![]() Hole-making processes using drilling operations have been the focus of many research studies, where a lot of development and progress has been made. ![]() Therefore, drilling has a significant economic role in industries, where it hugely contributes to the fabrication of various industrial parts. The drilling process is extensively and heavily used in industries, accounting for a large portion of overall machining time and costs. There are many machines that perform drilling operations including dedicated drilling machines, lathes, milling machines, machining centers and special purpose machines. Therefore, the analysis and improvement of this process are of great importance in increasing productivity and competitiveness, where many existing studies reported on the optimization and improvement of this process. Also the effects of using uncoated carbide and high speed steel tools for producing high-quality holes in the formation of built-up edges and burrs are investigated and discussed.ĭrilling is the most commonly performed machining operation in manufacturing industries. An analysis of the holes produced by a multi-spindle head on aluminum alloys Al2024, Al6061, and Al5083 is presented in comparison to traditional single shot drilling. It explains the advantages of using multi-spindle heads to improve the productivity and quality of drilled holes. ![]() This chapter provides an introduction to the drilling process in manufacturing industries which helps improve the quality and productivity of drilling operations on metallic materials. ![]() This subsequently helps industries achieving success and improving the service life of their products. Therefore, a proper selection of machine tools and equipment, cutting tools and parameters is detrimental in achieving the required dimensional accuracy and surface roughness. Automotive and aerospace industries are among those industries which produce millions of holes where productivity, quality, and precision of drilled holes plays a vital role in their success. Drilling is a vital machining process for many industries. ![]()
