In Wire Electrical Discharge Machining (WEDM) the breakage of the cutting tool (the wire) reduces the process performance and the required accuracy. Previous works of authors showed that the behavior of the basic signals of the process (current and voltage) can be employed to detect degraded situations that can lead to wire breakage. In particular, different types of degraded behaviors in two c...

Micro-electric discharge machining (μ-EDM) is an important manufacturing process that is able to produce components and tools with micro-features. Improvement to this process has resulted in the use of powder mixed dielectric (PMD), which results in better surface quality and faster machining time. However, the presence of conductive powder in the dielectric fluid negatively affects the accurac...

A wire electrical discharge machined (WEDM) surface is characterized by its roughness and metallographic properties. Surface roughness and white layer thickness (WLT) are the main indicators of quality of a componen...

The paper presents a design of a W-band planar accelerating structure (muffin tin) [1]. The structure is a 2 /3-mode traveling wave, constant impedance structure with an operating frequency of 91.392 GHz. The design includes a new power coupler and a cavity geometry optimized for high shunt impedance. A 7–cell cold test prototype has been fabricated by wire electro discharge machining. Measurem...

There is an increasing demand for industrial products, not only with the increased number of functions and also there will be a requirement of product in reduced size. Hence, it is essential to develop a product with maximum functions and minimum size. Micromachining technology gives the best solution to develop the product with maximum number of functions and also the size of the product will ...

Titanium alloys have found widespread use in aviation, automotive, and marine applications, which makes their implementation mass production more challenging. Conventional methods of removing these alloy materials are unsuitable because the high wear rate cutting slower processing. The complexities prompted creation cutting-edge machining methods. Wire Electrical Discharge Machining (WEDM) is a...
