These lectures would introduce the basic principles of spur and helical gear machining to the reader. First the concept of spur and helical gears would be introduced, followed by their uses, applications, nomenclature etc. A discussion on some commonly used machine elements would follow, which are required in subsequent lectures. Next, the concept of gear milling(including simple and differential indexing), gear shaping and gear hobbing for machining both straight spur and helical gears would be discussed. At every stage â€“ there would be discussions on a number of numerical problems and multiple choice questions.
