L5.5
Optional. In the drilling cycle, it defines the minimum drilling peck. It is used with "R" values other
than 1.
If not programmed, a value of 0 is assumed.
R5.5
In the drilling cycle, it indicates the step that reduces the drilling peck "B". If it is not programmed
or is programmed with a value of "0", it assumes a value of "1".
With R =1, all the drilling pecks will be the same (the programmed "B" value).
If R is other than 1, the first drilling peck will be "B", the second one “R B”, The third one “R (RB)”
and so on. In other words, from the second peck on, the new peck will be the product of the R
factor times the previous peck.
In the tapping cycle it defines the type of tapping to be done. If not programmed, it takes the value
of "0", regular tapping.
With R0, regular tapping.
With R1, rigid tapping. The CNC stops the tool with M19 and orients it to begin tapping.
With R2, rigid tapping. If the tool is turning in M3 or M4, the CNC does not stop it nor orient it
to begin tapping. This option does not allow thread repair, even if the part has not been released
because the thread start (entry) will coincide with the one machined earlier.
In order to execute a rigid tapping, the relevant spindle (main or secondary) must be ready to operate
in closed loop. In other words, that it must have a servo drive-motor system with rotary encoder.
