.... Cutting is basically accomplished through an erosion or shear process. In the case of abrasive water-jet cutting, the sharp edges of each grain of abrasive are worn down by impact with the workpiece. This reduces its cutting efficiency, and it is both impractical and uneconomical to recover and reuse it...

For this reason, water-miscible fluids sometimes cause foaming problems in operations such as gundrilling or flatbed and double-disk grinding. With the use of special wetting agents and...

... is limited to round tool configurations. Conventional abrasive jet machining is the use of abrasive-gas jets to propel particles against a surface and remove the material from that surface via particle impact and shear. Typically, abrasives in quantities up to 0.05 kg/min (0.1 lb/min) are propelled...

... the quill, the end butts against a wire stop or stock gage to determine the length of the blank to be headed. The shear actuates to cut the blank. The blank then is pushed out of the shear into the transfer, which positions the blank in front of the heading die. A newer technique consists of a linear...

...-carbon alloy steels in diameters to 125 mm (5 in.). If section thickness and hardness of material permit, it is usually economical to shear as many bars in one cut as possible, using multiple-groove shear blades. It is common practice to use multiple shearing on low-carbon steel up to 50 mm (2 in.) in...
