– Use the following softkey to confirm your input and return to the screen form for this cycle.
● Defining the contour as a section of the called program
KNAME = name of the starting label: name of the end label
Input:
– If the contour is not yet described, specify the name of the starting label and press the following softkey. If the contour
is already described (name of starting label: name of end label), directly press the following softkey:
The control system automatically creates starting and end labels from the name entered and the program jumps to
the contour editor.
– Use the following softkey to confirm your input and return to the screen form for this cycle:
Examples:
The milling contour is the complete pr o-
gram CONTOUR_1.
_KNAME="PIECE245:PIECE245E"
The milling contour is defined as a se c-
tion in the calling program, which starts
from the block containing label PIECE2 45
to the bloc k containing label PIECE245E.
_LP1, _LP2 (length, radius)
Use the parameter _LP1 to program the approach travel or approach radius (distance from the tool external edge to the
contour starting point), and the parameter _LP2 to program the retraction travel or retraction radius (distance from the tool
external edge to the contour end point).
Parameters _LP1 and _LP2 must be set to >0. In the case of zero, error 61116 "Approach or retraction path=0" is output.
Note
When using G40, the approach or retraction travel is the distance from the tool center point to the start or end point of the
Use the parameter _VARI to define the machining type.
If a different value is programmed for the parameter _VARI, the cycle is aborted after output of alarm 61002 "Machining type
defined incorrectly".
_RL (bypassing the contour)
With the parameter _RL, you program the traveling around the contour centrally, to the right or to the left with G40, G41 or
G42.
_AS1, _AS2 (approach direction/path, retraction direction/path)
Use the parameter _AS1 to program the specification of the approach path and _AS2 to program that of the retraction path.
If _AS2 is not programmed, then the behavior of the retraction path is analogous to that of the approach path.
Smooth approach of the contour along a spatial path (helix or straight line) should only be programmed if the tool is not yet
being used or is suitable for this type of approach.
