“…The surface roughness, material removal rate, kerf breadth, and dimensional deviation are all significantly influenced by pulse-on time compared to other parameters [27,28]. An increase in pulse time frequency and current density are the two factors that contribute to high deposits of materials on the electrode [29].…”

The current study investigates experimentally the Wire-cut Electrical Discharge Machining (WEDM) of 20MnCr5 steel. WEDM is used to manufacture gears, shafts, spindles, camshafts, and other mechanical controlling components. In order to analyse the three performance parameters such as profile error, material removal rate (MRR), and surface roughness (SR), five WEDM parameters were employed in the trials: wire feed (Wf), wire tension (Wt), servo voltage (SV), discharge arc-off time (Toff), and arc-on time (Ton). When compared to the effects of arc on time and servo voltage on MRR, wire feed rate and tension are less important. Higher arc-on time and servo voltage have produced more profile inaccuracy. Decreased wire tension values cause the surface roughness to be more significant and result in lower roughness. As the voltage increases, an uneven surface with a large globule and a deep crater forms on the machined surface. The recast layer becomes thicker at a higher arc on time and servo voltage.

“…The second is the method of comprehensive plastic deformation (Severe Plastic Deformation). The overall plastic deformation process is the process of forming metals in which plastic strain which is given to the metal or material being processed is very large so as to produce a smooth grain (ultra fine grain) [17]. The deformation process is done, among others, can be done by way of the hot working or cold.…”

Metal reinforcement that has an impact on improving mechanical properties can occur in various ways, including by strain hardening mechanisms, solid solutions, second phase, prespitations, disperse, grain refinement and texture. In recent years, another method has been developed to obtain good mechanical properties without adding alloy elements, namely by the method of comprehensive plastic deformation (Severe Plastic Deformation). The purpose of this research is to conduct a study of rolling using medium carbon steel with a treatment temperature above recrystallization, rolling rate, sintering time, cooling media as an effort to develop and design new innovations about steel structures being rolled. The study of developing rolling techniques that can be applied in industry and can be applied as learning material / media in higher education requires structured research stages. The best impact value from this temper process is a temperature of 550 ° C for 1 hour where the impact value is 1.58 J / mm² with air conditioning media. In the rolling process above the recrystallization temperature 800 ° C deformation 20% the impact value is 1.7 J / mm² where the toughness indicates a ductile fracture while the deformation is 10% the impact value

Demand on high accuracy product are getting raised recently. Wire Electrical Discharge Machining (EDM) is one of non-conventional machining who can produce high accuracy product with two axis. By using sparks from electrical energy to erode material in conductive fluid, called electrode fluid. A spur gear with JIS B 1701:1973 standard has specific criteria, including dimension and mechanical tolerance. DIN 1.2378 is a medium carbon steel which is common to use as a gear in automotive industry. This martial is like the ordinary one, but with an extra nickel. The aim of this research is to observe how far effect Wire EDM parameter process such as pulse on time, open voltage, pulse current and wire tension affected on involute profile error of spur gear shape with Taguchi matrix orthogonal L18 methods as experimental design. From research we concluded that the most involute profile error is a minus profile, it means involute curve on actual gear smaller than ideal involute curve. The smallest dimensional distortion involute profile error is 79μm and the highest 125μm. Process parameter pulse on time, open voltage, and pulse current has directly proportional to involute profile error, while wire tension has inversely proportional to involute profile error.
