The objective of the study is to utilize the cross-sectional computation capabilities of a computer to calculate the revolutions per minute, to determine the volume of metal being removed by the machine cutter at any point in the programmed path, and to output the feed rate that the particular situation requires. The six chapters which present the information are as follows: Chapter I, introduction; Chapter II, analysis of factors affecting the computation of speed and feed rate parameters; Chapter III, organization of the input by the numerical control programmer; Chapter IV, modifications to the computer software; Chapter V, evaluation of the benefits of utilizing computed speed and feed rates; Chapter VI, summary, findings, conclusions, and recommendations.

The primary purpose of this study is to give simple and detailed instructions for building a log cabin by the post-and-beam method. The data were gathered from three sources: (1) library research, (2) interviews with experienced builders of cabins, and (3) personal experience in cabin construction. A step-by-step guide for building a cabin is given in Chapters II and III, which explain in depth how to construct each section of the cabin, from laying the foundation to putting on the finishing touches. It is believed that any serious builder can follow the directions and construct his own log cabin for less than one-third the cost of a similar commercially built cabin.
