Circular path G16 with tangential connection
The tool moves on a circular path, starting tangentially (at 2 ) from a
preceding contour element ( 1 to 2 ).
Input:
• Polar coordinate angle H of the arc end point
E
• Polar coordinate radius R of the arc end point E
• The transition points must be defined exactly.
• The POLE is not the center of the contour arc.
Circle with polar coordinates and clockwise rotation.
Enter the distance from the pole to the arc end point, for example
R= 10 mm.
Enter the angle from the angle reference axis to R, for example
H = 80°; terminate the block.
If necessary, enter also:
Radius compensation R
Feed rate F
Miscellaneous function M
Resulting NC block: G16 R+10 H+80 *
