This article proposes a novel approach to generate patterned indentations for different additive manufacturing methodologies. Surface textures have many practical applications in various fields, but require special manufacturing considerations. In addition to conventional manufacturing processes, additive processes have also been utilized in the last decade to obtain textured surfaces. The current design and fabrication pipeline of additive manufacturing operations have many disadvantages in that respect. For instance, the size of the design (CAD) files grows considerably when there are detailed indentations on the surfaces of the artifacts. The presented method, which employs morphological operations on a sequence of binary images representing the cross-sections of the printed artefact, overcomes such problems while fabricating the textured objects. Furthermore, the presented technique could be conveniently implemented using the existing hardware resources of almost any three-dimensional printer.

Analysis of a deterministic demand production/inventory system under nonstationary supply uncertainty
Gullu, R; Onol, E; Erkip, N (Informa UK Limited, 1997-08-01)
In this article we investigate a periodic review inventory model under deterministic dynamic demand and supply unavailability. In a given period, supply is either available or completely unavailable with given probabilities. Supply unavailability probabilities are nonstationary over time. We show the optimality of an order-up-to level policy, and obtain a newsboy-like formula that determines the optimal order-up-to levels. Our formula would provide guidence as to the appropriate amount of inventory to stock...
Designing energy-efficient high-precision multi-pass turning processes via robust optimization and artificial intelligence
Khalilpourazari, Soheyl; Khalilpourazary, Saman; ÇİFTÇİOĞLU, AYBİKE ÖZYÜKSEL; Weber, Gerhard Wilhelm (Springer Science and Business Media LLC, 2020-09-01)
This paper suggests a novel robust formulation designed for optimizing the parameters of the turning process in an uncertain environment for the first time. The aim is to achieve the lowest energy consumption and highest precision. With this aim, the current paper considers uncertain parameters, objective functions, and constraints in the offered mathematical model. We proposed several uncertain models and validated the results in real-world case studies. In addition, several artificial intelligence-based s...

Free forming of locally heated specimens
Okman, O.; Ozmen, M.; Huwiler, H.; Tekkaya, A. E. (Elsevier BV, 2007-06-01)
A novel manufacturing method is investigated, in which a steep temperature gradient within the workpiece is induced to facilitate material flow locally. By this method, complex shapes can be formed without complicated dies. The feasibility of the idea is analyzed experimentally and numerically. Local heating is realized either by means of induction or laser heating. Experiments using materials 16MnCr5, X5CrNi18/9, and Ti6Al4V have been conducted under various process conditions. These experiments have also ...
Proposal and evaluation of a KBE-RM selection system
Munguia, Javier; Bernard, Alain; Erdal Erdoğmuş, Merve (Emerald, 2011-01-01)
Purpose - The purpose of this paper is to propose and evaluate a novel tool for the assessment and selection of rapid prototyping (RP)/manufacturing (RM) systems as alternative processes for low-volume production in the machinery and equipment design sector. By analysing previous RP/RM selectors, this research addresses the necessary factors that a knowledge-based engineering (KBE) system must include for the analysis, comparison and ranking of candidate technologies.
