7.5.5.5 Measurement of a tool length of two tools with the following orientation:
Tool orientation
For tools whose orientation points to the toolholder shows must be set in the system
variables $AC_MEAS_TOOL_MASK, bit 9 = 1 (0x200). The calculated tool lengths are then
included negatively.
Two turning tools each with their own reference point with a tool orientation in the approach direction

Settings in the system data:
Left-hand tool: Approach direction and tool orientation +x
System variable Meaning
$AC_MEAS_TOOL_MASK = 0x2 Tool position in x direction (G19)
$AC_MEAS_DIR_APPROACH = 0 Approach direction +x
Right-hand tool: Approach direction and tool orientation -x
$AC_MEAS_TOOL_MASK = 0x40 Tool position in the -x direction
$AC_MEAS_DIR_APPROACH = 1 Approach direction -x
For both tools
$AC_MEAS_Px_COORD = 1 Coordinate system of x-th measuring point = BCS
$AC_MEAS_SET_COORD = 1 Coordinate system of the setpoint = BCS
