In practice, the flutes of end mills are ground using CNC grinding machines via controlling the grinding wheel's position and orientation to guarantee the designed flute parameters including rake angle, flute angle, helix angle, and core radius. However, for the previous researches, the designed flute profile was ground via building a specific grinding wheel with a freeform profile using ...

In solid carbide endmills, the flutes significantly affect the tool's cutting performance and life, and the core radius mainly affects the tool's rigidity. The current CNC programming techniques can correctly determine the orientation of the wheel so that it grinds the rake face with the specified rake angle; however, it cannot accurately determine the wheel location for the direct method and ...

Associate Editor, Modern Machine Shop. On its surface, grinding seems simple: a machine takes a rotating tool (usually a wheel) with abrasive grains and applies it to a workpiece's surface to remove material. Each grain is its own miniature cutting tool, and as grains dull, they tear from the tool and make new, sharp grains prominent.

A simple geometric and optimal method is adopted for the fiveaxis CNC grinding of the endmill cutters. In this research, initially a simplified parametric profile of the grinding wheel is constructed using line segments and circular arcs. The equation of the wheel sweptsurface in fiveaxis grinding is derived. Then subjected to the flute profile design, the profile parameters of the ...

In operation, the grinding wheel is positioned within inch of the workpiece using the machining center's positioning system. For the final size, the fine feed slide on the head takes over to grind the remaining stock. Motion control for this axis is available either as a standalone unit, or it can be integrated into the machining center CNC.
