Machining Data for Numerical Control Drilling

Download or read book Machining Data for Numerical Control Drilling written by Michael Field and published by . This book was released on 1966 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents an extensive set of machining data selected from six USAF Machinability Reports. Data are tabulated and arranged in formats including machining variables such as tool material, tool geometry, cutting fluid, depth, feed, and tool life end point. For each of the data lines, the relationship between tool life and cutting speed is expressed in at least three sets of data, thereby making it possible to optimize for maximum production or minimum cost. While these data are expected to be of considerable assistance in providing data for numerical control applications, they are also of great value in any type of machining situation involving the materials for which machining data are presented. Specifically this report, the third of a series, pertains to drilling.
