Cut the Fixturing Square

See the fixturing-square instructions and video for additional information on cutting the fixturing square.

A fixturing square [1] establishes an X and Y reference to a known point in the cutting deck. The square provides a stable base for securing parts for cutting, and assists in maximizing material use when cutting. It can be used to precisely locate features on existing parts, or as a convenient surface to secure material against when cutting.

Figure 427  

A square fixture is made by clamping material along the X-front frame in the machine cutting deck, and then using the machine to cut an "L" shape into it. Since the machine cuts the "L," we know it to be true and square to the machine's X- and Y-axes.
