Grid (G37.1)
G37.1 X x1 Y y1 I Dx P nx J Dy K ny ;
X, Y :Designation of start point coordinates. This will be affected by G90/G91.
I :Interval Dx of the X axis. The unit will follow the input setting unit. If Dx is positive,
the interval will be in the forward direction looking from the start point, and when
negative, will be in the reverse direction looking from the start point.
P :No. of holes nx in the X axis direction. The setting range is 1 to 9999.
J :Interval Dy of the Y axis. The unit will follow the input setting unit. If Dy is positive,
the interval will be in the forward direction looking from the start point, and when
negative, will be in the reverse direction looking from the start point.
K :No. of holes ny in the Y axis direction. The setting range is 1 to 9999.
The nx points on a grid are drilled with an interval ∆ x parallel to the X axis, starting at the position
designated with X, Y. The drilling operation at each hole position will depend on the standard
canned cycle, so the hole drilling data (hole machining mode and hole machining data) must be
held beforehand.
The movement between hole positions will all be done in the G00 mode. G37.1 will not hold the
data even when the command is completed.
