THE BASIC CONCEPTS OF MICRO-MILLING PROCESS AND ITS REVIEW IN TERMS OF DISTINCTIVE PARAMETERS

Abstract

The micro-milling process is relating to the production of miniature parts, and it isone of the significant micromachining processes. The size of parts produced bymicromachining is smaller than millimeters and in the range of a few microns. In thelast years, the demand for needs to minimal parts in industries, such as biomedical,communication, and aerospace have been increased. To encounter this need, one ofthe proper solutions is the micro-milling process. In this study, a review of themicro-milling process was achieved in terms of the important common terms andsome concepts. Terms like size effect, minimum chip thickness, and ploughingphenomenon were evaluated with respect to literature. These terms can be takeninto account to distinguish a major difference between micro and macro cuttingprocesses. In addition to, surface quality is an important required factor formachined parts. In this work also the surface roughness and burr formationmechanism were showed because they represent an inevitable result in the microcutting process. In addition to the micro-milling process have been assessed interms of important factors used in determining the quality of workpieces such assurface quality, burr formation, and cutting forces. In conclusion, this studyinvestigated the important parameters in the micro-milling process and providedgeneral information to compare the micro-milling with conventional milling.
