This paper presents a new command generation technique titled VEPRO for computer controlled production machinery. In this method, the tool trajectory is described by a high-level scripting language that enables parametric representations of complex work-piece geometries. The interpreted script is then employed to generate the interpolation data required to compute a tool trajectory that is subjected to a number of kinematic constraints. A real-time interpolator is employed to provide the position commands required by each motion controller in a synchronous fashion. As a proof of concept, the proposed method is emulated on a PC using Python scripting language. The performance of the paradigm is rigorously assessed via two test cases involving different manufacturing techniques (e.g. pocket milling and 3D printing). Through the experimental results, the paper illustrates that the technique, which lends itself for real-time hardware implementation, exhibits satisfactory performance for all intensive purposes and that the method is technically feasible for a wide spectrum of manufacturing applications and systems.

An intelligent process planning system for prismatic parts using STEP features Amaitik, Saleh M.; Kilic, S. Engin (Springer Science and Business Media LLC, 2007-01-01) This paper presents an intelligent process planning system using STEP features (ST-FeatCAPP) for prismatic parts. The system maps a STEP AP224 XML data file, without using a complex feature recognition process, and produces the corresponding machining operations to generate the process plan and corresponding STEP-NC in XML format. It carries out several stages of process planning such as operations selection, tool selection, machining parameters determination, machine tools selection and setup planning. A h...
Investigating the formation of intermetallic compounds during friction stir welding of magnesium alloy to aluminum alloy in air and under liquid nitrogen Mofid, M. A.; Abdollah-zadeh, A.; Gür, Cemil Hakan (Springer Science and Business Media LLC, 2014-03-01) This research demonstrates the use of submerged friction stir welding under liquid nitrogen as an alternative and improved method for creating fine-grained welds, and hence, to alleviate formation of intermetallic phases. Magnesium alloy and aluminum alloy were joined by friction stir welding in two environments, namely air and liquid nitrogen, with 400 rpm rotation and 50 mm/min travel speed. The temperature profile, microstructure, scanning electron microscope energy dispersive X-ray spectroscopy analysis...
Integrating flexible process plans with scheduling in flexible manufacturing systems Saygin, C; Kilic, SE (Springer Science and Business Media LLC, 1999-01-01) This paper highlights the importance of integration between process planning and scheduling in flexible manufacturing systems (FMS). An effective integration increases the potential for enhanced system performance and enhanced decision making. A framework that integrates flexible process plans with off-line (predictive) scheduling in FMS is presented The flexibility in process planning, including process flexibility, sequence flexibility, and alternative machine tools, is discussed. The proposed framework c...
A fractal conductivity-based approach to mobile sensor networks in a potential field Sedat, Nazlibilek; Aydan, Erkmen (Springer Science and Business Media LLC, 2008-06-01) This paper presents the design of multi-robots or multiple mobile sensors and gives the results of the team behavior of them in a potential field in a collaborative manner. The aim is to prove the concept of the fractal conductivity-based approach to mobile sensor networks in a potential field. We attempted to create multi-robots having similar inherent nature, similar background knowledge, and the same mission as relevant bodies, the creation of some sort of attraction force between them is achieved with t...
A novel neutral point potential stabilization technique using the information of output current polarities and voltage vector Yamanaka, K; Hava, Ahmet Masum; Kirino, H; Tanaka, Y; Koga, N; Kume, T (Institute of Electrical and Electronics Engineers (IEEE), 2002-11-01) This paper proposes a new neutral point potential control technique for the neutral-point-clamped three-level inverter. Utilizing the phase current polarity information, this technique distributes the redundant voltage vectors in a manner to obtain stable neutral point voltage under all operating conditions including the zero-power-factor condition. Detailed analysis and computer simulations show the superiority of the proposed method. The feasibility of the proposed method has been proven via laboratory ex...
