Recess inside
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).
As the "plunge width P" is not input, the MANUALplus
plunge-cuts with 80% of the plunge-width of the tool.
In expanded mode, the chamfers are machined at the
start/end of the contour.
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, internal machining
and infeed in negative Z-axis direction.
