“…Additionally, its hardness up to 62 ± 2HRC makes it charming to use [9]. However, tool wear and cost are encountered in the processing of hard materials with traditional methods, and it is difficult to obtain good surface quality [10][11][12]. Lima et al focused on the turning of hardened AISI 4340 high strength low alloy steel and AISI D2 cold work steels (58HRC) using a coated carbide insert and a polycrystalline cubic boron nitride insert cutting tools.…”

The goal of this project is to investigate the effect of the spindle speed and feed rate used in milling X153CrMoV12 cold work steel by X5070 blue coated solid carbide end mill on surface roughness and hardness of the workpiece. For this purpose, 0.2 mm material was removed in one pass without using refrigerant with the machining parameters of 2000, 2500, 2800, 3000 rpm spindle speed and 160, 180, 200, 240 mm/min feed rate. As a result of the tests, the topographic structure, surface roughness, surface hardness and microhardness of the machined surfaces were determined by Leica DMS300, Mitutoyo SJ 210, HRS-150 digital rockwell hardness tester and microhardness tester Future-Tech FM-700, respectively. As the feed rate increased at a constant 2800 rpm spindle speed, the surface roughness (SR) increased as the amount of metal removed per unit time increased. As the spindle speed increased at a constant feed rate of 180 mm/min, the amount of chips for the next cutting decreased, as the cutting blade removed more chips with each turn, and therefore the surface roughness decreased. The effects of spindle speed and feed rate machining parameters on the surface hardness were not much, and the hardness value before and after the process was measured between 60-62 HRC. However, it was determined that the microhardness value decreased due to the use of heathardened steel as well as the heat generated by the milling parameters in the regions 50-350 µm deep from the machined surface.

“…Some manufacturing methods are needed to make these hard materials suitable for the place of use (Chen et al , 2020). It is very difficult to process this high hardness materials by conventional cutting and processing methods because of high tool cost, wear and precision problems (Vellingiri et al , 2020; Johny and Thiagarajan, 2020; Pramanick et al , 2020). All kinds of metal materials with high hardness can be cut with high measurement precision and surface quality provided that the correct processing parameters are selected by electric discharge machine (EDM) technology widely used in the industry but still developing (Lei et al , 2020).…”

Purpose Wire electric discharge machining (WEDM) is a non-conventional machining process, which is used for cutting parts of civil and military aircraft, rotorcraft, satellites and spacecraft. The cold work steel X153CrMoV12 is used in molds that are needed to produce plastic and metal parts used in these areas. It is only possible to produce parts with precise dimensions and quality with the use of mold steels with sensitive surfaces. The purpose of this study is to analyze X153CrMoV12 material by cutting it with WEDM method in precise dimensions. Design/methodology/approach The effects of varying cutting parameters on the size of the finished product, surface roughness (SR) and surface hardness were determined by making rough in one pass and precision cuts in different passes. Nikon SMZ745T, Mitutoyo micrometer, Mitutoyo SJ-210 and Insize ISHL-P100 were used for macro-analysis, dimensional control, SR and surface hardness, respectively, to determine the cut qualities. Findings According to the hardness measurement results obtained from the steel surface before cutting and from the cut surfaces after cutting, there was no significant change in the surface hardness owing to the use of heat-treated steel. Increasing the wire tension as a result of the increase in the number of cutting passes and the decrease in the amount of rough stock left for the final cut increased the cut quality. Cutting precision has increased by preventing vibration of the wire with zero upper and lower water pressure required for slag cleaning. Originality/value There are many studies on WEDM in the literature, but there is no similar study emphasizing the importance of the processing parameters such as the number of cutting passes and rough stock amount. In this study, cold work steel with a hardness of 56–60 HRC was machined as rough cut in one pass, rough and fine cut in double pass, double fine cut after one roughing in three passes. As a result of the cuts, 3 µm measurement precision and 0.998 Ra SR were obtained as well as there was no hardness change in the cut surfaces.
