Examples:
_KNAME="CONTOUR_1"
The milling contour is the complete
program CONTOUR_1.
_KNAME="PIECE245:PIECE245E"
The milling contour is defined as a
section in the calling program, which
starts from the block containing label
PIECE245 to the block 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
contour.
_VARI (machining type)
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.
