ii Preface This solutions manual is intended to assist instructors in the organization of assignments and discussions associated with courses in manufacturing engineering, and using the textbook Manu- facturing Engineering and Technology, 6th ed. In addition to these solutions, instructors can find other education resources at the Prentice Hall maintained website, and Steven Schmid’s website, manufact. Manufacturing presents a number of challenges and opportunities to instructors. As a topic of study it is exciting because of its breadth and unending ability to provide fascinating opportunities for research, analysis, and creativity. Literally every discipline and sub-discipline in engineering has strong ties to manufacturing, and a number of universities have used design and manufacturing as the basis of a capstone course that culminates a mechanical engineering bachelor’s degree. To students of manufacturing, it is, at first, a field so enormous that any semester or academic year sequence in manufacturing can do nothing but scratch the surface of the subject. This perception is absolutely true; manufacturing, like so many other areas of specialization within engineering, truly is an area where lifelong learning is necessary. As educators, we have a responsibility to prepare our students as best we can for a life of continued education. Lifelong learning need not be restricted to formal classroom training, but it should be impressed upon students that they need to continually and systematically examine the physical world in order to achieve continued levels of improvement. A challenging question, and perhaps one without any one good answer is: how should one teach an effective manufacturing course? We have seen examples of many successful strategies, some based solely on analytical methods, others involving surveys of manufacturing, and again others emphasizing the impact of manufacturing on engineering design. Most instructors develop hybrid approaches that are not restricted to any one area. We have attempted to include problems at the end of every chapter to accommodate each of these approaches, and it is our hope that instructors will find good homework assignments in the book. Manufacturing is a challenge to instructors. There are a number of courses, such as statics, dy- namics, solid and fluid mechanics, etc., where topics for study are broken down into small enough portions and where closed-form, quantitative problems are routinely solved by students and by faculty during lectures. Such problems are important for learning concepts, and they give students a sense of security in that absolute answers can be determined. In manufacturing practice, such closed-form solutions do exist, but they are relatively rare. Usually, multiple disciplines are blended, and the information available is insufficient to truly optimize a desired outcome. In practice, manufacturing engineers need to apply good judgment after they have researched a problem as best they can given budgetary and time restrictions. These difficult

What students are saying

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
