Abstract
A method for efficiently machining magnets with curved surfaces is disclosed. The use of machining equipment capable of making curved cuts through magnetic material can allow significant cost and material savings, particularly when machining magnets with complementary surfaces. A process for using a series of cutting wires to simultaneously cut magnetic material into conformally shaped magnets is described.
Claims11
A method of cutting a magnetic substrate, the method comprising:
- moving a workpiece holder in at least two axes to maneuver the magnetic substrate coupled thereto through a number of cutting wires to form at least two magnets having complementary curved surfaces;
- maintaining a minimum clearance distance between at least two anti-parallel sets of the cutting wires;
- adjusting a pitch value between parallel cutting wires in accordance with one dimension of the magnets;
- and
- removing the magnetic substrate from the wire cutting machine in a single operation after a series of cutting operations,
- wherein the magnetic substrate is held together in a single block by a coating selected from the group consisting of wax and epoxy.
