The author of this diploma thesis deals with the Proposal of a Risk Analysis Procedure in Technological Preparation for Foundry. Risk management is not currently applied in much detail at this present time. Analysis of the present risk management process in serial and prototype model tools will lead to the identification of risks within this discussion. It is then proposed for corrective actions for improvement of managing the current status to be presented and discussed. Target of this thesis is therefore the proposal of an updated risk analysis procedure in technological preparation for foundry.
