(3) Line-at-angle Command (G72)
By using the line-at-angle pattern, hole machining positions are defined on the line having an
angle of J from the X-axis. The positions are arranged on this line – L, equally spaced in
intervals of I, and starting from at the point defined by (X, Y).

G code Function
X, Y Used to define the coordinate values of the start point.
The values to be assigned to addresses X and Y should conform to the specified
dimensioning mode, G90 o G91.
I Used to set the interval.
If a negative value is set, positioning is executed in the symmetrical direction in refer-
ence to the start point. The value can be set in units of least input.
J Used to set the angle of the line measured from the X-axis. The value should be set in
units of 0.001 degree and the angle measured in the counterclockwise direction is
expressed by a positive value.
L Used to set the number of positioning times. A positive value must be set.
