M1: Kinematic transformation
7.10 Examples
Parts program (extracts)
Example of an NC program which uses the set transformations:
; Call single transformations
$TC_DP1[1,1] = 120
$TC_DP3[1,1] = 10
n2 x0 y0 z0 a0 b0 f20000 t1 d1n4 x20
n30 TRANSMIT
n40 x0 y20
n50 x-20 y0
n60 x0 y-20
n70 x20 y0
n80 TRAFOOF
n130 TRACYL(45.)
n140 x0 y0 z20
n150 x-20 z0
n160 x0 z-20
n170 x20 z0
Note
The above examples assume that the angle of the "inclined axis" can be set on the machine
and is set to 0° when the single transformation is activated.

; Switch off TRANSMIT
; Activate inclined axis transformation, parameter: Angle 45°
; 1st of the 2 chained transformations to be switched on
; The previously active transformation TRAANG is
automatically deselected
; The parameter for the inclined axis is 45°
; Activate 2nd chained transformation
; The parameter for the inclined axis is 40°
