Use Value

Manufacturing adds value to materials as they become discrete products and are marketed. Because this value is added in individual stages during the creation of the product, the utilization of value analysis is important.

Use value reflects the functions of the product.

(Kalpakjian S. & Schmid S., Manufacturing Engineering and Technology, p.1266)

Esteem Value

Manufacturing adds value to materials as they become discrete products and are marketed. Because this value is added in individual stages during the creation of the product, the utilization of value analysis is important.

Esteem value (prestige value) reflects the attractiveness of the product that makes its ownership desirable.

Hundred-Percent Inspection

When inspection is conducted by humans, there is no guarantee that %100 of the defective parts will be found; because of fatigue and boredom, human inspection is only 80-85% effective.

Direct Shell Production Casting

The Direct Shell Production Casting (DSPC) process, is similar to the 3DP process except that it is focused on forming molds or shells rather than 3D models. Consequently, the actual 3D model or prototype must be produced by a later casting process. As in the 3DP process, DSPC begins with a CAD file of the desired prototype.

Two specialized kinds of equipment are needed for DSPC: a dedicated computer called a shell-design unit (SDU) and a shell- or mold-processing unit (SPU). The CAD file is loaded into the SDU to generate the data needed to define the mold. SDU software also modifies the original design dimensions in the CAD file to compensate for ceramic shrinkage. This software can also add fillets and delete such features as holes or keyways that must be machined after the prototype is cast.
