Abstract

For simplified processing, micro parts are handled as linked parts. The length of the frame structure of these linked parts can
change during a multi-stage production process especially when forming is included. Hence, the positions of individual parts are not
constant within the linkage. An individual referencing of the parts becomes necessary in each production step. In this paper, a visual
high-speed on-line part referencing system is presented and analyzed. Especially, the trade-off between the highest possible feed
velocity and the demand of high accuracy in micro production is taken into account. In addition to this general characterization
application related testing with stepwise positioning is performed.

Key words: Multi-stage micro part production, linked parts, visual referencing system
