Advantages: One of the greatest advantages of 3-D software is its ability to convey what the designer wants. As a die-maker, I spent countless hours thumbing through 2-D die designs (see Figure 1), trying to figure out just what that particular die section looked like. With todays 3-D technology (see Figure 2), a die-maker can view any component in the die as a 3-D entity and rotate it, enlarge it, reduce it, cut a section through it, and measure it. Advantages and Disadvantages of Designing Dies 3-D Unit 9 EXERCISE With today’s 3-D technology, a die-maker can view any component in the die as a 3-D entity and rotate it, enlarge it, reduce it, cut a section through it, and measure it. Another advantage of 3-D software is that it provides a solid model of each die component, which can aid in the machining process. When dies are designed in 2-D, a machinist often must create a 3-D model (surfacing) from the 2-D designs. From this 3-D model, the machinist can create a tool path and program the mill to cut the desired shape. Designing in 3-D eliminates the process of creating the solid model for machining purposes. Sophisticated design software can communicate directly with milling machines to create cutter paths for all of the die components that need to be machined. In addition, certain design software can determine quickly if any interference issues need to be addressed when the die is fully closed. Disadvantages: First, 3-D design software can be very expensive. It might be worth the investment, however, if it eliminates confusi
