Design is about making things good (and then better) and right (and fantastic) for the customer who use and encounter them.
Machine design is defined as the use of imagination, scientific principles and engineering techniques ( the process by which resources or energy is converted into useful mechanical forms, or the mechanisms to create a machine element, machine or system economically, in the desired form as per the needs so has to satisfy the requirements of customer.Machine design or Mechanical Design can lead to the formation of the entirely new machine element, product, machine, system or it can lead to improvement of the existing one.
Thus,Design engineers must study, research and develop different ideas for new products and the systems. They should also be capable of modify the existing products or processes to increase efficiency or improve performance.The Design Process is an approach for breaking down a large project or process into manageable sub tasks or project or process to solve a variety of problems.
