9.2.11 Circular interpolation control with designated radius
After operated by starting command (
「
indirect start
」
,
「
Simultaneous Start
」
), it operates interpolation
along the trace of the circle made by the specified radius.
Circular interpolation over 360 degrees is available according to
「
Circular interpolation turns
」
.
There is no limit to the composition of 2 axes. User can select 2 axes among 1~ 8-axis randomly.
(1) Radius specified Circular interpolation, absolute coordinate (
「
Absolute, Circular interpolation
」
)
(a) Starts operating at starting position and execute circular interpolation along the trace of the circle which has
radius specified by auxiliary point of main-axis operation data. Center point of Circular arc depends on the
turning direction (CW, CCW) of
「
Circular interpolation mode
」
and size setting of circular arc (Circular
arc<180°, Circular arc>=180°).
Circular interpolation mode Description
Radius, CW, Arc<180° Executes circular interpolation in clockwise and the arc is smaller than 180°
Radius, CW, Arc>=180° Executes circular interpolation in clockwise and the arc is bigger than 180°
Radius, CCW, Arc<180°
Executes circular interpolation in counterclockwise and the arc is smaller than
180° or same.
Radius, CCW, Arc>=180°
Executes circular interpolation in counterclockwise and the arc is bigger than
180° or same.
