II Abstract Parker Hannifin QCDE aim to eliminate as much wasted time, materials and resources as achievable by implementing Design for Manufacturing and Assembly principles into a modified version of their Product Development Process. The modified Product Development Process was developed within this project with the objective of aiding the company to remain competitive within their field, as well as continue to efficiently develop and produce high quality products. A literature study was performed to gain a greater understanding of the multiple Design for Excellence methods and their possibilities to enhance the Product Development Process at Parker Hannifin QCDE. The literature study included various sources such as academic books and scientific articles. An empirical study was conducted and the use of the current Internal Product Development Process was evaluated in conjunction with a detailed evaluation of the designated coupling. An additional aspect that was explored includes an evaluation of the extent of Design for Manufacturing and Assembly that is implemented into the current Internal Product Development Process. The Generation chapter of this thesis outlines the sequence and process implemented for generating the modified Internal Product Development Process and implementing Design for Manufacturing and Assembly. The results of this thesis project included implementing Design for Manufacturing and Assembly in the form of checklists. The multiple Design for Excellence checklists were inspired in part by the information obtained from the literature study and the authors interpretation. The finished concept has been provided to Parker Hannifin QCDE in the form of a pamphlet including instructions of how to implement the checklists into the modified Internal Product development process. The discussion chapter within this report consists of a conclusion and deliberation regarding the methodology used within this thesis. The results obtained from this thesis have been dissected and evaluated along with implications and potential weaknesses in the work.

CROSS-FUNCTIONAL TEAM EVALUATION OF THE DFA CHECKLIST 63 7.8 CASE STUDY 63 8 SUGGESTIONS FOR FURTHER INVESTIGATION 64 VI 1 Introduction Parker Hannifin QCDE, Quick Coupling Division Europe, in Skövde primary focus is providing customers with high quality and reliable couplings for use in Climate Control, Construction, Forestry & Mining, Factory Automation, Food & Beverage, Industrial Manufacturing, Industrial Processing & Refining, Life Sciences & Healthcare, Off-Road Transportation, On Road, Rail & Marine Transportation and Power Generation, In order to remain competitive within their field, Parker Hannifin QCDE, henceforth Parker, seeks to improve their current Internal Product Development Process, henceforth PDP, with the help of DFMA, Design for Manufacturing and Assembly, in focus. Currently Parker’s product development primarily consists of modifying existing products to suit their client’s needs. These products are developed foremost with experience within the Parker personnel (internal expertise and judgement) of the company rather than following the steps within the PDPs. 1.1 Problem description The Internal PDP at Parker aligns with the larger PDP internationally used at all Parker locations, called Winovation, yet it is significantly reduced according to the number of steps, resources and time needed. Currently minimal documentation is performed regarding the amount of work applied and performed within the Internal PDP. Due to the lack of documentation, it is difficult for personnel as well as departments within Parker to advocate and confirm their work. The staff rarely executes the existing Internal PDP. This is due to the extent of time needed to perform the tasks within each section. The absence of a solid and beneficial process weakens the current PDP and can reduce the effectiveness of communication between Parker and their clients. The lack of post-launch communication between Parker and their clients has been highlighted as a major disadvantage and in need of immediate attention. 1.2 Aim and Objectives Parker aims to eliminate as much wasted time, materials and resources as possible within their current Internal PDP with the help of DFMA. The main objective of this project is to improve and simplify the Internal PDP at Parker for the company to remain competitive within their field, as well as continue to efficiently develop and produce high quality products. The foundations of the modified Internal PDP will be based on DFMA as requested by the company. To demonstrate that the modified Internal PDP is successful, an existing coupling provided by the company will be analyzed according to the new framework established.

DFA är en metod som handlar om att designa en produkt så att dess egenskaper kommer att ha en inverkan på monteringsvänligheten av produkten. Det främsta målet med DFA är att reducera antalet ingående detaljer i en produkt. Atlas Copco Tools är ett företag som har påbörjat sin resa mot ständiga förbättringar och fokuserat sig bland annat på att förbättra produktutvecklingsprocessen. Därav har företaget visat ett stort intresse för DFA-metoden som ett arbetssätt inom konstruktionsavdelningen. Idag använder sig inte Atlas Copco Tools av en specifik metod som stödjer DFA-metodiken vid utveckling av deras produkter. Den stora frågan i detta examensarbete är därför huruvida DFA lönar sig att implementeras på Atlas Copco Tools i deras produktutecklingsprocess och i så fall hur arbetet med DFA ska ske samt vilka tillvägagångssätt ska användas.

    DEGREE PROJECT IN MECHANICAL ENGINEERING, SECOND CYCLE, 30 CREDITS STOCKHOLM, SWEDEN 2018 Implementing Design For Automatic Assembly A recommendation on how to implement and apply DFAA at Company Y FILIPPA VON YXKULL KTH ROYAL INSTITUTE OF TECHNOLOGY SCHOOL OF INDUSTRIAL ENGINEERING AND MANAGEMENT Implementing Design For Automatic Assembly A recommendation on how to implement and apply DFAA at Company Y Filippa von Yxkull Master of Science Thesis TPRMM: 2018: KTH Production Engineering and Management Industrial Production SE-100 44 STOCKHOLM Abstract The need to work with Design for Automatic Assembly (DFAA) has been widely recognized in the literature. However, the implementation of DFAA is not clearly defined. Therefore, the purpose of this master thesis is to investigate and contribute with knowledge of how DFAA should be implemented into an organization, such as Company Y. Several interviews have been conducted to establish a current state analysis, to receive an understanding of the current problems at Company Y and how to address them. A benchmarking study was conducted, where the three companies Ericsson, Company X and Scania were interviewed. All three companies have successfully implemented DFA and were interviewed with the purpose to obtaining their best practices. The study also included an early implementation of DFAA, where a software based DFA2-method created by Eskilander (2001) was tested on a current product and a new developed design concept at Company Y. Based on this a recommended workflow of the evaluation could be attained. Based on the empirical gatherings several recommendations of how DFAA should be implemented into the organization could be made.

  • A Cost-Effective Knowledge-Based Reasoning System for Design for Automation
    1 A cost-effective knowledge-based reasoning system for design for automation E M Shehab1* and H S Abdalla2 1Department of Manufacturing, Cranfield University, Cranfield, UK 2Department of Product and Spatial Design, De Montfort University, Leicester, UK The manuscript was received on 3 February 2005 and was accepted after revision for publication on 16 December 2005. DOI: 10.1243/095440554JEM298 Abstract: Design for assembly automation (DFAA) is an important part of the concurrent engineering strategy for reduction of product manufacturing costs and lead times. An intelligent knowledge-based system (KBS) for design for automation and early cost modelling within a concurrent engineering environment has been developed. This paper focuses upon the development of the design for an assembly automation system. The system framework encompasses an extensive knowledge base reasoning system, a CAD system, a design analysis for automation module, a design improvement suggestion module, and a user interface. The development process of the system involved three main stages: creating the KBS, developing the design improvement module, and integrating the KBS with the CAD system. The developed system has the capability to: (a) select the most economic assembly technique for the product at an early design stage; (b) estimate the assembly time and cost for manual, automatic, and robotic assembly methods; and (c) analyse the product design for automation and provide the designers with design improvement suggestions of a product to simplify assembly operations without any compromise of the product functionality. The above capabilities of the system have been demonstrated and validated through a real case study. Keywords: design for automation, concurrent engineering, knowledge-based systems, assembly cost estimation 1 INTRODUCTION good design from the assembly point of view [7].

  • Genetic Algorithm Optimization of Product Design for Environmental Impact Reduction
    GENETIC ALGORITHM OPTIMIZATION OF PRODUCT DESIGN FOR ENVIRONMENTAL IMPACT REDUCTION JULIROSE GONZALES THESIS SUBMITTED IN FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY FACULTY OF ENGINEERING UNIVERSITY OF MALAYA KUALA LUMPUR 2018 ABSTRACT The growing environmental awareness of today’s consumers has put the manufacturing companies with the burden of taking responsibility for their own product’s environmental impact. This incited the need to develop product management systems which focus on minimizing a product’s impact across its life cycle. However, a survey conducted on Malaysian design companies suggests that there are no systems available for them to include environmental considerations in their product design processes. This dissertation presents a study on product design optimization which focuses on the inclusion of the potential environmental impact in the design consideration. The aim of this research is to develop a methodology that will aid designers to reduce the potential environmental impact of a product’s design, which does not require them to train additional skills in environmental impact analysis. Analysis of the effect of changing the product design parameters such as its dimensions, and basic features on the environmental impact of machining process in terms of its power consumption, waste produced and the chemicals and other consumables used up during the process is the key method in this research. A novel feature-based product design methodology based on an integrated CAD-LCA approach is developed which analyzes a product design’s environmental impact. Genetic Algorithm is applied to the product design parameters to create a feedback system in order to get the best possible product design solutions with the least environmental impact within the product design functionality limitation.

The final version is available online: http://www.tandfonline.com/10.1080/17452007.2020.1768505 5 6 Abstract 7 Design for manufacture and assembly (DfMA) has become a buzzword amid the global 8 resurgence of prefabrication and construction industrialization. Some argued that DfMA is 9 hardly new, as there are concepts such as buildability, lean construction, value management, 10 and integrated project delivery in place already. Others believe that DfMA is a new direction 11 to future construction. This paper aims to review the development of DfMA in manufacturing 12 and its status quo in construction, and clarify its similarities and differences to other concepts. 13 A multi-step research method is adopted in this study: First, an analytical framework is 14 generated; Secondly, a literature review is conducted on DfMA in general, and DfMA-like 15 concepts in the AEC industry; The third step is to compare DfMA with related concepts. This 16 study reveals that DfMA as a philosophy is hardly new in construction, and the empirical 17 implementation of many DfMA guidelines has begun in the AEC industry.
