<p>A cutter (10, 200) capable of cutting multiple intersecting faces in an elongate workpiece (34) at precisely controlled angles or two faces at precise offsets in an elongate workpiece (34) that can be pivoted about its longitudinal axis. The cutter (10, 200) being able to accurately make two or more intersecting or spaced apart cuts in the workpiece by adjusting the orientation of a workpiece holding means (28, 30, 32, 228 and 230) with respect to a cutting means (22, 24, 26, 222, 224 and 226) in an x direction and at least two other directions chosen from a set including: y, z,α,βandγ, where the x, y and z directions are orthogonal Euclidean directions and theα,βandγdirections are polar angular directions. The workpiece (34) being pivotable about a longitudinal axis that is contained within its cross sectional area, rather than being pivotable about a longitudinal axis disposed upon the outer surface or outside of the workpiece (34).</p> |
