EXPERIMENTAL EVALUATION OF WEDM MACHINED SURFACE WAVINESS

Acta Polytechnica, 2016
Wire Electrical Discharge Machining (WEDM) an unconventional machining technology which has become indispensable in many industries. The typical morphology of a surface machined using the electrical discharge technology is characterized with a large number of craters caused by electro-spark discharges produced during the machining process.

Effect of Milling and Wire Electric Discharge Machining on Recast Layer Formation and Tensile Behavior of Metallic Materials

MetalMat, EarlyView.
ABSTRACT Machining of materials is an invaluable technique to give specific shapes and dimensions of desired materials. Different machining processes give rise to different surface characteristics that include not only surface roughness but also specific surface morphology, such as the recast layer.

Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

steel research international, EarlyView.
Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61
