Motion Strategy

Electrode jump motion strategy was adopted to fabricate noncircular tool using wire electrical discharge grinding (WEDG). The machining procedure and electrode jump motion strategy for noncircular tool fabrication were determined through experiments. This approach has been verified by successfully machining of rectangular electrode (38μm×38μm, 700μm length) and D-shaped electrode (diameter 45μm, height 42μm, 500μm length). D-shaped array holes of 6×6 matrix were drilled using corresponding single noncircular tool which was manufactured by the adopted machining approach. The array holes have tight diameter tolerance and height tolerance which are both less than 2μm, and positioning errors are both less than 1μm in the direction of the X, Y-axes.

AbstractA series of designed experiments was performed in an attempt to evaluate and quantify the historically “anecdotal” benefits of conformal cooling for injection molding tooling. The study considered different generic part geometries, gating schemes, mold materials, plastic resins and cooling approaches. This paper provides an overview of the mold design approach, cooling simulation, tool fabrication via the 3DP™ process, as well as part molding and inspection results.

Tool Fabrication

The nickel coatings and electroplated diamond tools were fabricated with ultrasonic and without ultrasonic condition. Hardness and adhesive strength of nickel coatings were tested. Diamond grains on tool substrate were observed with microscope. Al2O3 ceramic was machined with fabricated electroplated diamond tools to compare material removal rate and grinding ratio. Experimental results show that high hardness can be obtained under the effect of ultrasonic during tool fabrication processes. Ultrasonic agitation can make grain dense and guarantee nice contact between substrate and coating. With ultrasonic power of 200W, nickel coating presents highest values of hardness and adhesive strength. High grain density of diamond tool can be obtained. During buildup processes, some buildup time is needed to obtain enough thickness of nickel coating before ultrasonic agitation is applied. Grinding ratios of diamond tool with ultrasonic during buildup processes were better than without ultrasonic. The diamond tool fabricated with ultrasonic agitation presents better cutting ability. During tool fabricating processes, the reasonable application of ultrasonic agitation is very important.
