* G03,G30,G31 Interpolation circulaire , sens trigo > 0
|

* G04 commentaire
|

* G06 Interpolation parabolique
|

* G07 Interpolation cubique
|

* G10 interpolation lineaire ( echelle 10x )
|
||
* G11 interpolation lineaire ( echelle 0.1x )
|
||
* G12 interpolation lineaire ( echelle 0.01x )
|
||
* G52 plot symbole reference par Dnn code
|
||
* G53 plot symbole reference par Dnn ; symbole tourne de -90 degres
|
||
* G54 Selection d'outil
