Abstract: A magnetic clamping system and method for locating and holding a workpiece (6), in particular a non-magnetic workpiece (6) within a machine tool (2) and specifically a numerically laser cutting or drilling machine tool. The system comprising at least one magnet (9), and a fixture structure (7), attached to the machine tool, which cooperates and in use engages and supports a portion of the workpiece (6) mounted upon and within the fixture structure. At least one clamp member (11) made of a magnetic material is disposed opposite and facing the at least one magnet (9) with the magnet (9) so that the portion of the workpiece (6) is sandwiched between a clamp member (11) and the magnet (9). A magnetic attractive force between the clamp member (11) and magnet (9) providing a clamping force to hold the workpiece (6). The magnets (9) preferably permanent neodymium magnets.
