the first cycle A B C D A
N0030 Z35
；
tool infeed 5mm, the 2
nd
cycle A B1 C1 D A
N0040 Z33.5
；

Example 2:
Fig. 19 b, feed R=-5 mm once, feedrate=100 mm/min and its programming as follows ：
N0010 G00 X55 Z5
；
rapidly position to A point
N0020 G94 X30 Z-5 R-5 F100 ； the first cycle A B1 C D A
N0030 G94 X30 Z-5 R-10 ; tool infeed 5mm, the 2
nd
cycle A B2 C D A
N0040 G94 X30 Z-5 R-15 ; tool infeed 5mm, the 3
rd
cycle A B3 C D A
N0050 G94 X30 Z-5 R-20
；
tool infeed 5mm, the 4
th
cycle A B4 C D A
N0060 G94 X30 Z-5 R-25
；
tool infeed 5mm, the 5
th
cycle A B C D A
Note 1:
In G94 cycle, X, Z, R are not omitted when there is taper, otherwise there is mistake in
dimension.
Note 2:
The computation method of max. taper R( as Fig. 19 b):
Δ CGF Δ CBE GF:BE=CF:CE |GF|=20,|CF|=20(diameter value),|CE|=25 ∵ ∽ ∴
（ diameter value ） , so |R|=|BE|=25.
The direction is negative from C to B in Z ∵ ， so R<0 ， R= ∴ -25.
Note 3:
Other cautions are the same those of G90.
Relationships between the data behind U, W, R and the tool path are as follows:
A(62,45)
(1)U<0,W<0,R<0
