Product robustness philosophy – a strategy towards zero variation manufacturing (ZVM)

Boorla M. S., Eifler T., McMahon C., Howard T. J.

Management and Production Engineering Review

2018

Vol. 9, No. 2

3--12

A product is referred to as robust when its performance is consistent. In current product robustness paradigms, robustness is the responsibility of engineering design. Drawings and 3D models should be released to manufacturing after applying all the possible robust design principles. But there are no methods referred for manufacturing to carry and improve product robustness after the design freeze. This paper proposes a process of inducing product robustness at all stages of product development from design release to the start of mass production. A manufacturing strategy of absorbing all obvious variations and an approach of turning variations to cancel one another are defined. Verified the application feasibility and established the robustness quantification method at each stage. The theoretical and actual sensitivity of different parameters is identified as indicators. Theoretical and actual performance variation and accuracy of estimation are established as robustness metric. Manufacturing plan alignment to design, complimenting the design and process sensitivities, countering process mean shifts with tool deviations, higher adjustable assembly tools are enablers to achieve product robustness.

Quality engineering implementation in an organization: a brief finding on QE methodology

Dolah R., Miyagi Z., Tatebayashi K.

Management and Production Engineering Review

2012

Vol. 3, No. 4

26-34

As many research focused on robustness methodology, this paper discuss on how to implement these methodology concept from the management perspective. Guidelines and appropriate strategies are discussed on Quality Engineering (QE) implementation in an organization and experimentation. Firstly, the experience of a company implementing QE is presented. Secondly, the practical data of a laboratory experiment is discussed in order to relate between the experimental result and requirement in industry. The QE implementation is explained on the strategies used in tackling organization problems. Optimization of peel adhesion strength test is carried out to propose the feasibility of experimental design tools. QE methodology between the practical case and company's case study is compared. Finally, through the QE implementation in organization and method applied in experimental design, a framework is proposed for QE methodology. QE implementation is presented from two sources, from a company and practical case study point of view. It helps a researcher or engineer applies the management strategy and engineering tool to ensure product robustness.
