4.4 Roughing Cy
cles
Examples of roughing cycles
Roughing and finishing an outside contour
The shaded area from "AP" (starting point of contour)
to "EP" (contour end point) is first rough-machined
with the cycle "Cut longitudinal—Expanded," taking
oversizes into account (see figure at upper right). This
contour area is to be finished subsequently with the
cycle "Finishing cut longitudinal—Expanded" (see
figure at lower right).
The rounding and the oblique cut at the contour end
are also machined in "expanded mode."
The parameters for contour starting point X1, Z1 and
contour end point X2, Z2 determine the cutting and
infeed directions—in this example, external
machining and infeed in negative X-axis direction.
