Measurement of a tool length of two tools with the following orientation:
Two turning tools with:
Their own reference point each for tool orientation in the approach
direction.
One reference point for tool position that is opposite to the approach
direction and tool orientation.
Two milling tools with:
Their own reference point each for tool orientation in -y.
One reference point for tool position in -y and a tool position opposite to
the approach direction.
Two milling tools rotated 90 degrees with:
Their own reference point each for tool orientation in the approach
direction.
One reference point for a tool position that is opposite to the approach
direction and tool orientation.
