11.5 G164. Multiple machining in arc pattern
The programming format for this cycle is:
Parameters "X" and "Y" define the center of the circle, same as "I" and
"J" in circular interpolations (G02, G03).
When defining the machining operation, only one of parameters "I"
and "K" is required. If the angular step is programmed, bear in mind
that the total angular movement must be the programmed angular
distance "B", otherwise, the CNC will issue the relevant error
message.
G164 X Y B I C F P Q R S T U V
K
X Distance from the starting point to the center along the
abscissa axis.
Y Distance from the starting point to the center along the
ordinate axis.
B Angular distance in degrees of the machining path.
I Angular step between machining operations.
When the movement between points is done in G00 or G01,
the sign indicates the direction: "I+" counterclockwise and "I-
" clockwise.
K Total number of machining operations including that of the
machining definition point.
When the movement between points is done in G00 or G01,
the machining operation is carried out counterclockwise.
C It indicates how it will move between the machining points. If
not programmed, a value of C = 0 is assumed.
C=0 In rapid (G00).
C=1 Linear interpolation (G01).
C=2 In clockwise circular interpolation (G02).
C=3 In counterclockwise circular interpolation (G03).
