ours in the XY plane
Circular arc in XY plane
Select the arc’s direction of rotation.
Enter the arc dimensions and define the transition to the next element.
ICP generates a G172 or G173 in smart.Turn.
Parameters

Pi Incremental polar target point (distance from starting point
to target point)
W Polar target point (angle)
Wi Incremental polar target point and angle (relative to the
starting point)
I, J Center of arc
Ii, Ji: Incremental center of arc (distance from starting point to
center in X, Z)
PM Polar center of arc
PMi Incremental polar center (distance from starting point to
center)
WM Polar center of arc (angle)
WMi Incremental polar center and angle (relative to the starting
point)
R Radius
ANs Tangential angle in the starting point
ANe Tangential angle in the target point
ANp Angle to the previous element
ANn Angle to the subsequent element
