MULTIPLE MACHINING
G163. Multiple machining in a full circle

Thus, programming "P7" means that no machining operation takes
place at point 7. Programming "Q10.013" means that no machining
takes place at points 10, 11, 12 and 13.
When defining a set of points (Q10.013), bear in mind that the last
point must be defined with three digits because, for example,
"Q10.13" is the same as programming "Q10.130".
The programming order for these parameters is "P" "Q" "R" "S" "T" "U"
"V" and the numbering sequence for the points assigned to them must
also be respected; In other words, the numbering sequence of the
points assigned to "Q" must be greater than the one of those assigned
to "P" and smaller than the one for those assigned to "R".
Basic operation
Multiple machining is executed as follows:
1. The multiple machining calculates the next programmed point to
machine.
2. Movement to that point at the feedrate programmed with "C" (G00,
G01, G02 or G03).
3. The multiple machining will execute the selected canned cycle
after the movement.
4. The CNC will repeat steps 1-2-3 until completing the programmed
multiple machining operation.
After completing the multiple machining, the tool will remain
positioned at the last point of the programmed path where the
machining operation took place.
P,Q,R,S,T,U,V These parameters are optional and are used to
indicate at which points or between which points of
the ones programmed the machining operation will
NOT be carried out.
Example:
Correct programming P5.006 Q12.015 R20.022
Wrong programming P5.006 Q20.022 R12.015
If these parameters are not programmed, the CNC executes the
machining operation at all the points of the programmed path.
