5. The pattern can be made up of straight lines and arcs. All the blocks of pattern
definition will be programmed with cartesian coordinates being mandatory to
program the two axes in absolute, otherwise, the CRT will display error 21. If arcs
are included in the definition, they must be programmed with the center’s I,K
coordinates, referred to the arc’s starting point and with the relevant sign. If
functions F,S,T or M are programmed in the definition, they will be ignored except
for the finishing pass. No polar definitions can be programmed.
6. The cycle is completed on the starting position of the tool (0).
7. If the last movement prior to calling the canned cycle (G69) has been executed in
G00, tool radius compensation (G41,G42) can be used. Otherwise error 35 will be
displayed.
The figure shows the elemental cycle. The movements 1->2 and 2->3 will be performed
at the programmed feedrate and the 0->1 and 3->0 in rapid.
