Chapter 9 NC Control Function
The parameters related to the circular interpolation are as follows.
Group name and parameter name
4) Helical interpolation (G02/G03)
(G90, G91) G17 (G02, G03) X_ Y_ (I_ J_, R_) Z_ F_
(G90, G91) G18 (G02, G03) X_ Z_ (I_ K_, R_) Y_ F_
(G90, G91) G19 (G02, G03) Y_ Z_ (J_ K_, R_) X_ F
G90, G91: Absolute/Incremental command
G17, G18, G19: Specify the plane to execute the circular interpolation
G02, G03: Clockwise, counter clockwise circular interpolation
X_ Y_ Z_: Target position to traverse
I_ J_ K_/R_: Reference point or radius of an arc
F_: Feed rate
The helical interpolation instructs another axis whose plane is not specified in the circular interpolation command,
and the axis is synchronized in a straight line and traverses with the progress of the circular interpolation. That is,
when XY plane G17 is commanded, the Z axis can be transferred.
