“…Furthermore, CAD models with appropriate prototyping technology support not only evaluation of the JEDT 21,5 part design for early detection and reduction of design errors but also to provide a route for significant economic benefit through the enhanced conceptualization of part designs to reduce product development costs, as well as to improve part quality (Blindheim et al, 2020;Guangchun et al, 2004;Ferreira, 2006). Further, the FP approach was introduced to produce physical samples and functional parts in a short turnaround time explored the feasibility of introducing agility in manufacturing by the quick development of the reconstructed CAD models (Ali et al, 2013;Ali and Chowdary, 2011;Vinodh et al, 2009aVinodh et al, , 2009b. 3D printers can also be used to build the prototypes of the generated CAD models.…”

“…Some benefits of CNC machining include the ability to complete complex work pieces, increased part accuracies, tighter tolerances and significant savings in setup time (Djassemi, 2009). Various applications of the CNC machining process to achieve rapid part development have been observed adequately in the literature Chang et al (2006), Bagci (2009), Vinodh et al (2009a), Chowdary (2011), Al-wswasi andIvanov (2019) and some of these studies are presented below. Chang et al (2006) incorporated CNC machining simulations as part of the FP process to produce physical samples and functional replacement parts for aging systems in a short turnaround time.…”

“…In addition, an iso-phote method was used for surface continuity analysis of the developed CAD models which were subsequently transferred into a CAM module for manufacture by means of a CNC milling machine. Vinodh et al (2009a) carried a study to prove the effectiveness of interfacing CAD/CAM systems in a local manufacturing firm with the aim of obtaining agile characteristics.…”

“…Due to intensive global competition, upgrade of the traditional product development process has become the main focus of the contemporary manufacturing industry. To meet the situation, product development tools such as computer aided design (CAD) and computer aided manufacturing (CAM) have been implemented successfully (Vinodh et al, 2009a(Vinodh et al, , 2009bChowdary and Kanchan, 2013;Gokool et al, 2015;James et al, 2017;Das et al, 2018;Helle and Lemu, 2021). Among many engineering problems encountered by the product design and development practitioners, the problem of time compression with a high-quality design, is the most technically challenging task.…”

Purpose This paper aims to present a reverse engineering (RE) approach for three-dimensional (3D) model reconstruction and fast prototyping (FP) of broken chess pieces. Design/methodology/approach A case study involving a broken chess piece was selected to demonstrate the effectiveness of the proposed unconventional RE approach. Initially, a laser 3D scanner was used to acquire a (non-uniform rational B-spline) surface model of the object, which was then processed to develop a parametric computer aided design (CAD) model combined with geometric design and tolerancing (GD&T) technique for evaluation and then for FP of the part using a computer numerical controlled (CNC) machine. Findings The effectiveness of the proposed approach for reconstruction and FP of rotational parts was ascertained through a sample part. The study demonstrates non-contact data acquisition technologies such as 3D laser scanners together with RE systems can support to capture the entire part geometry that was broken/worn and developed quickly through the application of computer aided manufacturing principles and a CNC machine. The results indicate that design communication, customer involvement and FP can be efficiently accomplished by means of an integrated RE workflow combined with rapid product development tools and techniques. Originality/value This research established a RE approach for the acquisition of broken/worn part data and the development of parametric CAD models. Then, the developed 3D CAD model was inspected for accuracy by means of the GD&T approach and rapidly developed using a CNC machine. Further, the proposed RE led FP approach can provide solutions to similar industrial situations wherein agility in the product design and development process is necessary to produce physical samples and functional replacement parts for aging systems in a short turnaround time.

A reliable system means being able to perform its intended functions. Therefore, ensuring performing of its required functions will help to enhance its reliability. For a manufacturing system (e.g. computer numerical control machines), there are a large number of functions, which complicate and make analysis difficult. In this article, a logical and systems approach of graph theory, which is effective to eliminate such difficulties, is employed. The graph theoretic models do consider the system structure explicitly and are applied to model functions at various hierarchical levels of a manufacturing system. These function digraph models are analysed using matrix approach to examine the cause and effect, which helps to evaluate importance of the function and hence provide direction for system reliability enhancement. A step-by-step methodology is presented, which is illustrated by an example of manufacturing system: computer numerical control drilling machine.
