“…In addition, important study has been done to optimize the WEDM parameters (12)(13)(14)(15)(16)(17)(18)(19). While there is much studies with the weldability of hardox steels (20)(21), there are very few studies on machinability. Some of these studies are related to waterjet (22,23) and laser plasma and plasma cutting (24)(25)(26)(27)(28).…”

In this study, microstructure, mechanical, and conductivity characteristics of Hardox 400 steel were changed with different heat treatments and effect of such characteristics on its machinability with Wire Electrical Discharge Machining (WEDM). Optical microscope examinations were performed to determine various characteristics, and additionally microhardness and conductivity measurements were conducted hereof. L18 Taquchi test design was conducted with three levels and four different parameters to determine the effect of such alterations on its machinability with WEDM and post-processing Cutting width (kerf), Surface roughness (Ra), Material removal rate (MRR) values were determined. Micro changes were ensured successfully by using applied heat treatments. The best kerf value was obtained from sample 6 which was tempered from 350 °C. The microstructure of this sample was composed of commonly α ferrite and few pearlites. The best Ra value was obtained from sample 3 which was tempered from 200 °C. The microstructure of this sample was composed of few α ferrite and commonly pearlites. The best MRR value was obtained from sample 5 which was tempered from 300 °C. The microstructure of this sample was composed of almost equally α ferrite and pearlites. Additionally the most effective parameters on Ra were determined as hardox and current. The most effective parameters on kerf and MRR were determined as time off and hardox.

In this study machinibility of hardox steel plates (welded by plasma and Mag welding) was examined in WEDM. Two different ampere values and two different feed rates were determined for the two different welding types. Depending on these factors ,micro structures, micro hardnesses and resistivity/conductivity values (varying according to heat output) were obtained at the HAZ and WM zones. Then, each of the samples taken from both HAZ and WM zones were cut in the WEDM by using 2 levelled four different parameters. The purpose at this stage is to examine the cutting width (kerf) and surface roughness (Ra) values at the HAZ and WM zones with respect to varying micro structure, micro hardness and conductivity values. At the end of the study, the lowest kerf was obtained with the plasma welded samples whereas the lowest Ra values were obtained with the Mag welded samples. The samples at WM zone are in general are the ones welded by high conductivity sample Mag welding. Whereas in the HAZ zone the samples are the ones welded by high conductivity plasma welding.
