Machining of Metals

A faceplate is a large circular disk with radial plain slots and T-slots in its face. The workpiece can be mounted on it with the help of bolts, T-nuts, and other means of clamping. The faceplate is usually employed when the workpiece to be gripped is large or noncircular or has an irregular shape and cannot, therefore, be held in a chuck. Before any machining operation, the faceplate and the workpiece must be balanced by a counterweight mounted opposite to the workpiece on the faceplate, as shown in Figure 11.16.

The composite structure consists of a two-layer ceramic-metal armor and a poly-methyl methacrylate (PMMA) target layer shown in Figure 1, schematically. The faceplate is a silicon carbide (SiC) ceramic, and the backplate is RHA steel. The TNT spherical charge is located at the stand-off distance of from the upper layer. and are the plate diameter, ceramic thickness, steel thickness, and target layer thickness, respectively. The size of the elements of the water environment is generated according to Eq. (6) [18]: where and are the water density, plate density, water element thickness, and plate thickness, respectively.
