Inclined Y axis (TRAANG)

Function
If your lathe has an inclined Y axis (i.e. this axis is not perpendicular to axes X and Z), you
can still completely program machining operations in Cartesian coordinates. The control
uses the inclined axis function (TRAANG) to transform the Cartesian coordinates to the
motion of the inclined axis.
Setting up
You still have to set up the inclined axis function (TRAANG) via machine data.

Example
For example, for a turning machine with X and Z axes and inclined Y axis, main spindle (C)
and tool spindle (WZ), you must configure the following machine data:
MD20050 $MC_AXCONF_GEOAX_ASSIGN_TAB[ ]
[0] = 1
[1] = 0
[2] = 2
MD20110 $MC_RESET_MODE_MASK
Bit 0 = 1
Bit 7 = 0
MD20112 $MC_START_MODE_MASK
Bit 7 = 1
488
Software option
You require the following software option in order to use the inclined Y axis
function on your machine:
"Inclined axis"
1. real geometry axis X axis.
2. real geometry axis, Y axis not available.
3. real geometry axis, Z axis.
TRAANG is retained after ramp-up.
TRAANG is retained after "Cycle start".
Assignment of geometry axis to channel
axis.
