Abstract

CHAPTER 3 3.1 MECHANICAL DRAWING Engineers communicate their ideas to machinists through mechanical drawings. These drawings contain the minimum information necessary and sufficient to correctly create the part. Shown in Figure 3.1 is a loading platform that will be explained in detail later in this text. Here we show the platform with the arm attached. The aluminum arm moves with the linear motion of the machine, and as shown here for three-point bending, enables contact of the upper bend fixture with the bone placed across the lower bend fixture. The linear slide that the arm is mounted to was purchased from a commercial vendor. To use this slide for the linear motion of the loading platform, it was necessary to design and machine an arm that could attach the testing fixtures to the machine.
