PurposeThe purpose of this paper is to explore the researches reported in literature on agile manufacturing (AM) and determine the avenues by which agility can be imparted in traditional sectors.Design/methodology/approachAfter reviewing the literature on AM, it has been found that these papers address AM along as many as 12 directions. The findings of this review are used to design a model called total agile design system (TADS).FindingsThe major finding of the exploration reported in this paper is that, the need of the hour is to sensitize the traditional sectors for acquiring design capabilities compatible for imbibing agility in totality.Research limitations/implicationsThe TADS model proposed has been reviewed only by 25 industry captains. However, this may not affect the credibility of this model as it is designed by referring to a large number of researches reported in peer reviewed articles appeared in leading international journals.Practical implicationsAfter designing, TADS was exposed to 25 industry captains. Their feedback was gathered using a questionnaire. The results of analysis of their feedback indicates the practical compatibility of TADS.Originality/valueIt appears that no researcher has identified the different directions in which AM researches have progressed. Moreover, no researcher has contributed a model to adopt computer aided design (CAD)/computer aided manufacturing (CAM) and rapid prototyping (RP) technologies in totality to achieve agility in manufacturing organisations. As this paper has overcome the absence of these kinds of researches, it is original and valuable.

Practical Implications

Purpose – The main purpose of this paper is to report the successful treatment modality for patients suffering from arthritis of the metatarsophalangeal joint (MTPJ) of the foot which otherwise could not be treated through traditional surgeries. Design/methodology/approach – The unique capabilities of the computer-aided design and the rapid prototyping (RP) technology are used to develop the customized MTPJ implant (SamKu). Findings – This approach shows good results in the fabrication of the MTPJ implant. Postoperatively, the patient experienced normalcy in the movement of the MTPJ of the foot. Practical implications – Advanced technologies made it possible to fabricate the customized MTPJ implant (SamKu). The advantage of this approach is that the physical RP model assisted in designing the final metallic implant. It also helped in the surgical planning and the rehearsals. Originality/value – This case report illustrates the benefits of imaging/computer-aided manufacturing/RP to develop the customized implant and serve those patients who could not be treated in the traditional way. This is a pioneered attempt toward implementation of a customized implant for patients suffering from arthritis of the MTPJ.

Purpose Various occupations in life require personnel to stand for a prolonged period of time. This causes excessive stress on the joints leading to musculoskeletal disorders. This paper aims to design an equipment ensure the personnel rests on whenever necessary. Design/methodology/approach The method followed in this paper is the adoption of Karl Ulrich’s product design methodology with suitable modifications as per requirement. Human anthropometric data from the Indian population has been considered during the design and modelled according to it using computer aided design and computer aided engineering tools. Findings The conceptual equipment – exoskeleton designed sustained loads of human beings and proved to be a safe design in terms of the strength of the material used in the design. Social implications This design can serve as equipment, which helps the personnel with long-standing work hours to relieve themselves without actually sitting. Originality/value The design has been carefully crafted based on the inputs from the anthropometric features of human beings, which is completely passive in nature i.e. no use of external power is required for this exoskeleton compared to the other available designs.

Purpose – The purpose of this paper is to establish an adaptive assembly, to realize the adaptive changing of the models and to improve the flexibility and reliability of assembly change. For a three-dimensional (3D) computer-aided design (CAD) assembly in a changing process, there are two practical problems. One is delivering parameters’ information not smoothly. The other one is to easily destroy an assembly structure. Design/methodology/approach – The paper establishes associated parameters design structure matrix of related parts, and predicts possible propagation paths of the parameters. Based on the predicted path, structured storage is made for the affected parameters, tolerance range and the calculation relations. The study combines structured path information and all constrained assemblies to build the adaptive assembly, proposes an adaptive change algorithm for assembly changing and discusses the extendibility of the adaptive assembly. Findings – The approach would improve the flexibility and reliability of assembly change and be applied to different CAD platform. Practical implications – The examples illustrate the construction and adaptive behavior of the assembly and verify the feasibility and reasonability of the adaptive assembly in practical application. Originality/value – The adaptive assembly model proposed in the paper is an original method to assembly change. And compared with other methods, good results have been obtained.

PurposeThis paper aims to introduce a process chain spanning from scanned data to computer-aided engineering and further required simulations up to the subsequent production. This approach has the potential to reduce production costs and accelerate the procedure.Design/methodology/approachA parametric computer-aided design (CAD) model of the flyer wearing a wingsuit is created enabling easy changes in its posture and the wingsuit geometry. The objective is to track the influence of geometry changes in a timely manner for following simulation scenarios.FindingsAt the final stage, the two-dimensional (2D) pattern cuts were derived from the developed three-dimensional (3D) wingsuit, and the results were compared with the conventional ones used in the first stages of the wingsuit development.Originality/valueProposing a virtual development process chain is challenging; apart from the fact that the CAD construction of a wingsuit flyer – in itself posing a complicated task – is required at a very early stage of the procedure.

Purpose – The purpose of this paper is to use the 5S tool to assist a small-scale manufacturing organization to become more productive and more efficient. Design/methodology/approach – A simple approach has been adopted to create the teams for implementing 5S. Cause-and-effect diagram has been studied for shop floor analysis. Later, four data collection methods have been used to ensure right implementation of the 5S. Findings – In the frames of this case study, it has been analyzed that implementation of “5S” resulted in overall improvement of the organization. With the implementation of “5S”, major benefits in the form of tool searching time have been achieved. Tool searching time from shop floor has been reduced from 30 minutes to 5 minutes. “5S” audit has been conducted in the organization. “5S” audit score has been increased from 7 (Week 1) to 55 (Week 20). Practical implications – 5S is a powerful tool and can be implemented in various industries whether micro, small, medium or large. Implementation of 5S has large horizontal development and can be implemented in all the workstations of an organization. Originality/value – The publications and case study presented in this paper will be useful to researchers, professionals and others concerned with this subject to understand the significance of 5S.
