Abstract:  
This manual on blast cleaning is a companion to the one published on shotpeening. It is intended to help engineers, management, and shop personnel to increase their knowledge of the process. The information contained herein has been submitted and edited by a group that has had extensive and varied experience with blast cleaning and whose recommendations merit consideration. Blast cleaning may be defined as a secondary manufacturing process in which a suitable stream of solid particles is propelled with sufficient velocity against a work surface to cause a cleaning or abrading action when it comes in contact with the workpiece. As indicated in the definition, blast cleaning may be employed for a variety of purposes. Ordinarily, it is considered as a method for removing sand from castings; burrs or scale from forgings, mill products, or heat-treated parts; to promote machinability; and to minimize the possibility of interference in actual operation. In addition to this use, blast cleaning also produces an excellent surface for industrial coatings. All of these objectives are often accomplished in the one operation.
