If the machine tool you are modeling does not contain any rotary slides, and all the remaining slides are positioned orthogonally to each other, you probably do not need any more junctions. However, if your machine tool contains rotary slides, you need to create a junction that defines the center of rotary motion for each rotary slide on the machine, unless the centers of the rotary tables are not offset. In our example, there are two rotary tables - a primary and secondary. The centers of the rotary tables are not offset, so we can create just one junction which can be used to describe both axes of rotary motion.</p>
