160 4 Cycle Programming
4.5 Recessing cycles
Examples of recessing cycles
Recess outside
The machining operation is to be executed with the
"Recessing, radial—Expanded" cycle, taking oversizes
into account (see figure at upper right). This contour
area is to be finished subsequently with the
"Recessing radial, finishing—Expanded" cycle (see
figure at lower right).
The rounding arcs in the corners of the contour valley
and the oblique surfaces at the contour start and end
are also machined in "expanded mode."
Be sure to enter the correct values for the parameters
"contour starting point X1, Z1" and "contour end point
X2, Z2." These parameters determine the cutting and
infeed directions—in this example, external
machining and infeed in negative Z-axis direction.
Tool data
Lathe tool (for external machining)
WO = 1—Tool orientation
K = 4—Cutting width (4 mm)
