Examples of recessing cycles
Recess outside
The machining operation is to be executed with the Recessing
radial E cycle, taking oversizes into account. This contour area is to
be finished subsequently with
Recessing radial finishing E
.
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
Start point contour X1
,
Z1 and End point contour X2 , Z2 parameters. These parameters
determine the cutting and infeed directions—in this example,
external machining and infeed in negative Z-axis direction.
Tool data:
Turning tool (for external machining)
TO = 1 – Tool orientation
SB
= 4 – Cutting width (4 mm)
