... of properties with fewer defects, such as the traditional casting process facilitates polycrystalline formation, which has grain boundaries that lead to creep failure. Besides, it has a high hardness and strength, making it very difficult to machine. A few studies only have discussed the conventional machining...

...Ergun Ateş; Kadir Aztekin Machining values used in this experiment are provided in Table 1 . Diameter of AISI 1050 work piece was reduced to 49 mm from 50 mm by turning its outer surface prior to the experiment. A cutting tool with width of 5 mm was used on the work piece with diameter of 49...

... of metals. Specifically, sets of channels were fabricated using micromilling on 304 stainless steel and 101 copper under varying machining conditions with and without scCO 2 MWF. Burr formation, average specific cutting energy, surface roughness, and tool wear were analyzed and compared. Compared to dry...

...Ahmet Akdemir; Şakir Yazman; Hacı Saglam; Mesut Uyaner Ductile iron can acquire enhanced thermal and mechanical properties from austempering heat treatment. The present study aims to identify the function of different cutting parameters affecting machinability and to quantify its effects. Turning...

...J. Samuel; A. Dikshit; R. E. DeVor; S. G. Kapoor; K. J. Hsia The machinability of carbon nanotube (CNT)-reinforced polymer composites is studied as a function of CNT loading, in light of the trends seen in their material properties. To this end, the thermomechanical properties of the CNT composites...

...K. Aslantas; İ. Ucun; K. Gök The study deals with the machinability properties of austempered ductile iron using cubic boron nitride cutting tools. To emphasize the role of the austempering process, ductile iron specimens were first austenitized in salt bath at 900 ° C for 60 min , after which...

...Gérard Poulachon; Alphonse L. Moisan; I. S. Jawahir Modeling of machining operations requires the use of constitutive relations which could represent as close as possible the material behavior in the primary and secondary zones. The knowledge of these behavior laws involves the use of different...

...S. Kannan; H. A. Kishawy; M. Balazinski The machining of composites present a significant challenge to the industry. The abrasive reinforcements cause rapid tool wear and increases the machining cost. The results from machining metal matrix composites (MMCs) with conventional tools show...

...J. Samuel; R. E. DeVor; S. G. Kapoor; K. J. Hsia The machinability of a polycarbonate nanocomposite containing multiwalled carbon nanotubes is investigated and contrasted with its base polymer and with a conventional carbon fiber composite. The material microstructures are characterized using...

...Ye Li; Matthew C. Frank This paper presents a method for geometric machinability analysis. The implementation of the strategy determines the machinability of a part being processed using a plurality of 3-axis machining operations about a single axis of rotation for setup orientations.
