(Note 1) When going around at a narrow angle (there is α < 1˚) no cross point of 2
perpendicular lines from programme lines, so that tool center path will be
exceptionally as follows;
Linear - linear
Linear –Arc
It will be processed in the same procedure as above in case of Arc-Linear and Arc-Arc.
(Note 2) When (180˚
≤ θ< 181˚), tool center path will be as follows;
Linear - linear
It will be processed in the same procedure as above in case of Arc-Linear, Linear-Arc and Arc-
Arc.
