The position X17.678 Y0 Z1.536 is approached in
N310
.
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 Since a rotation is no longer active in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.
18.15.1.3 Basic tool orientation example
Basic orientation in the bisector
A milling tool is defined with length
L1=10
whose basic orientation is in the bisector of the X­Z plane.
Description of example:
In
N10
to
N60
, a milling tool is defined with length
L1=10
(
N20
). The basic orientation is in the bisector of the X­Z
plane
N40
to
N60
.
