Canned cycles (·M· model)<br />

When selecting the "Y-J" format, bear in mind that the resulting number of machining<br />

operations must be an integer, otherwise, the CNC will issue the relevant error message.<br />

P,Q,R,S,T,U,V These parameters are optional and are used to indicate at which points or between<br />

which points of the ones programmed the machining operation will NOT be carried<br />

out. If these parameters are not programmed, the CNC executes the machining<br />

operation at all the points of the programmed path.<br />

Thus, programming "P7" means that no machining operation takes place at point 7.<br />

Programming "Q10.013" means that no machining takes place at points 10, 11, 12 and<br />

13.<br />

When defining a set of points (Q10.013), bear in mind that the last point must be defined<br />

with three digits because, for example, "Q10.13" is the same as programming "Q10.130".<br />

The programming order for these parameters is "P" "Q" "R" "S" "T" "U" "V" and the<br />

numbering sequence for the points assigned to them must also be respected; In other<br />

words, the numbering sequence of the points assigned to "Q" must be greater than the<br />

one of those assigned to "P" and smaller than the one for those assigned to "R".<br />

Example of proper programming: P5.006 Q12.015 R20.022<br />

Example of wrong programming: P5.006 Q20.022 R12.015<br />

Basic operation<br />

Multiple machining is executed as follows:<br />

1 The multiple machining calculates the next programmed point to machine.<br />

2 Rapid movement (G00) to that point.<br />

3 The multiple machining will execute the selected canned cycle after the movement.<br />

4 The CNC will repeat steps 1-2-3 until completing the programmed multiple machining<br />

operation.<br />

After completing the multiple machining, the tool will remain positioned at the last point<br />

of the programmed path where the machining operation took place.<br />
