Fixed Cycles for Turning

Fixed Cycles for Turning
          
                          When performing roughing and other such operations during turning, these functions permit to command in a single block the machining program which is normally commanded in several blocks. In other words, they simplify the machining program. The following types of fixed cycles for turning are available.

G-code:-

          G90    or      G77    = Longitudinal Turning Cycle 
          G92    or      G78    = Threading Cycle
          G94    or      G79    = Transverse Turning Cycle.


Programming Format:-

          G90 X__ Z__ R__ F___ ;

          Or

         G77 X__ Z__ R__ F__ ;

Same for G92, G94

X        =  X cutting point
Z        = Z turning length
R        = Taper Value (Radial)
F        = Feed Rate.
Longitudinal turning cycle G90 or G77:-

1.   Straight turning

2.   Taper turning

Threading cycle G92 or G78

1.   Straight turning  

2.   Taper turning

Transverse turning cycle G94 or G79

1.   Straight turning

2.   Taper turning
