SECTION FOUR - PREPARATORY FUNCTIONS (G CODES)
Trig Help will allow the programmer to estimate both the start and end points of any arc. The
control will calculate the true start and end points based on the moves preceding and trailing the
arc. Where there are two possible correct answers, the control will choose the point closest to the
estimated point. If the slope of the line entering or leaving the arc is such that no intersection
occurs, the line will be made tangent to the arc.
Examples of Trig Help follow.
