The best question to ask is whether the material produces strong steel pressure vessels that can withstand the hardness testing for the mechanical behavior of materials. The other question is how the material affects the cost, performance, size, and shape of the component produced. CES applies a simple and strong technique to assist in selecting the materials.

In the selection of process, the aim is to select the best methodology for manufacturing a specific component. This is done through a systematic procedure in consideration of the target result and the safety precautions. For example, the process in this experiment was to take the measurements of the Rockwell hardness of a number of ferrous and non-ferrous metals and alloys. The selection is done through a computer-based correlation of mechanical property. The components in this experiment include pressure vessels and milk cartons. The features of a good process are the guiding principles for the choice of the process. The features include low cost, high quality of the manufactured components, and utilization of minimum resources. The question to be asked in the selection of the best process is whether the process gives the strongest large steel pressure vessels at a lower cost and low resource demand. The methodology used in this experiment is CES. It assists in the selection of the materials and processes in a very similar manner, with each approach relying on the ideas of the critical questions that were asked. The other possible methodology to be applied is Rockwell testing (Budinski & Budinski 2005, p. 65). The tests for hardness are done as a direct reading a digital display or an analog dial because of the difference in the intensity of the penetration during the test cycles.

The task in this experiment is to use the CES software for the selection of materials and the processes. The purpose of this experiment is to take the measurement of the Rockwell hardness for many ferrous and nonferrous samples packaged&nbsp.in accordance with the ASTM specifications.
