“…Simulations are performed in two dimensions environment, which can result in discrepancies when machining free-form three dimensional structures. New three dimensional simulation technology like virtual reality (VR) and augmented reality (AR) can provide more accurate results (Mao, Liu, & Gao, 2011). But implementation often requires purchasing costly hardware, computer processing power and training of programmers (Abdul Kadir, Xu, & Hämmerle, 2011).…”

<p>Informed production decision-making requires a structured understanding of the production process and costs associated. This research proposes a decision support system incorporating the learning effects on selecting cost-effective machining production process. The approach is applied to the case on manufacturing wind turbine blades. The machining industry has experienced a surge in demand for complex machining applications and an availability of a wide range of new machining technologies. Producing complex structures requires experienced CNC programmers that perform extensive strategy planning, design and optimization. The system developed considers the production processes, cost items, power learning curve and experience of the programmers. This enables managers to evaluate between various production processes and select the most cost-efficient process. An analytical approach to evaluate cost efficiency between 3-axis CNC and 5-axis CNC machines. The result is a user-friendly planning and selection tool aiding in answering critical managerial questions related to cost-effectiveness.</p><div><br></div>

“…Cycle of part innovations is constantly reduced. These requirements can be effectively achieved only through the use of advanced information CAE (Computer Aided Engineering) technology to help us implement increasingly stringent demands on productivity and quality in the design and production [1,2]. According to the investigation of these authors [4,5,6,7], so-called CAE systems are used for implementation of the requirements in manufacturing practices, which are intended for the development and design of products, graphic modeling, structural analysis of the components, to the programming of production activities CAM (Computer Aided Manufacturing) [8,9] and CNC (Computer Numerical Control) systems.…”

This paper presents the influence of CAD modelling and CAM simulation advanced techniques for hard milling technology. The main aim of simulations is the ability and importance to improve and optimize hard milling process even before the real production of its own products, because their manufacturing process is rather expensive. The reached results present us roughing and finishing process of hard milling and milling strategy or generation of tool-paths in CATIA V5. All simulations of milling experiments show that the proposed clear-up tool path works well in the real cutting process and can improve the machining efficiency of the machining process. At the same time, the manufacturing must have the advanced process equipment and method due to the requirements of the design performance and machining efficiency. Finally, hard milling simulations in CAD/CAM system CATIA V5 were performed in order to determine and evaluation of suitability of the proposed shapes of the hard milling product.

“…This method can also be used in multi-axis machining for the mesh. By using the binary tree and real-time simulation, Mao and Liu et al [12] achieved a three-axis NC milling of the mesh. Huertas-Talón et al [13] used the non-deterministic techniques and spherical tool to obtain a spiral path for machining a mesh surface.…”

Direct mesh machining has been an effective technique in rapid manufacturing. Currently, the cutter location path generation is an effective method for the direct mesh machining. However, this method may cause surface defects, such as the overcut-slot, the transit-pit, and the facet defects. Therefore, the application of this method is limited for the machining accuracy issue. From the comprehensive analysis of cutter location path generation and the inspection of the machined parts by the mesh offset intersection (MOI) algorithm, the tessellation error of the offset mesh is the main factor causing the machining surface defects. To solve the problem, we propose an improved MOI algorithm to reduce the influence of tessellation error. Compared with the original surface, only the mesh vertices are considered as the points without tessellation error. Therefore, we revise the algorithm through calculating the cutter location points only from the vertices and smoothing the tool-path in two perpendicular directions. This improved algorithm includes two sub-algorithms: a vertex-based cutter location point calculation sub-algorithm and a bi-directional spline interpolation sub-algorithm. To validate the effectiveness of the improved algorithm, the machining accuracy is investigated and verified through several testing parts. The experimental results show that the improved MOI algorithm can effectively improve the machining accuracy and avoid surface defects on the work-piece surfaces.
