Optimizing multiple process parameters in fused deposition modeling with particle swarm optimization
Springer Science and Business Media LLC - Tập 14 - Trang 393-405 - 2019
Fused deposition modeling (FDM) is one of the most widely used additive manufacturing processes to produce prototypes as well as functional parts from thermoplastics. However, the applications of the FDM process are still limited due to several drawbacks, such as poor surface quality, poor mechanical properties, or high built time. It has been deemed that the part characteristics and build time ca......
Methods for designing assistive devices extracted from 16 case studies in the literature
Springer Science and Business Media LLC - Tập 6 - Trang 93-100 - 2012
This paper studies existing design methods for designing assistive devices. Publications discussing how to select a design method when designing for disabled people are rare. However, designers do design for disabled people and researchers do publish these case-studies. The aim of this paper is to extract the underlying design methods from design cases. Sixteen case-studies presenting the design o......
Effect of different tool pin geometries on force, torque, microstructure and mechanical properties of friction stir welded acrylonitrile butadiene styrene and polycarbonate joints
Springer Science and Business Media LLC - - Trang 1-12 - 2024
In this research, the effect of tool pin geometry on the development of heat, torque and force during friction stir welding of acrylonitrile butadiene styrene (ABS) and polycarbonate (PC) plate by using double shoulder tool was examined. The overarching aim is to investigate a suitable tool pin geometry that can provide a considerable amount of weld properties. The experiments were conducted with ......
Modeling and optimization of WEDM machining of armour steel using modified crow search algorithm approach
Springer Science and Business Media LLC - - Trang 1-21 - 2024
Armour steel is a type of steel that is often used in armoured vehicles, military equipment, and structural components that require a high level of resistance to penetration. Because of its high strength and hardness, cutting armour steel presents various obstacles. To overcome these challenges in armour steel cutting, innovative cutting methods, specialized equipment, and careful process planning......
Fabrication and analysis of ABS-HDPE-PC composite polymer filament used for FDM printing using hybrid algorithm
Springer Science and Business Media LLC - Tập 17 - Trang 3199-3209 - 2023
The proposed work presents a novel composite polymer filament made by blending High-Density Polyethylene (HDPE) and Polycarbonate (PC) with Acrylonitrile Butadiene Styrene (ABS), resulting in improved properties such as strength-to-weight ratio and impact resistance, expanding the applicability of ABS in healthcare, automotive, and engineering industries. The composite polymer filament was fabrica......
Investigation on the effect of laser parameters and hatch patterns on the dimensional accuracy of micro-dimple and micro-channel texture geometries
Springer Science and Business Media LLC - - Trang 1-18 - 2023
This study investigates the design, simulation and fabrication of micro-dimple and micro-channel texture geometries and the effect of laser parameters and hatch patterns on its dimensional accuracy on carbide tools. Micro-textures were fabricated using a 30-Watt pulsed 1068 ns infra-red fiber laser. The intended design width/diameter and pitch for micro-channels and micro-dimples were 80 and 190 µ......
A multi-disciplinary distributed simulation environment for mechatronic system design enabling hardware-in-the-loop simulation based on HLA
Springer Science and Business Media LLC - Tập 1 - Trang 175-179 - 2007
This paper proposes a high-level architecture-based multi-disciplinary distributed simulation environment for designing mechatronic systems. In the system, commercial off-the-shelf simulators can communicate each other via real-time-infrastructure to realize software-in-the-loop simulation. Moreover, hardware prototypes can also participate in a part of the distributed simulation environment which......
Design and modeling to identify a defective workpiece in manufacturing process: an industry 4.0 perspective
Springer Science and Business Media LLC - - Trang 1-17 - 2023
Traditionally, the sampling process is done manually by verifying a handful of objects from a batch of several objects being produced. Based on the quality of the handful of objects verified, the whole batch may be accepted or rejected. Mistakes during manual sampling process may cause a number of defected objects to be accepted and a number of fine objects to be rejected which in turn may increas......
Content-based 3D mesh model retrieval from hand-written sketch
Springer Science and Business Media LLC - Tập 2 - Trang 87-98 - 2008
Recently, huge numbers of 3D models (solid, surface, and mesh models) have been archived in CA-X systems for industrial design, engineering, manufacturing and e-commerce. Efficient searching methods for 3D models become important for system users. For this purpose, a content-based 3D mesh model retrieval system from hand- written sketch is proposed in this paper. In the system, the user puts a que......
