Investigation of Burr Height for Sheet Metal Process of Medium Duty Casters in Industrial Kitchens

Abstract

Sheet metal processing is a cheap, automated metal processing method that is frequently preferred in many different industries. Holes, slots and gaps of different geometry on sheet metal surfaces are generally required at various processes. These manufacturing are performed with punches and dies. In this study, holes were punched into ASTM A1011 low carbon sheet metal with punches made of AISI D3 tool steel and the maximum burr heights in the flank materials were measured. In general, the quality of the parts coming out of the punch is determined by tool wear and burr height. For this reason, maximum burr height of piercing materials was measured in this study. As a result, it was observed that the burr heights increased with increasing strokes. Intensive plastic deformation and wear in the tool increased the burr height in the blank. The highest burr value was obtained with 118 μm and 60,000 strokes.
