8.1 Tangential control (TANG, TANGON, TANGOF, TLIFT,
Preparatory operation for the definition of tangential tracking:
Activate tangential control for the specified following axis
Deactivate tangential control for the specified following axis
Activate the "Insert intermediate block at contour corners"
function
Delete definition of tangential tracking
Following axis: additional tangential following rotary axis.
Leading axes: path axes, which determine the tangent for the
following axis.
Coupling factor: Relationship between the angular change of the
tangent and the tracked axis
Default: 1
Note:
A coupling factor of 1 does not have to be programmed explicitly.
Identification letter for coordinate system
Basis coordinate system (Default)
"B":
Note:
<CS> = "B" does not have to be explicitly
programmed.
Workpiece coordinate system (not available)
"W":
Optimization
Standard (default)
"S":
Note:
<Opt> = "S" does not have to be explicitly
programmed.
Automatic adaptation of the characteristic over time
"P":
of the tangential axis and the contour
Note:
With <Opt> = "P", the dynamic properties of the
following axis are taken into account in the velocity
limitation of the leading axes. This setting is
especially recommended when using kinematic
transformations.
Offset angle of following axis
Smoothing path of following axis (required for <Opt> = "P")
Angular tolerance of the following axis (optional; only evaluated
for <Opt> = "P")
Note:
Parameters <Dist> and <Angular tolerance> specifically
limit the error between the tracked axis and the tangent of the
leading axes.
