For a point on the other end of a ball-end tool, or on either of the two ends of a flat-end tool, the normal is along the tool axis, i.e., either w or -w. To find the normal at any point on the side of the cylinder, the following parametric definition of the axis of the cylindrical tool is used. P = B + tw, 0 ::; t ::; h ( 4.27) or, ( 4.28) Each point P on the axis lies at the center of a cross-section circle of the cylinder and every point on the cylinder lies on exactly one such cross-section. For any (x, y, z) on the cylinder and corresponding (Px, Py, Pz) on the axis, the normal is given by the following equations.
