Materials management is a core supply chain function and includes supply chain planning and supply chain execution capabilities. Specifically, materials management is the capability firms use to plan total material requirements. The material requirements are communicated to procurement and other functions for sourcing.
Certain chemical process yield important basic materials for society, e.g., (cement, steel, aluminum, and fertilizer).However, these chemical reactions contribute to climate change by emitting carbon dioxide, a greenhouse gas, through chemical reactions, as well as through the combustion of fossil fuels to generate the high temperatures needed to reach the activation energies of the chemical ...
Manufacturing provides important material support for national infrastructure and also for national defense. On the other hand, most manufacturing processes may involve significant social and environmental costs. The clean-up costs of hazardous waste, for example, may outweigh the benefits of a product that creates it. Hazardous materials may ...
Material selection is a step in the process of designing any physical object. In the context of product design, the main goal of material selection is to minimize cost while meeting product performance goals. [1] Systematic selection of the best material for a given application begins with properties and costs of
Steel is made from iron and carbon. Cast iron is a hard, brittle material that is difficult to work, whereas steel is malleable, relatively easily formed and versatile. On its own, iron is not strong, but a low concentration of carbon – less than 1 percent, depending on the kind of steel – gives steel strength and other important properties.
Material efficiency is a description or metric ((Mp) (the ratio of material used to the supplied material)) which refers to decreasing the amount of a particular material needed to produce a specific product. [1] Making a usable item out of thinner stock than a prior version increases the material efficiency of the manufacturing process.
[3] U.S. EPA's SMM lifecycle of materials and products from material extraction, manufacturing, distribution, use and end-of-life.. Sustainable Materials Management (SMM) represents a framework to sustainably manage materials and products throughout the entire lifecycle, from resource extraction, design and manufacturing, resource productivity, consumption and end-of-life management.
Milling is the complex shaping of metal or other materials by removing material to form the final shape. It is generally done on a milling machine , a power-driven machine that in its basic form consists of a milling cutter that rotates about the spindle axis (like a drill ), and a worktable that can move in multiple directions (usually two ...
