AbstractAn approach for overcoming negative influences of scaling effects in micro production is the manufacturing of micro parts in a linkage. Due to the linkage a process reliable handling is enabled and chaining of the single process steps for manufacturing becomes easier. The consideration of the technological view in development projects is often insufficient. For reliable production process, data structures have to be defined and filed. ISO 10303 STEP constitutes an approach to save required data. The suitability of STEP for micro formed products by means of the line type linkage and possibilities for integration of this discipline into STEP are discussed.
