Drawing die operation complexity is addressed by decreasing die operation numbers to reduce project budget consumption. Problem-solving techniques identify root causes, then force, blank cutting, and blank location effects are examined alongside process optimization parameters.

It needs to decrease stamping die operation numbers for a part to reduce project budget consumption. Therefore, frequency of tearing, thinning, crack occurrence increase while this amendment. Force, blank cutting, blank location on the drawing die and process optimization were investigated to decrease tearing, thinning and crack occurrence in Transit bodyside inner panels which have over 110 mm. deep drawing process. Formability was improved at the end of this study. Thus production scrap, stoppage time of stamping line were decreased over 90% . This study was conducted at Ford Otosan.  \nKeywords: Stamping, deep drawing, sheet metal forming, drawing die, stamping dies process optimization,  \npress.  \n1. INTRODUCTION  \nProduction cost has increased because of new mobility systems such as self driving, electirification or driving assistance systems in the last 20 years in automotive industry [1-3] . So, new method and optimization systems are investigated by engineers and technicians to decrease budget of projects without reducing quality of final parts on main frame of cars [1]. Raw materials are the first key point of the production budget in automotive industry [3,4].
