9.5.3 Tangential control
Function
The rotary tool axes on punching/nibbling machines are aligned tangentially to the
programmed path of the master axes by means of the "Tangential control" function.
Activation
The "Tangential control" function is activated and deactivated with language commands
TANGON and TANGOF respectively.

Programming Manual, Production Planning
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
TANGON.
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.
