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
|
|
G55 Mode exposition photo
|
|
G56 plot symbole reference par Dnn A code
|
|
G57 affiche le symbole reference sur la console
|
|
G58 plot et affiche le symbole reference sur la console
|
|
G60 interpolation lineaire ( echelle 100x )
|
|
G70 Unites = Inches
|
|
G71 Unites = Millimetres
|
|
G74 supprime interpolation circulaire sur 360 degre, revient a G01
|
|
G75 Active interpolation circulaire sur 360 degre
|
|
G90 Mode Coordonnees absolues
|
|
G91 Mode Coordonnees Relatives
|
|
|
|
Coordonnees X,Y
|
|
X,Y sont suivies de + ou - et de m+n chiffres (non separes)
|
|
m = partie entiere
|
|
n = partie apres la virgule
|
|
formats classiques : m = 2, n = 3 (format 2.3)
|
|
m = 3, n = 4 (format 3.4)

|
|
G__ X00345Y-06123 D__*

|
1 a 999
|
|
D_CODES:
|
|
|
|
D01 ... D9 = codes d'action:
|
|
D01 = activation de lumiere (baisser de plume) lors du déplacement
|
|
D02 = extinction de lumiere (lever de plume) lors du déplacement
|
|
D03 = Flash
|
|
D09 = VAPE Flash
|
|
D51 = precede par G54 -> Select VAPE
|
|
|
|
D10 ... D255 = Indentification d'outils ( d'ouvertures )

ex: 0.012, 0.012, L , D10
|
|
|
|
Classe les caract en buf_tmp sous forme de tableau de structures D_CODE.
