4.4 Roughing Cy
cles
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.
This cycle machines the area defined by X1/Z1, X2/Z2 and plunging
angle A, taking the oversizes into account.
Cycle parameters
 X, Z starting point
 X1, Z1 contour starting point
 X2, Z2 contour end point
 P infeed depth: Maximum infeed depth
„ P>0: Machine contour outline.
„ P<0: Retract by the safety clearance at 45°.
 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
„ 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.
