Arc (G36)
G36 X x1 Y y1 I r J θ P ∆θ K n ;
X, Y :Center coordinates of arc. This will be affected by G90/G91.
I :Radius r of arc. The unit follows the input setting unit, and is given with a positive
No.
:Angle θ of the point to be drilled first. The CCW direction is positive. (The decimal
J
point position will be the degree class. If there is no decimal point, the unit will be
0.001 ° .)
:Angle interval ∆θ . When the value is positive, the drilling will take place in the CCW
P
direction, and in the CW direction when negative. (The decimal point position will
be the degree class. If there is no decimal point, the unit will be 0.001 ° .)
K :No. of holes n to be drilled. 1 to 9999 can be designated.
The n holes aligned at the angle interval ∆θ will be drilled starting at point created by the X axis and
angle θ . The circumference is that of the radius R centering on the coordinates designated with XX
and Y. As with the bolt hole circle, the hole drilling operation at each hole will depend on the
standard canned cycle.
The movement between hole positions will all be done in the G00 mode. G36 will not hold the data
even when the command is completed.
