Excerpt from Machine Tool Operation, Vol. 2: Drilling Machine, Shaper and Planer, Milling and Grinding Machines, Spur Gears and Bevel Gears

The preface of Part 1 gives the reasons for preparing this text. Part 1 deals with lathe work, bench work, and work at the forge. An attempt has been made in this volume (part II) to organize the fundamea principles of construction and operation of the Drilling Machine, Shaper, Planer, Milling Machine, and Grinding Machine. A chapter embodying what every machinist should know concerning spur gears and bevel gears is included.

Only fundamentally has this work anything to do with production. Special rapid production machines and tools represent various combinations of fundamental mechanisms, methods and processes. The purpose of this text is to discuss these fundamentals, and build a foundation for rapid production; the same sort of foundation that arithmetic builds for mathematical calculations.

Perhaps a statement regarding the way in which the follow ing text is presented and the reasons therefore should be made here.

First: While there are a great many sizes, types, and kinds of each of the standard machine tools, and while the makers differ in details of design, the fact remains that the primary function, and the basic principles of construction and opera tion of the given class of machine, are the same regardless of the size or where it is made. Therefore, a well-known example of each of the machine tools under discussion has been selected and described, and typical mechanisms illustrated and explained in such a way as to bring out the general details.

Second: The operator's production, interest and progress are in proportion to his understanding of the basic principles of the construction of the machine he is running - the special mechanical features, feed changes, speed changes, and adjust ments of the machine. Consequently, these things have been discussed early in the study of the particular machine.

Third: The broader the student's knowledge concerning the cutting tools used in the given machine, and the quicker he gets a fairly comprehensive idea of the shapes, sizes and characteristics of these tools, the easier and better he can run the machine. Therefore the cutting tools used have been explained in considerable detail.
