 320, 360 ve 400 m/dak), four different feed rates (0,05; 0,10; 0,15 and 0,20 mm/min) and 1 mm depth of cu...
