Supplementary Conditions

Diameter programming active
During incremental traversing and handwheel traversing of the geometry axes of the active
plane, traversing always takes place in the radius programming, even if diameter programming
is active for one of the two involved geometry axes.
Axis is not a geometry axis
Both axes of the active plane must be defined as geometry axes:
● Either by configuration of MD20050 $MC_AXCONF_GEOAX_ASSIGN_TAB
● or by programming GEOAX in the part program
If the axes of the active plane are not defined as geometry axes, then the axes are not traversed
and an alarm is output.
Axis is hirth axis
If an axis involved in the circular path is a hirth axis, then the axis is not traversed and an alarm
is output.
Protection zones
Protection zones are not monitored.

Application example

Initial situation
● The geometry axes are configured as follows:
MD20050 $MC_AXCONF_GEOAX_ASSIGN_TAB[0] = 1
MD20050 $MC_AXCONF_GEOAX_ASSIGN_TAB[1] = 2
MD20050 $MC_AXCONF_GEOAX_ASSIGN_TAB[2] = 3
●
– X axis = 1st geometry axis of active plane
– Y axis = 2nd geometry axis of active plane
● The selected tool has a radius correction value of 0.02 mm.

G17 is active (basic setting):
1st geo. axis = 1st channel axis
2nd geo. axis = 2nd channel ax‐
is
3rd geo. axis = 3rd channel axis
