G02,G20,G21 Interpolation circulaire , sens trigo < 0
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
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)
ex:
G__ X00345Y-06123 D__*
Outils et D_CODES
numero d'outil ( identification des formes )
1 a 99 (classique)
1 a 999
D_CODES:
D01 ... D9 = codes d'action:
D01 = activation de lumiere (baisser de plume) lors du d�placement
D02 = extinction de lumiere (lever de plume) lors du d�placement
D03 = Flash
D09 = VAPE Flash
D10 ... = Indentification d'outils ( d'ouvertures )
