The next illustration (Fig. 1-3) shows the two directions of travel on a TL Series Lathe. To carry the number
line idea a little further, imagine such a line placed along each axis of the machine.
Figure 1-3
The first number line is easy to conceive as belonging to the left-to-right, or “Z”, axis of the machine. If we
place a similar number line along the front-to-back, or “X”, axis, the increments toward the operator are
the positive increments, and the increments on the other side of zero away from the operator are the
negative increments.
The zero position may be placed at any point along each of the two number lines, and in fact will probably
be different for each setup of the machine. It is noteworthy to mention that the X-axis is set with the
machine zero position on the center line of the spindle, while the Z axis zero is set at the finished right of
the part being machined. This will place the entire X axis cutting in a positive range of travel, whereas the
Z axis cutting will be in the negative range of travel.
The diagram shows a front view of the grid as it would appear on the lathe. This view shows the X and Z
axes as the operator faces the lathe. Note that at the intersection of the two lines, a common zero point
is established. The four areas to the sides and above and below the lines are called “QUADRANTS” and
make up the basis for what is known as rectangular coordinate programming.
