Example for exercise: Circle center in polar coordinates related to the end point of another
contour element
Known data for CC:
• Cartesian coordinates of FPOL:
X
= 13, Y = 17 mm
• Polar coordinate radius
is 20 mm shorter than the distance from
FPOL to the end point of E1:
IPR =
–20 mm
• Polar coordinate angle is 33° greater than
the corresponding angle for the end point
of E2:
IPA = 33°
Initiate the dialog for FPOL:
Enter the X coordinate of FPOL:
FPOL: COORDINATES ?
Enter the X coordinate, X=13 mm.
Enter the Y coordinate of FPOL:
FPOL: COORDINATES ?
Enter the Y coordinate, Y=17 mm.
Close the block:
Resulting NC block: FPOL X+13 Y+17
