PREFACE

The machine tools in this volume divide themselves into two groups, one in which the tools (or work) travel in a straight line, the other group in which they (or it) rotates. The planer and the vertical boring mill have stationary tools and the work moves, the others move the tools and hold the work.

There are, however, certain principles involved which are common to them all. Cutting, speed, clearance, angles, chip clearance and support for the cutting edge are all problems which must be considered in all cutting tools. The solution is not the same in all cases, but an understanding of the principles involved will help in all cases, no matter what the special details.

It has been our aim to show enough examples of the uses of various machines to give a thorough understanding of the principles involved so that adaptations can be readily made to other uses.

This requires both experience and imagination, but the real machinist enjoys solving problems which are out of the ordinary.
