8.2.9 Designate Midpoint of Circular Interpolation
It was progressed by start command of positioning operation (
「
Indirect start
」
,
「
direct start
」
) and operate
interpolation following the path of circular which is through midpoint that is set by 2 axes.
And, Can progress circular interpolation of over 360 degrees by the set number of circular interpolation.
The combination of 2 axes for circular interpolation is unlimited. User can randomly use 2 axes from axis 1 to axis 4.
(1)
Control of circular interpolation by absolute coordinate, designate midpoint(Absolute, circular interpolation)
(a) Operate circular interpolation from starting point and pass the midpoint that is set operation data to target point.
(b) To be made path of circular interpolation with start position, midpoint and a crossing which is perpendicular divide
equally position of midpoint and target position.
(c) Movement direction is decided automatically depends on set target position and auxiliary point of circular
interpolation.

(d) Restriction
■ User can’t draw circle which is starting point same with last point on the circular interpolation of midpoint
designation method. If you want to draw circle, please use method of midpoint.
■ User cannot progress circular interpolation of midpoint designation method with following cases.
