Assignment for all types of transformation
The assignments between the toolholder data for writing the linear offsets and the
corresponding machine data for kinematic transformations are determined by the
transformation type. The following assignment of all other parameters is identical for all three
possible types of transformation:
Assignment for all types of transformation together identical
MD24100 $MC_TRAFO_TYPE_1 (definition of
transformation 1 in the channel)
MD24570 $MC_TRAFO5_AXIS1_1[0] (direction first rotary axis)
MD24570 $MC_TRAFO5_AXIS1_1[1]
MD24570 $MC_TRAFO5_AXIS1_1[2]
MD24572 $MC_TRAFO5_AXIS2_1[0] (direction second rotary
axis)
MD24572 $MC_TRAFO5_AXIS2_1[1]
MD24572 $MC_TRAFO5_AXIS2_1[2]
MD24510 $MC_TRAFO5_ROT_AX_OFFSET_1[0] (position offset
of rotary axes 1/2/3 for 5-axis transformation) 1)
MD24510 $MC_TRAFO5_ROT_AX_OFFSET_1[1]
MD24520 $MC_TRAFO5_ROT_SIGN_IS_PLUS_1[0] (sign of
rotary axis 1/2/3 for 5-axis transformation 1)
MD24520 $MC_TRAFO5_ROT_SIGN_IS_PLUS_1[1]
*) Machine data MD24520/MD24620 $MC_TRAFO5_ROT_SIGN_IS_PLUS_1/2 are
redundant. They are used to invert the direction of rotation of the assigned rotary axis.
However, this can also be achieved by inverting the direction of axis vector
$MC_TRAFO5_AXIS1/2_1/2. It is for this reason that there is no corresponding parameter
for the orientable toolholder. For the purpose of absolute clarity, the following machine data
must be ignored:
