A third step of forming a target workpiece and a cavity by cutting the target workpiece and the periphery of the workpiece on one surface of the metal member, and processing by the third step. The fourth step of applying a release agent to the surface of the mold and the fifth step of pouring the melted resin into the one surface of the mold coated with the release agent.
And, after the resin is solidified, the non-ferrous metal member is removed from the pedestal and fixed to the pedestal with a fixing screw so that the other surface, which is the opposite surface of the one surface, is visible. It comprises the step 6 and the seventh step of cutting the target workpiece from the other surface of the non-ferrous metal member.

Working The present invention, by cutting one surface of the material with the above configuration, applying a release agent for facilitating the removal of the processed product on the processed surface, pouring the resin solution, by the solidification action of the resin, Since the workpiece is fixedly held and the cutting is performed, the processing time can be shortened.

Example An example of the non-ferrous metal processing method of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view in which a cutting tool for a machining center is used to machine a cutting reference hole and a mounting hole on a first machining surface, and FIG. 2 is a perspective view in which a material is fixed to a pedestal with fixing screws 3 and 4 are perspective views in which the first machined surface is machined into the shape of the surface side of the workpiece, FIG. 4 is a plan view showing the surface side of the workpiece, and FIG. FIG. 6 is a perspective view in which a mold release agent for molding is applied to the subsequent first processed surface, FIG. 6 is a perspective view in which a resin solution is poured into the first processed surface of the release agent coating liquid, and FIG. After the resin solution is solidified, the material is inverted so that the second processed surface becomes the front side, and is cut into the shape of the back side of the work piece. FIG. 8 shows the back side of the work piece. The plan view shown in FIG. 9 is a perspective view in which the workpiece is taken out of the resin after the cutting process is completed.

To process an aluminum flat plate as a non-ferrous metal member, first, as shown in FIG. 1, a material 4 made of an aluminum flat plate with both sides flat.
Using the cutting tool 10 of the machining center to machine the cutting reference hole 12 and the mounting hole 7, insert the reference pin 13 into the cutting reference hole 12 as shown in FIG. The fixing screw 11 is inserted into the hole 7 to fix the material 4 to the pedestal 3.

Next, using the cutting tool 10 of the machining center as shown in FIG. 3 for the first machined surface 8 shown in FIG. 1, the surface 1 side of the workpiece 1 as shown in FIG. 4 is formed. Perform cutting. At this time, since a cavity for pouring a resin solution, which will be described later, is required, processing is performed so that the position of the uppermost surface 1a of the processed material 1 is lower than the height of the unprocessed material surface 4a of the material 4.

After it as cutting shown in Figure 3, for ease of taking out the workpiece 1 from the material 4, the molding mold release agent 5 as shown in FIG. 5, about per 1 m ² on the surface of the workpiece 1 150cc
