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 fo r Determination o f the Pose o f the Grinding Wheel fo r Thin ning Drill Points," Int. J. Mach. Tools Manufi, 47(15), pp. 2218-2229), precise mathe matical modeling fo r drill design and one-wheel grinding o f 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 pro vided with C 1 continuity to eliminate stress concentration points. The mathematical back ground and modeling are summarized in this study. Experimental drills are produced and tested fo r verification and demonstration. The presented modeling technique allows sub sequent researchers to exactly duplicate the drills, including the thinning!notching drill points, a capability that was previously unavailable. This system is useful fo r improved drill CAD and CNC software fo r the design, manufacture, reconditioning, and research o f novel point design. [ D O I : 1 0 .1 1 1 5 /1 .4 0 2 7 4 1 4 ]

“…Hsieh and Lin present a kinematic model to produce multi-flute drills on a six-axis CNC tool-grinding machine. The ability matrix of a six-axis CNC tool-grinding machine is established by the D-H notation (12) . It is worth noting that isometric sketch of a multi-axis machine tool is usually complex, and may easily confuse the reader.…”

Continuing improvements in computer and machine tool technology have led to many new and fascinating applications in CAD/CAM systems. One of the most fruitful areas of CNC machine research is kinematic analysis, which describes the mapping between the set of cutter position and orientation and the set of joint variables. There has thus far been relatively little research into the mapping between the set of joint variables of machine tool and set of joint variables of another machine tool. In this thesis we develop a method called machine coordinate values exchange (MCVE) model, which aims to deal with this kind of analysis. This proposed methodology is a mathematical form, applicable to both academic research and production, and enables the direct and rapid generation of joint variables. This study also presents a novel graph, called an isometric schematic, to conceptualize the prototype of multi-axis machine, and establishes and shows the feasibility of the MCVE model for two different types of machine tools.

“…Analytical methods reported in the literature consider worm machining as helical groove machining and generally use the principles of differential geometry and coordinate transformation to arrive at the worm profile [4][5][6][7][8][9]. However, the tool profile is to be expressed as a mathematical function without any singular points.…”
