Canned cycles (·M· model)
Z Reference plane.
In G90, coordinate referred to part zero.
In G91, coordinate referred to starting plane (Zi).
If not programmed, it assumes as reference plane the current position of the tool (Z=Zi).
I Drilling depth.
In G90, coordinate referred to part zero.
In G91, coordinate referred to reference plane (Z).
D Distance between the reference plane and the part surface.
If not programmed, it assumes a value of 0.
B Drilling peck (step).
All the pecks have this value, except the last one that is adjusted to
the total depth.
H Distance or coordinate it returns to, in rapid (G0), after each drilling
step.
"J" other than 0 means the distance and "J=0" indicates the relief
coordinate or absolute coordinate it withdraws to.
If not programmed, it returns to the reference plane.
C Approach coordinate.
It defines the rapid approach (G0) distance of the longitudinal axis
from the previous drilling peck to carry out a new drilling peck.
If not programmed, it assumes 1 mm.
It issues an error message if "C=0" is programmed.
J It defines after how many drilling pecks the tool returns in rapid (G0) to the reference plane (Z).
With "J" greater than 1, after each peck, the tool returns the distance indicated by "H" and every
"J" pecks to the reference plane (Z).
With "J=1", it returns to the reference plane (Z) after each peck.
If "J" is not programmed or "J=0" is programmed, it returns to the relief coordinate indicated
by "H" after each peck.
