7.4 Canned Cycles
The canned cycles described in the table below are implemented in PathPilot.
Canned Cycle Description
G80 Cancel acve canned cycle
G81 Simple drilling cycle
G82 Simple drilling with dwell cycle
G83 Peck drilling cycle
G73 High speed peck drilling cycle
G84 Tapping cycle
G85 Boring cycle – feedrate out
G86 Boring cycle – stop, rapid out
G88 Boring cycle – stop, manual out
G89 Boring cycle – dwell, feedrate out
All canned cycles are performed with respect to the acve plane. The descripons in this secon assume
the XY-plane has been selected. The behavior is always analogous if the YZ or XZ-plane is selected.
Word Definition
X~ X-axis coordinate
Y~ Y-axis coordinate
Z~ Z-axis coordinate
A~ A-axis coordinate
R~
Retract posion along the axis perpendicular to the currently selected plane (Z-axis for XY-
plane, X-axis for YZ-plane, Y-axis for XZ-plane)
L~
L number is oponal and represents the number of repeats
All canned cycles use X, Y, Z, and R words. The R word sets the retract posion; this is along the axis
perpendicular to the currently selected plane (Z-axis for XY-plane, X-axis for YZ-plane, Y-axis for XZ-
plane). Some canned cycles use addional arguments.
Rotaonal axis (A-axis) words are allowed in canned cycles, but it is beer to omit them. If rotaonal
axis words are used, the numbers must be the same as the current posion numbers so that the
rotaonal axes do not move.
The R number is always scky. Scky numbers keep their value on subsequent blocks if they are not
explicitly programmed to be dierent.
