3.11.1 Involute Interpolation with a Linear Axis and Rotation Axis
(G02.2,G03.3)
In the polar coordinate interpolation mode, an involute curve can be
machined using involute interpolation. The involute curve to be
machined is drawn in the plane of the linear axis and rotation axis.
Format
When the linear axis is the X-axis or an axis parallel
to the X-axis
G02.2
X_ C_ I_ J_ R_ F_ ;
G03.2
When the linear axis is the Y-axis or an axis parallel
to the Y-axis
G02.2
Y_ C_ J_ K_ R_ F_ ;
G03.2
When the linear axis is the Z-axis or an axis parallel
to the Z-axis
G02.2
Z_ C_ K_ I_ R_ F_ ;
G03.2
G02.2 : Clockwise involute interpolation
G03.2 : Counterclockwise involute interpolation
Example)When the linear axis is the X-axis
X,C : End point linear axis coordinate of the involute
curve, rotation axis
I,J : Center position of the base circle of the involute
curve viewed from the start point
R : Radius of the base circle
F : Cutting feedrate
