1. A machining fixture for a wire electrical discharge machine having an electrical discharge wire, comprising a plurality of member holes, each member hole of said plurality of member holes being configured to accommodate a workpiece;
wherein said machining fixture is configured to perform two cuts on each of plurality of workpieces accommodated in each of said plurality of member holes, said two cuts being performed in a first cutting plane and a second cutting plane; and
wherein said plurality of member holes are sequentially arranged in an inclined plane so that when a translating straight line of said electrical discharge wire is substantially orthogonal to said first cutting plane, the translating straight line of said electrical discharge wire cuts no more than one workpiece of said plurality of workpieces in a first cutting direction, and when the translating straight line of said electrical discharge wire is substantially orthogonal to said second cutting plane, the translating straight line of said electrical discharge wire cuts no more than one workpiece of said plurality of workpieces in a second cutting direction when said plurality of workpieces are mounted in respective member holes of the plurality of member holes of the machining fixture.
