Product design is significantly dependent on its manufacturing processes. Machining, which is one of the subtractive processes, has a number of limitations related to the complexity of the product geometry [1]. Design of most products, which are to be produced by machining, is adapted to the technology itself [2].In the last decade, techniques that combine two or more manufacturing processes, such as subtractive and additive technologies, are gaining significant attention. This has resulted in many researches on the combination of subtractive and additive technologies. As a contribution to the field, in this paper an algorithm, which was developed for the purpose of being used with a hybrid manufacturing cell, is presented. The hybrid manufacturing cell was developed at institute SINTEF [3] to [5], where two manufacturing machines have been used/combined. The first machine is a Deckel-Maho 5-axis CNC milling center and the other is ConceptLaser M2 for selective laser melting of metal powders. The aim of the hybrid manufacturing cell is to automate the hybrid manufacturing process as much as possible, for the production of different products. The developed algorithm presented in this paper is a significant part of this automation chain. The desired operation of the control system in the hybrid manufacturing cell is to analyze the intended product CAD model with the mentioned algorithm and determine which parts are c be manufactured by the additive and which by the subtractive process.The first attempt to combine benefits of additive and subtractive manufacturing was the low cost integration of an arc welding unit on a 3-axis CNC milling center, presented in [6] and [7]. The main purpose of this research was to manufacture the near-net shape of the product by weld-deposition of material directly on the CNC machine table and then improve the quality of the product surface by milling. The idea is good, however, due to the rough nature of the welding process, the researched process demonstrates limited benefits of other additive manufacturing processes.Several researchers have published work on the methodology for the evaluation of manufacturing complexity for both additive and machining manufacturing [8]

Surface texture formation in precision machining of direct laser deposited tungsten carbide

et al. 2017

This paper focuses on an analysis of the surface texture formed during precision machining of tungsten carbide. The work material was fabricated using direct laser deposition (DLD) technology. The experiment included precision milling of tungsten carbide samples with a monolithic torus cubic boron nitride tool and grinding with diamond and alumina cup wheels. An optical surface profiler was applied to the measurements of surface textures and roughness profiles. In addition, the micro-geometry of the milling cutter was measured with the application of an optical device. The surface roughness height was also estimated with the application of a model, which included kinematic-geometric parameters and minimum uncut chip thickness. The research revealed the occurrence of micro-grooves on the machined surface. The surface roughness height calculated on the basis of the traditional kinematic-geometric model was incompatible with the measurements. However, better agreement between the theoretical and experimental values was observed for the minimum uncut chip thickness model.
