... makes it less accurate than subtractive processes. Hence, additive manufacturing techniques could tremendously benefit from finishing processes to improve their geometric tolerance and surface finish. Design/methodology/approach Rotary ultrasonic machining (RUM) was chosen as a finishing operation...

...Giovanni Gómez-Gras; Marco A. Pérez; Jorge Fábregas-Moreno; Guillermo Reyes-Pozo Purpose This paper aims to investigate the quality of printed surfaces and manufacturing tolerances by comparing the cylindrical cavities machined in parts obtained by fused deposition modeling (FDM) with the holes...

... shape components is achieved using 96 per cent Al3O2 ceramic paste extrusion and a planarizing machining operations. Sacrificial polymer support can be used to aid the creation of overhanging or internal features. Post-processing using a variety of machining operations improves tolerances and fidelity...

...Manikandakumar Shunmugavel; Ashwin Polishetty; Moshe Goldberg; Rajkumar Singh; Guy Littlefair Purpose The purpose of this paper is to study and compare the mechanical properties and machinability characteristics of additive manufactured titanium alloy Ti-6Al-4V with conventionally produced wrought...

...Danielle Strong; Issariya Sirichakwal; Guha P. Manogharan; Thomas Wakefield Purpose This paper aims to investigate the extent to which traditional manufacturers are equipped and interested in participating in a hybrid manufacturing system which integrates traditional processes such as machining...

...Jeremy Faludi; Cindy Bayley; Suraj Bhogal; Myles Iribarne Purpose – The purpose of this study is to compare the environmental impacts of two additive manufacturing machines to a traditional computer numerical control (CNC) milling machine to determine which method is the most sustainable...

...Victoria Townsend; Jill Urbanic Purpose The purpose of this paper is to relate additive manufacturing (AM) and machining (CNC) synergistically in a modular approach in the design and manufacturing domains, to generate value for end‐users and manufacturers (a teleological system). Design...

...Brent Stucker; Xiuzhi Qu Rapid prototyping (RP) techniques are being increasingly used to manufacture injection molding and die casting core and cavity sets, known as tools, and for other tooling‐related parts, such as EDM electrodes. This paper presents a STL‐based finish machining technique...

...Y. Tang; J.Y.H. Fuh; L. Lu; Y.S. Wong; H.T. Loh; M. Gupta The feasibility of building copper‐based electrodes for electrical discharge machining (EDM) via laser cladding is investigated as an application of rapid prototyping (RP). Two material systems‐Cu/W (with and without nickel) and Cu...

...Robert E. Williams; Vicki L. Melton This research investigated the use of two relatively new technologies, abrasive flow machining (AFM) and stereolithography (SL), to minimize the time to develop a finished prototype. Statistical analysis was used to determine effects of media grit size, media...

.... This paper presents an open‐loop motion compensation algorithm, which enables the machine tool to move more accurately to a given position and orientation than its physical setup allows. Experimental procedures to measure the geometrical errors in the system setup are also presented in this paper. © MCB UP...
