A surface plate is a solid, flat plate used as the main horizontal reference plane for precision inspection, marking out (layout), and tooling setup. [1]
A spotface or spot face is a machined feature in which a certain region of the workpiece (a spot) is faced, providing a smooth, flat, accurately located surface.
A spot plate, also called a reaction plate, color test plate, [1] or spotting tile (British English), is a laboratory tool made either from ceramics or plastics. [2] Each plate consists of many cavity-like depressions in which only small amount of reactants can be added at a time. [ 3 ]
Bending of plates, or plate bending, refers to the deflection of a plate perpendicular to the plane of the plate under the action of external forces and moments. The amount of deflection can be determined by solving the differential equations of an appropriate plate theory .
Die set (plates). [5] Placement can be inverted depending on the operation, such as use of a knock-out: [6] Die block – the lower (bottom) half of the die set. Machined to conform to the desired shape of the workpiece being formed or cut. Punch plate – the upper (top) half of the die set. Holds and supports the different punches in place.
