4TH INTERNATIONAL DAAAM SYMPOSIUM INDUSTRIAL ENGINEERING − INNOVATION AS COMPETITIVE EDGE SME th 29 − 30 April 2004, Tallinn, Estonia MODIFIED CALCULATION METHOD OF TOLERANCE OF DIMENSIONAL CHAIN DEPENDENT LINK Edi Kulderknup Rein Laaneots Karl Raba edikuld@staff.ttu.ee laaneots@staff.ttu.ee karl.raba@ Tallinn University of Technology Institute of Mechatronics Ehitajate tee 5, 19086 Tallinn, Estonia ABSTRACT and structural change of product details materials. Environment temperature and moisture and pollution have especial influence to Industrial constructions mainly are made up of the several exploitation. components which material has different physical properties. In this study work currently are under observation in dependent Parameters of the details and the assemblies build up the link nominal value, tolerance and limit deviations calculations dimensional chain. taking into account systematic effect influence to chain links Existing dimension chain calculation theory is widely used in values. Therefore for dependent link value and tolerances finding design process of new machines and other products. Theory can modified calculation method is used, where dimensional chain also be used in measurement analyse pr
