“…Such recast formation of the molten layer can subsequently fulfill some spark-induced cavities and other uneven features, thus decreasing the overall surface roughness. This explanation is also noted by Wang et al [53] and Punturat et al [54]. During Wire-EDM, high temperature of the parking zone (A, B, C) and sub-zones (A1, A2, A3, A4), (B1, B2, B3, B4) and (C1, C2, C3, C4) causes the target materials (carbon steel 1017, Fe = 98.4%) to melt during pulse-on time.…”

Electrical discharge machining is an old technology that has been used for old manufacturing processes. Nowadays, the modernized version of the machine is used to manufacture different objects using a wire feed. The parameters in which the machine operates have diverse effects on product quality and surface finish. This paper investigates the performance of a wire electrical discharge machining process for different wire feed rates. The process is a non-traditional machining method. Several tests have been performed considering a carbon steel 1017 and aluminum alloy 6060 machined via Wire-EDM. By using different wire feed rates (3 mm/min, 5 mm/min and 7 mm/min), the average surface roughness, R a , has been investigated in this study. Results show that the wire feed rate is a significant variable to the surface quality finish. The surface roughness of the test target materials increased as this variable increased. The present study recommends setting the wire feed rate as low as possible with the aim of improving results in the surface quality finish. The obtained results and some of the most necessary parameters affecting the manufacturing process of wire-EDM are briefly defined and are then discussed in detail in this study.

“…Nanjing University of Aeronautics and Astronautics used electric discharge and anodic etching together in a high speed wire electrical discharge machining (HSWEDM) machine and reported an increase of 200-600% in the cutting rate. 43 Using this system, 5-µm-long wedgetype micro-grooves and square-type micro-structures were fabricated for use as micro-molds. By combining micro-EDM and high-frequency dither grinding, it is possible to improve the precision by 40%.…”

In this paper, a total of 57 micro and nano scale hybrid manufacturing processes are reviewed. These processes are categorized in terms of process timing and process type. Process timing is one of the most important aspects of manufacturing, and three different process schemes -concurrent, main/assistive (M/S) separate, and main/main (M/M) separate -are considered. The process type is categorized as either geometrically additive or subtractive, and all hybrid processes are categorized into combinations of additive, subtractive, and assistive process. Features and advantages are described for each of these classifications. Machining is found to be the most common process for both micro and nano-scale hybrid manufacturing. Of micro scale hybrid manufacturing schemes, 74.4% use assistive processes as a secondary process because the main purpose of most micro scale hybrid manufacturing is to improve the quality of the process. In nano scale manufacturing, 61.5% of hybrid manufacturing schemes employ assistive processes, since these processes typically focus on the fabrication of parts that are difficult to fabricate using a single, existing process. Based on a summary of published work, future trends in hybrid manufacturing at the micro and nano scale are suggested.

Today, hybrid manufacturing technology has drawn significant interests from both academia and industry due to the capability to make products in a more efficient and productive way. Although there is no specific consensus on the definition of the term 'hybrid processes', researchers have explored a number of approaches to combine different manufacturing processes with the similar objectives of improving surface integrity, increasing material removal rate, reducing tool wear, reducing production time and extending application areas. Thus, hybrid processes open up new opportunities and applications for manufacturing various components which are not able to be produced economically by processes on their own. This review paper starts with the classification of current manufacturing processes based on processes being defined as additive, subtractive, transformative, joining and dividing. Definitions of hybrid processes from other researchers in the literature are then introduced. The major part of this paper reviews existing hybrid processes reported over the past two decades. Finally, this paper attempts to propose possible definitions of hybrid processes along with the authors' classification, followed by discussion of their developments, limitations and future research needs.
