Man's technological ascent began in earnest in what is known as the Neolithic period ("New stone age"). The invention of polished stone axes was a major advance because it allowed forest clearance on a large scale to create farms. The discovery of agriculture allowed for the feeding of larger populations, and the transition to a sedentist lifestyle increased the number of children that could be simultaneously raised, as young children no longer needed to be carried, as was the case with the nomadic lifestyle. Additionally, children could contribute labor to the raising of crops more readily than they could to. | Process Planning The design manufacture interface by Peter Scallan ISBN 0750651296 Publisher Elsevier Science Technology Books Pub. Date December 2002 Preface Most prefaces tend to focus on the technical content of the textbook why the author felt the need to write it what makes it different and most of all why readers should buy it. However this was such an extraordinary learning experience for me that I thought I should share some of it with you. Near the end of session 1998-9 1 was asked as Programme Leader for a then HND BSc Manufacturing to consider revamping the course. During the process of developing this new programme the focus of which was manufacturing management and in particular manufacturing planning and control I was developing a curriculum for a module on process planning. As part of this a number of references for library resources had to be identified. Although there were many fine textbooks on computer-aided process planning and for postgraduate research there appeared to be none that were particularly suitable for undergraduate study. Furthermore as the emphasis of the module was on the skills and knowledge required for process planning and not on the technology I needed a textbook that was easy for undergraduates to follow while being reasonably thorough. Having contacted a number of publishers it became apparent that here was an excellent opportunity to write and publish my first book. After all I had written and published distance learning material and how difficult could it be If only I knew then what I know now Having estimated that it would take me about eighteen months to write the book I finally finished in October of 2002 18 months late During this time there was a major illness in the family a car written off a disastrous house move the birth of our fifth daughter not a typing error I hasten to add and so many changes with my job that would require a book for themselves. However imperfect it may be I was determined to finish it and .
