Main camshaft.
This solution is convenient when the tools handle the product from more than one
side. However, this example also illustrates the disadvantage of mechanical types of
kinematic solutions, namely, difficulties in transmission of motion from one point to
another. For instance, Figure 4.16 shows what must be done to transform the rota-
tional motion of shaft 1 into the translational motion of rack 2. (Note that the guides
of follower 3, bearings of intermittent shaft 4, and guides of rack 2 are not shown,
although they belong to the design and contribute to its cost.)
