M1: Kinematic transformation
7.3 TRAANG oblique angle transformation (option)
7.3.2.3

Specific settings

Angle between longitudinal axis and inclined axis
● MD24700 $MC_TRAANG_ANGLE_<n> = <angle>
with -90° < angle < 90° , without 0°
The angle is counted positively in the clockwise direction starting at X (see Section "Function
(Page 431)": Angle α).
Base offset of the tool zero
The base offset of the tool zero is specified for the valid geometry axes for the active
transformation. The base offset is included with and without selection of the tool length
compensation. Programmed tool length compensations are added to the base tool.
● $MC_TRAANG_BASE_TOOL_<n>[ k ] = <base offset>
with k = 0, 1, 2 (1st - 3rd geometry axis)
Note
The tool zero is not converted when the angle is changed.
Optimization of velocity control
The machine data used to optimize the velocity control in jog mode and in positioning and
oscillation modes:
Speed margin
The machine data sets the speed margin for the compensation movements of the longitudinal
axis:
MD24720 $MC_TRAANG_PARALLEL_VELO_RES_<n> = <value>
Acceleration margin
The machine data sets the acceleration margin for the compensation movements of the
longitudinal axis:
436
<value> Meaning
0.0 The speed margin is determined by the NC depending on the angle of the inclined
axis and the speed capability of the inclined and the longitudinal axis so that the same
speed limitation results in the direction of the longitudinal axis and of the associated
perpendicular (virtual) axis.
> 0.0 Speed margin = <value> * (MD32000 $MA_MAX_AX_VELO of the longitudinal axis)
