Siemens sinumerik CYCLE 85 " Bore 1" cycle program

                  Sinumerik CYCLE85 is used for " Boring 1" cycle . The inward and outword movement is performed at the feedrate assigned to feedrate and retraction feedrate.

CYCLE85 ( RTP ,RFP , SDIS , DP , DPR , DTB , FFR, RFF )

Where, RTP- Retraction plane (absolute)
             RFP- Reference plane (absolute)

             SDIS- Safety distance 

             DP- Final drilling depth (absolute)

             DPR- Final drilling depth related to reference plane .

             DTB- Dwell time at final
             FFR- Feedrate .
             RFF- Retraction feedrate (1.5 x FFR )
