N320
changes only the Z position to the value -8.464 as a result of the
MOVT
command. As
only the table can be rotated, the tool orientation remains unchanged parallel to the machine
Z direction, even if the Z direction of the active frame is rotated by 45 degrees.
N330
deletes the basic or system frame; thus the frame definition from
N280
is undone.
In
N340
,
TCOFR
specifies that the toolholder with orientation capability is to be aligned
according to the active frame. Since a rotation is no longer active in
N330
due to the
PAROTOF
command, the initial state is applied. The frame offset becomes zero.
N350
thus approaches the position X10 X10 Z0 (= Z-13 + tool length). Note: Through the
simultaneous programming of both rotary axes A and B the actual position of the toolholder
with orientation capability is made to match that used in
N340
. The position approached by
the three linear axes is dependent on this position, however.
In
N360
, solid angles are used to define a plane whose intersecting lines in the XZ and in the
YZ plane each form an angle of +45 degrees or -45 degrees with the X or Y axis. The plane
defined in such a way therefore has the following position: the surface normal points towards
the solid diagonals.
N370
traverses to the position X20 Y0 Z0 in the new coordinate system. Since the tool is
deselected with
D0
at the same time, there is no longer an additional offset in Z. Since the
new X axis lies in the old XZ plane, this block reaches the machine position X14.142 Y0 Z-
14.142.
N380
only traverses on the Y axis in the rotated coordinate system. This leads to a motion of
all three machine axes. The machine position is X5.977 Y16.330 Z-22.307.
N390
approaches a point on the new Z axis. Relative to the machine axes this is thus on the
solid diagonal. All three axes thus reach the position 11.547.
