G46
is
also
reset
with

TRA
and
Interpolation:
o TRA
is
pennitted with the following interpolations:
GO,
G
I,
G2, G3, G5, G6, G75, thread milling
with
infeed
in
X.
r&-entry
function.
o If TRA is active, the working plane (G17, G18, G19) cannot be changed,
o
G20
(polar
coordinate
programming)
is
possible
if
the
polar
coordinates
refer
to
the
active
working
plane.
Example:
N17
G17
N12
G20
X
..
N13
G20
X
..
Y
..
Z
..
(active working plane
X,
Y)
(polar
coordinate
programming
permitted)
not
permitted!
o It is not permitted to change the work area limits (G25/G26) for the E axis TRA.
o
G31
(continuous
E
axis)
is
not
permitted
when
TRA
is
active.
o Scaling (G36) is not possible for the E axis with
TRA
function if it
is
programmed before the
TRA function
in
the part program.
o
G37
(coordinate
rotation)
is
possible
with
TRA.
o
If
mirror-image
(G38)
is
programmed
before
the
TRA
function,
axes
X.
Y
and
Z,
at
maximum,
are
mirror-imaged.
The
E
axis
is
subject
to
the
influence
of
the
TRA
function;
G38
is
not
used
here.
o
Tool
radius
compensations
(G41. G42)
are
permitted.
o
With
active
G90
(absolute
dimension
programming).
the
axis
value
programmed
with
G46
Exx
is
the
angle
between
the
contour
and
E
axis.
Example:
NIl
G90
N12
G46
N13
E40
E 10
(angle
between
contour
and
TRA
=
10°)
(angle
betewen
contour
and
TRA
= 40°)
o
With
active
G91
(incremental
dimension
programming).
the
value
of
the
E
axis
programmed
with
G46
Exx
is
the
angle
by
which
the
E
value
programmed
beforehand
is
changed.
Example:
(programmed angle =
10'
before block
NIl)
NIl
G91
N 12
G46
E40
(attar G91, the angle is
10'
+
40'
=
50')
o Zero shifts (G54 - 59, G60, G160) do not act for the E axis (TRA). The shift remains stored and
acts
in
the
case
of
the
next
interpolation
with
the
E
axis
if
TRA
is
not
active.
Values
can
be
stored
in
the zero shift (NPV) table. Zero shilts can be reset with G53, G67, G167.
