    If you look back in history, there was a time when everything was made by hand. This required a great deal of time and craftsmanship to make only one tool or item. Machine tools have played a major role in all historic technological advances in manufacturing.

    Without machine tools, there would be none of the important products that our society relies on every day. Items such as cars, airplanes cell phones or even computers. In the world of manufacturing and specifically precision manufacturing there is a family of machines utilized in the majority of all metal working. These machines are designed specifically to drill, mill, turn, grind and form metals or plastics. Each of these has very unique advantages and is designed to hold extremely close tolerances in each area of specialization.

    Very rarely can a manufacturer produce parts solely on one type of machine tool. In today’s advanced technologies in medical, aerospace and defense industries, the capabilities of machine tools are critical to a company’s success. Also, in a world of constant global competitiveness, the country with the most advanced machine tools will have a strongest economy.

    Perform research online on how the economy is affected by levels of manufacturing. You only have 15 minutes to complete this assignment. You will return to the class discussion and share the information from your research.

  • Section 2 Design: Manufacturing and Sustainability

    People all over the world are brainstorming new ideas for processes and products. This entrepreneurial spirit is how so many advancements have made our lives better. But, in most cases ideas or products would simply be too expensive to produce or would create a very negative environmental impact. When products are in the design phase, it is important to consider both of these issues. This is called design for manufacturability and sustainability. The two terms have separate definitions and purposes but are high intertwined with each other.

    Design for manufacturability is the engineer’s ability to design products in such a way that they are easy to manufacture. This basic concept exists in most engineering disciplines, but of course the details differ widely depending on the manufacturing technology. This important skill for the engineer is to focus not only on the design aspect of a part but also on the producibility or the effort it would require manufacturing the product.

    Designing for sustainability refers to the environmental impact of the design. Environmental impact of any industry has become a very common issue in our world and any time that is in question it impacts the social, economic and ecological implications. The intention of sustainable design is to limit negative environmental impact completely through skillful, sensitive design. Another goal of sustainability is to create products that will impact the behavior and views of the individuals that will use it through a renewed interest in environmental issues.
