21.7 Swiveling
The swivel data set is changed in the CYCLE800 following the CUST_800 jump to the _M40
marker. This means that the variable can also be described in the CUST_800.
Programming example
N10 _TC_CHANGE="HEAD_2"
N20 CYCLE800(0,"HEAD_1",100000,57,0,0,0,0,0,0,0,0,0,-1,100,1)
N30 M0 ;* HEAD_2 is active
N40 _TC_CHANGE="HEAD_3"
N50 CYCLE800(0,"HEAD_1",100000,57,0,0,0,0,0,0,0,0,0,-1,100,1)
N60 M0 ;* HEAD_3 is active
N70 CYCLE800(0,"HEAD_1",100000,57,0,0,0,0,0,0,0,0,0,-1,100,1)
N80 M0 ;* HEAD_1 is active
N90 _TC_CHANGE="TABLE_2"
N100 CYCLE800(0,"TABLE_1",100000,57,0,0,0,0,0,0,0,0,0,-1,100,1)
N110 M0 ;* TABLE_2 is active
N120 M2
Note
The _TC_CHANGE variable must be re-described before each new CYCLE800 call.
Programmed restrictions in the CYCLE800
The swivel data set named in _TC_CHANGE is checked for the following properties:
● The swivel data set to be activated must be enabled.
● The following parameters must match the swivel data set selected on the screen:
– $TC_CARR23 (swivel data set type)
– $TC_CARR37 (swivel mode, units digit)
– $TC_CARR37 (selection of follow-up, ten-thousands digit)
– The mode set (Bit 6, 7) on the screen
21.7.7 CYCLE996 measuring workpiece kinematics
Function
With the Measure kinematics function, it is possible to calculate the geometric vectors used to
define the 5-axis transformation (TRAORI and TCARR) by measuring the position of the ball
in space.
The measurement is essentially carried out by means of workpiece probes, which scan three
positions of a measuring ball on each rotary axis. The ball positions can be defined in
596
(axis-by-axis/solid angle/projection angle/direct) to TC_CARR37
