Example of outer-surface machining
Motion of the tool in the cutting direction on the blank element portion
When the tool advances in the cutting direction, the excessive amount
of travel of the tool is as describe below.
When bit 0 of parameter No. 27120 is set to 0, and the tool advances
in the cutting direction, the excessive amount of travel of the tool is
nose radius R if the attribute of the figure across which the tool moves
is the blank element. In this case, the excessive amount of travel is
the distance from the end point of the part figure.

R
When bit 0 of parameter No. 27120 is set to 1, and the tool advances
in the cutting direction, the excessive amount of travel of the tool is
[clearance + 2 × nose radius R] if the attribute of the figure across
which the tool moves is the blank element. In this case, the
excessive amount of travel is the distance from the blank element.
