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 :
