Punching and Nibbling (N4)
15.5 Rotatable tool
Mode of operation
The tangential axis is coupled to the interpolation of the master axes. It is therefore not
possible to position the axis at the appropriate punching position tangentially to the path
independently of velocity. This may lead to a reduction in machining velocity if the dynamics
of the rotary axis are unfavorable in relation to those of the master axes. Additional offset
angles can be programmed directly via language command
Note
If the tool (punch and die) is positioned by two separate drives, then the functions
"Tangential control" and "Coupled motion" can be used.
Notice: The "Tangential control" function must be activated first followed by "Coupled
motion".
The tangential control function automatically aligns the punch vertically to the direction vector
of the programmed path. The tangential tool is positioned before the first punching operation
is executed along the programmed path. The tangential angle is always referred to the
positive X axis. A programmed additional angle is added to the calculated angle.
The tangential control function can be used in the linear and circular interpolation modes.
Example: Linear interpolation
The punching/nibbling machine has a rotatable punch and die with separate drives.

; Define master and slave axes, C is slave axis for X
and Y in the base coordinate system
; Start position
; Activate coupled motion of rotatable tool axes C/C1
; C/C1 axis rotates to 225° ↷stroke
; C/C1 axis rotates to 45° ↷stroke
; C/C1 axis rotates to 90°, no stroke initiation
; Path segmentation: four strokes are executed with
tool rotated to 90°
; Position
; Activate tangential control, offset angle of
rotatable tool axes 180°
; Path segmentation, three strokes with active
tangential control and an offset angle of 180°
; C/C1 rotates to 225° (180° + 45° INC), tangential
control deactivated because no path segmentation
↷stroke
; Tangential control without offset
; Path segmentation, three strokes with active
tangential control but without offset angle
; Deactivate stroke initiation + tangential control
