Reports on Industrial Engineering Findings from National Cheng Kung University Provide New Insights (Computer Numerical Control Grinding Wheel Pose for Thinned/Notched Drill Points With Specifiable Secondary Cutting Edge and Characteristic ...)

By a News Reporter-Staff News Editor at Journal of Engineering -- Current study results on Industrial Engineering have been published. According to news reporting out of Tainan, Taiwan, by VerticalNews editors, the research stated, "Researchers commonly develop notched drill points with secondary cutting edges that have unusual specifications; however, mathematical models cannot comprehensively specify these thinned/notched drill points. In an earlier work (Lin, P. D., and Tzeng, C. S., 2007, 'New Method for Determination of the Pose of the Grinding Wheel for Thinning Drill Points,' Int. J. Mach."

Our news journalists obtained a quote from the research from National Cheng Kung University, "Tools Manuf., 47(15), pp. 2218-2229), precise mathematical modeling for drill design and one-wheel grinding of ISO-standard drills with linear secondary cutting edges was presented. That model is expanded herein to drill points with a specifiable secondary cutting edge and characteristic angle distribution. Optionally, the entire cutting edge (primary, secondary, and chisel edges) can be provided with C-1 continuity to eliminate stress concentration points. The mathematical background and modeling are summarized in this study. Experimental drills are produced and tested for verification and demonstration. The presented modeling technique allows subsequent researchers to exactly duplicate the drills, including the thinning/notching drill points, a capability that was previously unavailable."

According to the news editors, the research concluded: "This system is useful for improved drill CAD and CNC software for the design, manufacture, reconditioning, and research of novel point design."
