Coordinate Measuring Machine

Coordinate measuring machines are important developments in measurement technology. Basically, each consists of a platform on which the work piece being measured is placed and then moved linearly or rotated. A probe, attached to a head capable of lateral and vertical movements, records all measurements. Coordinate measuring machines also called measuring machines, are very versatile; they are capable of recording measurements of complex profiles with high sensitivity(0.25 m) and with high speed.

Belt Sanding

The term belt sanding refers to the light grinding applications in which the work part is pressed against the belt to remove burrs and high spots, and to produce an improved finish quickly by hand.

Interface

There is always an interface between constituent phases in a composite material. For the composite to operate effectively, the phases must bond where they join. In some cases, there is a direct bonding between the two ingredients. In other cases, a third ingredient is added to promote bonding of the two primary phases. Called an interphase, this third ingredient can be thought of as an adhesive. An important example is the coating of glass fibers to achieve adhesion with thermosetting resin in fiberglass-reinforced plastics. This case results in two interfaces, one on either boundary of the interphase. Finally, a third form of interface occurs when two primary components are not completely insoluble in each other; in this case, the interphase is formed consisting of a solution of the phases. .
