| 4 Micromachining In recent years, micromachining requirements have been significantly increased, primarily due to the need for the use of microcomponents in microelectronics, optical biomedical, automotive aerospace, and many other fields [14] . These microcomponents have geometric properties from a few microns to a millimeter TABLE 11.1 Measurable sustainability factors in machining processes and their desired levels. Measurement factor Desired level Energy consumption Minimum Production costs Maximum Environmental impact Minimum Operational security Maximum Personal health Maximum Waste management Maximum 290 High speed machining and consist of various engineering materials, for example, titanium alloy, aluminum alloy, stainless steel, ceramics, copper, and polymers [15,16] . Among the few microfabrication methods to produce the microcomponents in question, micromilling takes place among the promising mechanical microfabrica- tion methods. Furthermore, in comparison with other microproduction methods, including lithography, laser processing, and ion beam processing, there are many advantages such as the production of a complex three-dimensional shape, shorter processing time, high precision, and broad applicability to different materials The issue of microcutting has been explored since the sand in the sit focused exclusively on micromilling of dies and molding Fig. 11.3 shows the distribution of the number of published studies in the last 10 years related to micromilling. As a result of this survey, it is observed that interest in micromilling has doubled recently compared to 10 years ago and it is still an attractive subject for researchers. This issue has been examined with different perspectives, especially in Asia (Japan, China, Singapore, Malaysia, Indonesia, India, and South Korea, Europe (Italy, Germany, Spain, Denmark, and the United Kingdom, and North America (Canada and the United States). The main issues that should be considered in micromilling, work material, tool, and machine tool requirements are emphasized, and Fig. 11.4 presents the main aspects of micromilling. Fig. 11.4 presents the distribution of the material types utilized in micro- machining studies. The majority of these studies, including low hardness carbon steels, aluminum, and copper alloys, are considered to be of interest to the workpiece materials that are thought to be easy to cut. Low-hardness steels include nonhardened carbon steels, high-strength low-alloy steels, and high- alloy steels. Others include heat-resistant alloys, unbonded WC and WCu alloy. Download 0.88 Mb.
