3.16 Axis couplings
<following axis>:
Examples
Leading axis change
Before a new tangential coupling can be defined with another leading axis for the following axis,
the existing tangential coupling must first be deleted.
Program code
N10 TANG(A, X, Y, 1)
N20 TANGON(A)
N30 X10 Y20
...
N80 TANGOF(A)
N90 TANGDEL(A)
...
N120 TANG(A, X, Z)
N130 TANGON(A)
...
Geometry axis switchover
Before geometry axis switchover can be performed for an existing coupling, the coupling must
first be deleted.
Program code
N10 GEOAX(2,Y1)
N20 TANG(A, X, Y)
N30 TANGON(A, 90)
N40 G2 F8000 X0 Y0 I0 J50
N50 TANGOF(A)
N60 TANGDEL(A)
N70 GEOAX(2, Y2)
N80 TANG(A, X, Y)
N90 TANGON(A, 90)
