Siemens sinumerik CYCLE 86 " Bore 2" program example

          

                                   Sinumerik CYCLE86 used for "Bore 2" . In this cycle SPOS command used for activated oriented spindle stop , once the drilling depth has been reached. Then the programmed retraction positions are approached in rapid traverse and , from there, the retraction plane .
          This cycle is used if the spindle to be used for the boring operation is technically able to go into position-controlled spindle operation.

CYCLE 86 ( RTP , RFP , SDIS , DP , DPR , DTB , SDIR , RFA , RPO , RPAP , POSS )

 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

             SDIR - Direction of rotation

             RFA- Retraction path along the abscissa of the active plane (incremental )

             RPO- Retraction path along the  orinate of the active plane (incremental)

             RPAP- Retraction path along the boring axis (incremental)

             POSS- Spindle position for oriented spindle stop in the cycle (in degree)
