Blanking and piercing are shearing processes in which a punch and die are used to produce parts from coil or sheet stock. Blanking produces the outside features of the component, while piercing produces internal holes or shapes. In normal usage it refers to an ear piercing whereby two helix piercings are connected by a single straight (or curved) barbell. The process is used to create holes, cutouts, and shapes in components, such as engine mounts, gear blanks, and structural members. Blanking and piercing are shearing processes in which a punch and die are used to produce parts from coil or sheet stock. Blanking produces the outside features of the component, while piercing produces internal holes or shapes. Piercing is a metal fabrication technique that creates holes in sheet metal. It uses a punch to penetrate the material, forming an opening without removing any metal. This manual provides technical criteria and guidance for civil works grouting applications. Information on procedures, materials, and equipment for use in planning and executing a grouting project is Included, and types of problems that might be solved by grouting are discussed.
