14. FUNCTIONS TO SIMPLIFY
G89I ȏ J θ P d Q p ;
This function allows to punch a straight line with length ȏ having angle
θ to X-axis with the current tool position or the position designated by
G72 as a starting point, at pitch P, using a tool with diameter d.
ȏ : Straight line length
The unit is input unit. When a negative number is designated, the
angle θ to a straight line and the +X axis is θ + 180 degrees.
θ : Angle of straight line to the +X-axis
Designate the counterclockwise direction at positive in increments
of input unit (deg).
d : Tool diameter
The unit is input unit.
The tool is offset by d/2 to the left when positive and to the right
when negative from the straight line start point to the end point for
Perform punching operation on the straight line at 0.
p : Pitch
The unit is input unit. Designate the pitch with the length in the
straight line direction.
Cut at angle (G89) is the same as with straight line nibbling (G69) except
that there is no pitch limit value by parameter setting (No. 468 and 469)
and it stops at each punching point for a single block; therefore, refer to
9.3.2 “Straight Line Nibbling (G69)” as well.
