Coupled Motion Of Punch And Die - Siemens SINUMERIK 840D sl Function Manual

10.5.2

Coupled motion of punch and die

Function
Using the standard function "Coupled motion", it is possible to assign the axis of the die as a
coupled motion axis to the rotary axis of the punch.
Activation
The "Coupled motion" function is activated or deactivated with language commands
TRAILON and TRAILOF respectively.

Example
Example of a typical nibbling machine with rotatable punches where C is the punch axis and
C1 the die axis:
:
:
TRAILON (C1, C, 1)
G01 X100 Y100 C0 PON
X150 C45
:
:
M30
Basic position
No coupled-motion groupings are active after power up. Once the two tool axes have
approached the reference point, the coupled-motion grouping is not generally separated
again.
This can be achieved by:
● Program single activation of the coupled-motion grouping (see example above)
● Program MD setting:
In this way, the coupled-motion grouping remains active after RESET/part program start or
end.
