Abstract

Purpose

While manufacturing organisations were early adopters of ISO 9000, lately, many service sector organisations have also pursued adoption. The aim of this paper is to compare the experiences with the standard of the two sectors.

Design/methodology/approach

The research collected data from 149 service and 160 manufacturing organisations using a common survey measurement instrument.

Findings

Results show that there are no statistically significant differences between the two groups in terms of time and cost of obtaining registration. Also, there are only small points of differences in motivation for registration and difficulties faced. There are greater differences between the groups in terms of benefits gained and management practices associated with the standard.

Originality/value

These results provide interesting insights into how the two groups perceive and engage with the standard, how cross‐industry diffusion could be taking place, and the veracity of the claims made about the universal applicability of the standard. These findings imply that service organisations can learn from the experiences of the manufacturing sector, but copying carte blanche the implementation strategies is fraught with risks. Further, the standard is not universally applicable and may need industry‐specific tailoring.

Abstract

New standards for communications, data exchange, and computer integrated manufacturing systems are being implemented. These new standards and methods of production are not always compatible with existing machines and equipment. Studies show that significant investments would be required to replace the existing machines with new ones complying with the new standards. Describes a case study demonstrating that the implementation of an integrated manufacturing cell using equipment not conforming to high level communications standards is feasible. Also presents a review of computer integrated manufacturing technologies.

Abstract

Purpose

Investing in Industry 4.0 is an important consideration for manufacturing firms who strive to remain competitive in this global economy, but the uncertainty and complexity of where to focus technology investments is a problem facing many manufacturers. The purpose of this paper is to highlight a region of manufacturing firms in the Midwest USA to investigate the role of firm size, access to funds and industry type on decision to invest in and deploy various Industry 4.0 technologies.

Design/methodology/approach

A survey was developed, piloted, and deployed to manufacturing companies located in the Midwest USA, specifically, Indiana, USA. A total of 138 manufacturing firms completed the full survey. The survey participants were requested to rank order the various technology categories with respect to previous historical spending, workforce capabilities and anticipated return on investment. The survey was supplemented with publically available data. Due to the use of rank-order data to identify Industry 4.0 priorities, a non-parametric analysis was completed using the Kruskall Wallis test.

Findings

The findings suggest that manufacturers with less than 20 employees and/or less access to funds (sales less than $10m) prioritize digital factory floor technologies (e.g. technology directly impacting productivity, quality and safety of manufacturing processes). Larger manufacturers with 20 or more employees and/or access to more funds (sales greater than or equal to $10m) prioritize enterprise support operations technologies.

Originality/value

Research studies and reports tend to lump manufacturing’s perspective of Industry 4.0 into one homogenous group, and rarely acknowledge the limited participation of “smaller” Small and medium-sized enterprises, which account for the far majority of manufacturing firms in the USA. The value of this study is on the “novelty of approach,” in that the data collection and analysis focuses on heterogeneity of manufacturing firms with respect to size, access to funds and industry type. The findings and recommendations are beneficial and relevant to organizations supporting Industry 4.0 efforts through workforce development and economic development initiatives.

Abstract

This chapter explores the opportunities and challenges for Western firms that wish to engage in manufacturing operations in Iran, and particularly in the automotive industry. Although Iran has a long and fruitful history of embracing foreign investment, collaboration with foreign firms suffered in the aftermath of the Islamic Revolution in 1979. The imposition of UN sanctions in 2012, following the disagreements between Iran and leading Western powers over Iran’s nuclear policy, has resulted in a further exodus of foreign manufacturers from Iran, hurting the production quality, adoption of up-to-date technology and alignment to international standards for manufacturing, such as vehicle safety and engine emissions in Iran.

The removal of sanctions, contingent on the success of nuclear negotiations between Iran and leading world powers, could provide Iran with an opportunity to recommence manufacturing collaboration with Western firms. The case of the automotive industry discussed in this chapter indicates some of the challenges that Iran is likely to face if it once again wants to become a player in international markets.

Abstract

Purpose

In this era of Fourth Industrial Revolution, also known as Industry 4.0, additive manufacturing (AM) has been recognized as one of the nine technologies of Industry 4.0 that will revolutionize different sectors (such as manufacturing and industrial production). Therefore, this study aims to focus on “Additive Manufacturing Education” and the primary aim of this study is to investigate the impacts of AM technology at selected South African universities and develop a proposed framework for effective AM education using South African universities as the case study.

Design/methodology/approach

Quantitative research approach was used in this study, that is, a survey (questionnaire) was designed specifically to investigate the impacts of the existing AM technology/education and the facilities at the selected South African universities. The survey was distributed to several students (undergraduate and postgraduate) and the academic staffs within the selected universities. The questionnaire contained structured questions based on five factors/variables and followed by two open-ended questions. The data were collected and analyzed using statistical tools and were interpreted accordingly (i.e. both the closed and open-ended questions). The hypotheses were stated, tested and accepted. In conclusion, the framework for AM education at the universities was developed.

Findings

Based on different literature reviewed on “framework for AM technology and education”, there is no specific framework that centers on AM education and this makes it difficult to find an existing framework for AM education to serve as a landscape to determine the new framework for AM education at the universities. Therefore, the results from this study made a significant contribution to the body of knowledge in AM, most especially in the area of education. The significant positive responses from the respondents have shown that the existing AM in-house facilities at the selected South African universities is promoting AM education and research activities. This study also shows that a number of students at the South African universities have access to AM/3D printing lab for design and research purposes. Furthermore, the findings show that the inclusion of AM education in the curriculum of both the science and engineering education is South Africa will bring very positive results. The introduction of a postgraduate degree in AM such as MSc or MEng in AM will greatly benefit the South African universities and different industries because it will increase the number of AM experts and professionals. Through literature review, this study was able to identify five factors (which includes sub-factors) that are suitable for the development of a framework for AM education, and this framework is expected to serve as base-line or building block for other universities globally to build/develop their AM journey.

Research limitations/implications

The survey was distributed to 200 participants and 130 completed questionnaires were returned. The target audience for the survey was mainly university students (both undergraduate and postgraduate) and the academics who have access to AM machines or have used the AM/3D printing lab/facilities on their campuses for both academic and research purposes. Therefore, one of the limitations of the survey is the limited sample size; however, the sample size for this survey is considered suitable for this type of research and would allow generalization of the findings. Nevertheless, future research on this study should use larger sample size for purpose of results generalization. In addition, this study is limited to quantitative research methodology; future study should include qualitative research method. Irrespective of any existing or developed framework, there is always a need to further improve the existing framework, and therefore, the proposed framework for AM education in this study contained only five factors/variables and future should include some other factors (AM commercialization, AM continuous Improvement, etc.) to further enhance the framework.

Practical implications

This study provides the readers and researchers within the STEM education, industry or engineering education/educators to see the importance of the inclusion of AM in the university curriculum for both undergraduate and postgraduate degrees. More so, this study serves as a roadmap for AM initiative at the universities and provides necessary factors to be considered when the universities are considering or embarking on AM education/research journey at their universities. It also serves as a guideline or platform for various investors or individual organization to see the need to invest in AM education.

Originality/value

The contribution of this study towards the existing body of knowledge in AM technology, specifically “AM education research” is in the form of proposed framework for AM education at the universities which would allow the government sectors/industry/department/bodies and key players in AM in South Africa and globally to see the need to invest significantly towards the advancement of AM technology, education and research activities at various universities.

Abstract

Purpose

This paper aims to develop a set of process parameters tailored for lattice structures and test them against standard process (SP) parameters. Selective laser melting (SLM) is a commonly known and established additive manufacturing technique and is a key technology in generating intricately shaped lattice structures. However, SP parameters used in this technology have building time and accuracy disadvantages for structures with a low area-to-perimeter ratio, such as thin struts.

Design/methodology/approach

In this research work, body-centred cubic structure specimens are manufactured using adapted process parameters. Central to the adapted process parameters is the positioning of the laser beam, the scan strategy and the linear energy density. The specimens are analysed with X-ray micro-computed tomography for dimensional accuracy. The final assessment is a comparison between specimens manufactured using adapted process parameters and those using SP parameters.

Findings

Standard parameters for lattice structures lead to a significant shift from the nominal geometry. An extensive manufacturing and computation time due to several exposure patterns (e.g. pre-contours, post-contours) was observed. The tailored process parameters developed had good dimensional accuracy, reproducible results and improved manufacturing performance.

Research limitations/implications

The results are based on a distinctive geometry of the lattice structure and a specific material. Future research should be extended to other geometries and materials.

Practical implications

Optimisation of process parameters for the part geometry is a critical factor in improving dimensional accuracy and performance of SLM processes.

Originality/value

This study demonstrates how application-tailored process parameters can lead to superior performance and improved dimensional accuracy. The results can be transferred to other lattice structure designs and materials.

Abstract

Purpose

The purpose of this study is to explore the applications of 3D printing in space sectors. The authors have highlighted the potential research gap that can be explored in the current field of study. Three-dimensional (3D) printing is an additive manufacturing technique that uses metallic powder, ceramic or polymers to build simple/complex parts. The parts produced possess good strength, low weight and excellent mechanical properties and are cost-effective. Therefore, efforts have been made to make the adoption of 3D printing successful in space so that complex parts can be manufactured in space. This saves a considerable amount of both time and carrying cost. Thereof the challenges and opportunities that the space sector holds for additive manufacturing is worth reviewing to provide a better insight into further developments and prospects for this technology.

Design/methodology/approach

The potentiality of 3D printing for the manufacturing of various components under space conditions has been explained. Here, the authors have reviewed the details of manufactured parts used for zero-gravity missions, subjected to onboard international space station conditions and with those manufactured on earth. Followed by the major opportunities in 3D printing in space which include component repair, material characterization, process improvement and process development along with the new designs. The challenges like space conditions, availability of power in space, the infrastructure requirements and the quality control or testing of the items that are being built in space are explained along with their possible mitigation strategies.

Findings

These components are well comparable with those prepared on earth which enables a massive cost saving. Other than the onboard manufacturing process, numerous other components as well as a complete robot/satellite for outer space applications were manufactured by additive manufacturing. Moreover, these components can be recycled onboard to produce feedstock for the next materials. The parts produced in space are bought back and compared with those built on earth. There is a difference in their nature, i.e. the flight specimen showed a brittle nature, and the ground specimen showed a denser nature.

Originality/value

This review discusses the advancements of 3D printing in space and provides numerous examples of the applications of 3D printing in space and space applications. This paper is solely dedicated to 3D printing in space. It provides a breakthrough in the literature as a limited amount of literature is available on this topic. This paper aims at highlighting all the challenges that additive manufacturing faces in the space sector and also the future opportunities that await development.

Abstract

International competition is driving manufacturing executives to place an ever‐growing importance on the formulation of computer integrated manufacturing (CIM) strategies as part of their corporate plans. Structured analysis and design techniques, in particular IDEF (Integrated Computer Aided Manufacturing definition method), are becoming a vital tool in the analysis and implementation of such CIM strategies. This article positively demonstrates the technique and its ability to model the link between design and manufacture in a CIM environment. The approach relates interdependencies of planning for manufacture, design and process planning within a CIM strategy. In particular it establishes the position of computer aided process planning (CAPP) in CIM architecture and evaluates a CAPP package as a potential element of a CIM strategy. The application to which IDEFo, in particular, has been used clearly demonstrates its usefulness to manufacturers as a powerful aid to the development of detailed CIM strategies.

Abstract

Purpose

The purpose of this research is to study and analyze the literature that integrates Lean Six Sigma (LSS) approach with blockchain technology in different sectors for improved quality management.

Design/methodology/approach

This study presents a scoping review on the application of integrated LSS and blockchain technology in the manufacturing and healthcare sector. Further, the authors examined existing blockchain-based solutions on a variety of dimensions, including application area, technical approach, methodology, application scenario, various blockchain platforms, purpose, and monitoring parameters. The authors study LSS approaches in detail, as well as the key benefits that blockchain technology can enable. Finally, the authors discuss significant research problems to be addressed in order to develop a highly efficient, resilient, and secure quality management framework using blockchain technology.

Findings

It has been observed that the adoption of blockchain technology for quality management and assurance is influenced by several factors such as transaction execution speed, throughput, latency. Also, prior blockchain-based solutions have neglected to leverage the benefits of LSS methodologies for effective quality management.

Originality/value

This is the first study to explores the influence of blockchain technology on quality management and assurance in manufacturing and healthcare industry. Furthermore, prior research has not examined how integrating the LSS methodology with blockchain technology can aid in the control of product quality management.
