CNC Infomation System: MULTIPLE REPETITIVE CYCLE

MULTIPLE REPETITIVE CYCLE:-

Mazak machine EIA / ISO program

Canned Cycles:-

G70 = Finishing Cycle

G71 = Longitudinal Roughing Cycle

G72 = Transverse Roughing Cycle

G73 = Contour –Parallel Roughing Cycle

G74 = Longitudinal Cut-Off Cycle

G75 = Transverse Cut-Off Cycle

G76 = Compound Threading Cycle

Programming Format:-

Fanuc control has 3 different methods have for G Coding

1. Standard method

2. Special method

3. T32 series method

T32 Series programming format is different for other methods.

We check first standard format:-

STANDARD FORMAT:-

G70 = G70 A__ P__ Q__ ;

G71 = G71 U__ R__ ;

G71 A__ P__ Q__ U__ W__ F__ S__ T__;

G72 = G72 W__ R__ ;

G72 A__ P__ Q__ U__ W__ F__ S__ T__;

G73 = G73 U__ W__ R__ ;

G73 P__ Q __ U__ W__ F__ S__ T__;

G74 = G74 R__ ;

G74 X__Z__ P__ Q__ R__ F__ S__ T__;

G74 = G75 R__ ;

G75 X__Z__ P__ Q__ R__ F__ S__ T__;

G76 = G76 P__ Q __ R__ ;

G76 X__ U__ R__ P__ Q __ F__ ;
