TL_RADIUS ;
Specify tool radius
Explanation: Using the TL_RADIUS[T no., E no.] command, the tool
radii that are required for the enhanced look-ahead func-
tion may centrally be defined at the beginning of the pro-
gram. The compiler employs the current T or E no. if a T
no. or an E no. has not been specified.
Example:
:
N0005 TL_RADIUS[1234567,1]=24.995
N0006 TL_RADIUS[923,3]=20.31
N0007 TL_RADIUS[9,9]=29.89
:
CAUTION
If the tool radius path correction of the enhanced look-
ahead function is employed (TRC <> 0), the tool radius
that, using the pre-defined TL_RADIUS[T no., E no.], has
been specified in the NC program during compilation
must exist during machining.
TRC ;
Tool radius correction
Explanation: TRC=0: The enhanced look-ahead function does not
perform radius correction.
TRC=1: The enhanced look-ahead function performs
radius correction to the left of the contour, us-
ing the tool radius specified under
TL_RADIUS.
TRC=2: The enhanced look-ahead function performs
radius correction to the right of the contour,
using the tool radius specified under
TL_RADIUS.
ADTRC ;
Approach distance for tool radius compensation
Explanation: ADTRC = 0 To set up the tool radius compensation,
the enhanced look-ahead function does
not take any approach or retract distance
into account.
ADTRC 0 If tool radius compensation is activated
with TRC=1 or TRC=2, the enhanced
look-ahead function inserts a straight line
with tangential transition and of the length
that must be specified here before the
first polygon element (first motion block
after LA_ON), and after the last polygon
element (last motion block before
LA_OFF).
Only NC blocks that contain G1, G2, G3 movements, event commands
(SE,RE) velocity specifications (F), acceleration limits (ACC_EFF) and swift
auxiliary function outputs (MQxxx, QQxxxx and Sxxxxx.xx, if S has been
selected as a swift auxiliary function) may occur within the program se-
quence that shall be optimized.
The end points of NC blocks whose velocity profile shall be processed by
the enhanced look-ahead function may not be specified by variables.
