Abstract When sawing a log into lumber or other products, the saw blade removes material to separate wood fibers between resulting two parts, loss of that is commonly referred as kerf. Thicker kerfs result in greater waste and less available produce lumber. Over past decades, with advancement materials technology, thickness has decreased. However, reduction owing kerf may not always translate s...

The focus of today’s machining industry is on how to maintain high productivity and low cost achieved by tool life during the operation. Laser cutting considered right solution because it offers speeds up 170000 mm/min through a non-contact process regardless workpiece material hardness. aim this study analyze effect speed surface texture aspects namely roughness, kerf shape, dross height stain...

Increasing demand and resource overuse has prompted the exploration of spent secondary materials as a primary raw material for variety applications, leading to more sustainable environment. Spent electric grid ceramic insulator, one waste industry, good hardness strength. It can be reused value-added in Abrasive Water Jet Machining (AWJM) industry. The present work deals with generation cost-ef...

Al-Mg-based composite is used in producing a variety of components. To improve the machinability composite, MoS2 added. For characterizing machining different wt.% (2, 4, and 6) are added as reinforcement. Wire Electrical Discharge Machining (WEDM) process performed to analyze kerf width surface roughness. Due complex nature WEDM process, necessity for its optimization through use innovative me...

Bu çalışmada konvansiyonel yöntemlerle delinmesi maliyetli ve zor olan yüksek sertlikteki (60-62HRC) X153CrMoV12 soğuk iş takım çeliğine elektro erozyonla hızlı delik delme tezgahında 3 mm pirinç elektrotlar kullanılarak delikler delinmiştir. kapsamda üç farklı amper (5, 6, 7 A), voltaj (1, 2, V), altı ark süresi (18, 22, 24, 26, 28, 29 μs), dört bekleme (3, 8, 10 μs) parametrelerinin işleme de...

In this study, the eff ects of cutting parameters on kerf and surface roughness were experimentally investigated in WEDM. Al 7 475-T7 351 alloy was selected as the work material to conduct experiments. The factors selected for the optimization are the pulse on time, table feed rate and the wire speed, each of the factors in three diff erent levels. An optimal parameter combination of the WEDM p...
