Circular arc in XY plane
Programming a circular arc:
Select the arc's direction of rotation
Enter the arc dimensions
Define the transition to the next contour element
Parameters:
X, Y: Target point
Xi, Yi: Target point (incremental)
P: Target point (in polar coordinates)
Pi: Target point – Distance between starting point and target
point (polar, incremental)
W: Target point (polar angle)
Wi: Target point (polar angle, incremental; reference: starting
point)
I, J: Center point of circular arc
Ii, Ji: Center point of circular arc (incremental) – Distance
between starting point and Center point in X and Y
PM: Center point of circular arc (polar)
PMi: Center point of circular arc – Distance between starting
point and Center point (polar, incremental)
WM: Center point of circular arc (polar angle)
WMi: Center point of circular arc (polar angle, incremental;
reference: starting point)
R: Radius
ANs: Angle – Tangential angle in the starting point
ANe: Angle – Tangential angle in the target point
ANn: Angle to the subsequent element
ANp: Angle to the previous element
F: Further information:
ICP generates a G172 or G173 in smart.Turn mode of operation.
