Function Manual, 11/2012, 6FC5397-1CP10-5BA0
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.
Example: Linear interpolation
The punching/nibbling machine has a rotatable punch and die with separate drives.
Programming example:
:
N2 TANG (C, X, Y, 1, "B") ; Define master and slave axes, C is slave axis for X
and Y in the base coordinate system
N5 G0 X10 Y5 ; Start position
N8 TRAILON (C1, C, 1) ; Activate coupled motion of rotatable tool axes C/C1
N10 Y10 C225 PON F60 ; C/C1 axis rotates to 225° ↷ stroke
N15 X20 Y20 C45 ; C/C1 axis rotates to 45° ↷ stroke
N20 X50 Y20 C90 SPOF ; C/C1 axis rotates to 90°, no stroke initiation
N25 X80 Y20 SPP=10 SON ; Path segmentation: four strokes are executed with
tool rotated to 90°
N30 X60 Y40 SPOF ; Position
N32 TANGON (C, 180) ; Activate tangential control, offset angle of
rotatable tool axes 180°
N35 X30 Y70 SPN=3 PON ; Path segmentation, three strokes with active
tangential control and an offset angle of 180°
N40 G91 C45 X-10 Y-10 ; C/C1 rotates to 225° (180° + 45° INC), tangential
control deactivated because no path segmentation
↷ stroke
N42 TANGON (C, 0) ; Tangential control without offset
N45 G90 Y30 SPN=3 SON ; Path segmentation, three strokes with active
tangential control but without offset angle
N50 SPOF TANGOF ; Deactivate stroke init tangential control
