Introduction

Abstract

The vast strides made by engineering in the past few decades are due primarily to close cooperation between scientists, designers, and production experts. The designer’s role in this activity is to be an intermediary between scientific knowledge and the production side. Since his part often fails to attract for the designer the prestige which is his due, it must be pointed out that he has the very responsible task of satisfying in the best manner possible the conditions laid down in the customer’s order, and thereby providing the essential foundation for economic manufacture. The finest workshop facilities with the most up-to-date machine tools enabling economic manufacturing methods to be used are of no avail if the designer has not done his work satisfactorily.
