Red Seal Tool and Die Maker Practice Exam

Burrs or sharp edges are a common defect associated with stamped parts due to the nature of the stamping process itself. During stamping, a die cuts or shapes the metal, which can sometimes leave small pieces of excess material along the cut edges. These burrs are often jagged and rough, protruding from the intended shape of the part. This can lead to issues during assembly or operation of the final product, as sharp edges can pose safety hazards and affect the functionality of parts by interfering with mating surfaces. Additionally, burrs may require subsequent deburring processes to ensure the quality and safety of the part before it goes to the next stages of production or assembly. In contrast, while bending of the metal, color fading during production, and misalignment of parts can occur in various manufacturing processes, they are not as intrinsic to the stamping process as the generation of burrs is. Each of these issues pertains to different factors such as material handling, environmental conditions, or equipment setup, which may not directly relate to stamping defects.
