High-Productivity Drilling Tools

This completely updated volume covers tool materials, tolerances, an inspection of drilling tools, requirements of tool drawings with examples, and methodologies and procedures of failure analysis. It introduces a new line of HP drilling tools called VPA designs and brings it into sharp focus signifying its importance in drilling operations.High-Productivity Drilling Tools: Materials, Metrology, and Failure Analysis further develops the concept of the metrology of the drilling tools introduced in the first edition. For the first time, the relevant metrological parameters are clearly defined with tolerance for HPHD with practical examples of step-by-step inspection/measurement using advanced tool measurement microscopes and CNC machines. A pros and cons list as a quick and easy decision-making tool for the choice of measuring equipment for a particular application is offered along with practical examples of drilling tool drawings to help tool designers, cutting tool and manufacturing engineers, and users in their everyday activities in the design and selection of HPDT for a particular application. An unparalleled presentation of metalworking fluids (MWFs, a.k.a. coolants) is given and covers all the start of the business: selection, implementation in HPDT and drilling operation, monitoring, and maintenance. A two-step procedure for successful implementation of near-dry machining (NDM) or minimum quantity lubrication (MQL) is presented, and a discussion of the wear of the drilling tool, its proper assessments, and metrics are provided in the evaluation of tool life and quality of machined holes.This practical book should be on the shelves of all industrial engineers, those working in production and manufacturing, process designers, tool material designers, cutting tool designers, and quality specialists. Researchers, senior undergraduate students, and graduate students will also find this book full of very helpful reference information and the source of new ideas and notions in drilling tool development.
