Machine manufacturer
The following settings are defined in machine data:
● The angle between a machine axis and the oblique axis,
● The position of the zero point of the tool relative to the origin of the coordinate system
specified by the "inclined axis" function,
● The speed reserve held ready on the parallel axis for the compensating movement,
● The axis acceleration reserve held ready on the parallel axis for the compensating
movement.
Axis configuration
To program in the Cartesian coordinate system, it is necessary to inform the control of the
correlation between this coordinate system and the actually existing machine axes (MU,MZ):
● Assignment of names to geometry axes
● Assignment of geometry axes to channel axes
– general situation (inclined axis not active)
– inclined axis active
● Assignment of channel axes to machine axis numbers
● Identification of spindles
● Allocation of machine axis names.
Apart from "inclined axis active", the procedure corresponds to the procedure for normal axis
configuration.
6.8.4 Inclined axis programming (G05, G07)
Function
In Jog mode, the movement of the grinding wheel can either be cartesian or in the direction
of the inclined axis (the display stays cartesian). All that moves is the real U axis, the Z axis
display is updated.
In jog–mode, REPOS–offsets must be traversed using Cartesian coordinates.
In jog–mode with active "PTP–travel", the Cartesian operating range limit is monitored for
overtravel and the relevant axis is braked beforehand. If "PTP travel" is not active, the axis
can be traversed right up to the operating range limit.
