Transformations
6.8 Kinematic transformation
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
-
-
• 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.

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.

Syntax
G07
G05
The commands G07/G05 are used to make it easier to program the inclined axes. Positions
can be programmed and displayed in the Cartesian coordinate system. Tool compensation
and zero offset are included in Cartesian coordinates. After the angle for the inclined axis is
programmed in the NC program, the starting position can be approached (G07) and then the
oblique plunge-cutting (G05) performed.
