Basic Math For Ballnose Tools. The ballnose end mill is a special sort of tool. Its ability to mill up and down the contours of complex surfaces makes it invaluable to mold shops and other makers of 3D forms. And yet, the tool is lacking in a capability one might take for granted in other cutters: the ability to machine a flat surface.
ادامه مطلب5-axis ball-nose cutter of diameter 1.2 in. (b) 5-axis flat-end cutter of diameter 1.2 in. (c) 3-axis ball-nose cutter of diameter 1.2 in. (d) 3-axis flat-end cutter of diameter 1.2 in. For all cases, assume that the number of passes is 5 and the tolerance is 0.001. For each case, calculate CL data at points A, B, C, and D.
ادامه مطلبMachining is most commonly done with ball end mills (having a hemispherical end), flat end mills (having a flat bottom), and bull-nose end mills (having a flat bottom with a fillet radius between the bottom of the tool and the shank). These cutters are generally oriented perpendicular, or close to perpendicular to the surface.

ادامه مطلبCommon 3-axis CNC milling machines are generally equipped with 2D tool radius compensation (2D-TRC), which can realize TRC function for the contours in three basic planes when flat end mills are used. The 2D-TRC function makes engineers to program according to the actual contour of a part, and avoids over-cut phenomenon. Unfortunately, the 2D-TRC is …
