Robust design and geometry assurance considering assembly ergonomics

Paper in proceeding, 2012

The objective of this study was to explore how assembly ergonomics issues were regarded by geometry engineers. Therefore, 21 geometry engineers in two manufacturing companies were interviewed. Their answers show good awareness of the implications of poor assembly ergonomics but appropriate working procedures and support in CAT (Computer Aided Tolerancing) tool are missing. 95% of the respondents would like to add consideration to assembly ergonomics in their CAT simulation. Based on this study a number of assembly factors that need to be included and considered in locating scheme definition and geometric stability analysis are identified and presented. Altogether, the results show a need for organizational change and CAT tool development.
