4.4 Roughing Cy
cles
Finishing plunge, longitudinal/transverse—Expanded
Call the "Roughing, longitudinal/transverse" cycles.
Select "Plunge longitudinal" (see figures at right).
Select "Plunge transverse" (see figures on the
following page).
Press the Expanded soft key.
Press the Finishing run soft key.
The cycle finishes the contour area from X1, Z1 to X2, Z2. When the
cycle is completed, the tool remains at the cycle end position.
Cycle parameters
 X, Z starting point
 X1, Z1 contour starting point
 X2, Z2 contour end point
 A plunging angle (default: 0°): Range: 0° <= A < 90°
 W end angle: Range: 0° <= W < 90°
 R rounding
 B1, B2 chamfer/rounding (B1 contour start; B2 contour end)
„ B>0: Radius of rounding
„ B<0: Width of chamfer
 T tool number
 S spindle speed / cutting speed
 F feed per revolution
„ The steeper the tool plunges into the material, the
greater the feed rate decrease (max. 50%).
„ Pay attention to the dimensions of facing tools (see
“Facing tools” on page 419).
Danger of collision!
If the tool angle and the tool point angle have not been
defined, the tool plunge-cuts at the plunging angle. If the
tool and point angles have been defined, the tool plunge-
cuts at the maximum possible plunging angle. In this case,
the resulting contour will not be completely finished and
may need to be reworked.
