Arc
Command G2, G3
The arc interpolation effects, that the interpolation point moves from the current
position along the cricular path to the target position. the command G2 effects a
movement in clockwise, the command G3 in counter-clockwise direction.
For the description of a circle in DIN66025 the target coordinates (X/Y/Z) must be
defined. The bending can be defined in two ways: either you enter the radius (R) of the
arc or the center coordinates (I/J/K).
Additional you have the facility to define the circular arc via center coordinates or
aperture angle. Then the target position is set automatically.
Please regard, that not executable requirements (e.g. the radius is shorter than the half
distance between start and target position, or the defined center point has got
different distances to start and target position) effects, that a line is moved instead of
a circle.
