5 Programming Tool Movements 5.4 Path Contours – Cartesian Coordinates Chamfer 5-12 The chamfer function permits you to cut off corners at the intersection of two straight lines. You enter the length to be removed from each side of the corner. Prerequisites: • The blocks before and after the chamfer block must be in the same working plane. • The radius compensation before and after the chamfer block must bethe same. • An inside chamfer must be large enough to accommodate the currenttool. • You cannot start a contour with a chamfer block. • A chamfer is only possible in the working plane. • The feed rate for chamfering is taken from the previous block. • The corner point E is cut off by the chamfer and is not part of the resulting contour. To program a chamfer: COORDINATES? L e.g. 5 ENT Resulting NC block: L5 Select the “straight line” function. 1 Fig. 5.15: Chamfer from S to Z 1 S E Fig. 5.16: Tool radius too large Enter the length to be removed from each side of the corner, for example 5 mm.
