This sample path has the following values:
- Start point : (0,100.0)
- End point (X,Y) : (0,-30.0)
- Distance to the center (I,J) : (0,-100.0)
- Radius increment or decrement (Q) : -20.0
- Number of revolutions (L) : 4
(1) With absolute values, the path is programmed as follows:
G90 G02 X0 Y-30.0 I0 J-100.0 {Q-20.0 or L4} F300 ;
(2) With incremental values, the path is programmed as follows:
G91 G02 X0 Y-30.0 I0 J-100.0{Q-20.0 or L4} F300 ;
(Either the Q or L setting can be omitted.)

The sample path shown above is programmed with absolute and
incremental values as follows:
This sample path has the following values:
- Start point : (0,100.0,0)
- End point (X,Y) : (0,-37.5,62.5)
- Distance to the center (I,J) : (0,-100.0)
- Radius increment or decrement (Q) : -25.0
- Height increment or decrement (K) : 25.0
- Number of revolutions (L) : 3
(1) With absolute values, the path is programmed as follows:
G90 G02 X0 Y-37.5 Z62.5 I0 J-100.0 { K25.0, Q-25.0, or L3}
F300 ;
(2) With incremental values, the path is programmed as follows:
G90 G02 X0 Y-137.5 Z62.5 I0 J-100.0 { K25.0, Q-25.0, or
L3}
F300 ;
