This paper presents a mathematical model to find the wheel location in grinding a given helical flute of an end mill. Two new setting parameters are introduced to define the relative wheel location in workpiece coordinates. This model allows the wheel-axis orientation be expressed explicitly as a function of the design factors and machine setting parameters. By utilizing this explicit form of the wheel orientation and analyzing the influence of setting parameters on design parameters, a new efficient search algorithm is proposed, and the performance shows that the required wheel location is found within 1.5 s to machine a given flute profile. Moreover, the rake angle can be produced more precisely compared with the conventional methods, which have been used with approximations. A comprehensive development of the software for designing and grinding the helical flute of the end mill is presented, which provides a technology and good foundation for the development of a computer-aided design and computer-aided manufacturing (CAD/CAM) system for manufacturing end mills. The results of the experiment, simulation, and design are compared in order to verify of the proposed method.
