“…In many cases, clearance was designed and calculated in the groove design process, based on the assumption that it was a straight line at the cross section of end mills [6][7][8][9][10][11][12]. Obviously, clearance models built with this approach could not reflect the actual processing precisely.…”

Clearance of end mills has great impact on the performance of milling, and therefore a high demand for its machining theory and process is put forward. Based on the analysis of practical machining process, enveloping theory, principles of spatial geometry are introduced to establish the clearances processing model, as well as considering the geometries, orientations, and locations of wheels used to machine the clearances with convex, eccentric, or elliptic shapes. Accordingly, limitations of wheel geometry and location to machine a desired clearance are discussed. A commercial computer aided design system with API function programming is used to visualize the machining process. The solid model is finally obtained.

“…The mathematical models start by deriving the cutting edge equation of the revolving surface of the cutter. The equation is derived by considering constant helical angle to the generatrix [1][2][3][4][5], constant helical angle to the revolving axis [6][7][8], constant pitch [9,10] or in some situations combination of two [11].…”

“…Once the mathematical equation of the cutting edge is derived, the principle of reverse engineering is employed in order to generate a wheel profile that grinds a tool flute matching precisely the designed one. With this approach, Chen and Chen [5] generated a wheel profile in order to produce a fillet-end mill with a concave-arc generatrix, Lin and Lai [6] obtained a wheel profile to produce a cylindrical ball-end mill, Chen and Chang [7] developed a wheel for a circulararc ball-end mill, Chen and Wang [8] build the wheel for a concave-arc ball-end mill.…”

The traditional cutting tools grinding reveals inexact tool flutes that altered the tool strength and affect the chip evacuation capabilities. Moreover, the normal rake angles are neither exact nor varying smoothly on the rake face along the cutting edge. Adopting the rake face grinding process, the wheel shape and path are optimized using GODLIKE scheme in order to grind the tool flutes with exact helical and normal rake angles while keeping close matching to the designed flutes. A tapered ball-end mill is considered in this study due to its extensive role in five-axis sculpture surfaces machining. With this approach proposed, a simple grinding wheel replaces the complex wheels commonly used, and the deviation between the designed and the generated flutes reveals less than 4 % of the tool minor radius. Beside all, a relationship between the radial and the normal rake angles are established.
