Note
Coupling factor
A coupling factor of 1 does not have to be programmed explicitly.
The direction of the tangential axis is rotated using the coupling factor of -1.
Syntax
TANG(<following axis>, <leading axis_1>, <leading axis_2>, <coupling
factor>, <coordinate system>, <optimization>)
Meaning
TANG(...): Define tangential coupling
<following axis>: Axis name of the following axis (rotary axis)
Data type: AXIS
Range of values: Channel axis names
<leading axis_1>
<leading axis_2>:
Axis names of the leading axes (geometry axes)
1)
Data type: AXIS
Range of values: Geometry axis names of the channel
<coupling factor>: Factor n of the angle change of the following axis for changing the path
tangent of the leading axes:
Angle change
following axis
= angle change
path tangent
* n
Data type: REAL
Default value: 1.0
<coordinate system>: Active coordinate system
2)
Data type: CHAR
Value: "B": Basic coordinate system (default value)
"W": Workpiece coordinate system (not availa‐
ble)
