III Functional Specifications
(3) Arc (G36)
The tool starts at the point forming angle θ with the X axis on the circumference of a circle with
radius "r" whose center is the coordinates designated by X and Y, and it drills "n" number of holes
aligned at angle interval △ θ. As with the bolt hole circle function, the drilling operation at each of
the hole positions is based on a hold drilling fixed cycle and so there is a need to retain the drilling
data beforehand.
All movements between the hole positions are conducted in the G00 mode. The data is not retained
upon completion of the G36 command.
G36 Xx Yy Ir Jθ P △ θ Kn ;
Xx,Yy : Center coordinates of arc; they are affected by the G90/G91 commands.
Ir : Radius "r" of arc; it is based on the least command increment and is provided with a positive number.
: Angle θ at the point to be drilled initially; the counterclockwise direction is taken to be positive.
Jθ
P △ θ : Angle interval △ θ; when it is positive, the tool drills in the counterclockwise direction and when it is negative, it drills
in the clockwise direction.
Kn : Number "n" of holes to be drilled; any number of holes from 1 through 9999 can be assigned.
