SIEMENS SINUMERIK BORE 3 - CYCLE 87

                                    The tool drills at the programmed spindle speed and feedrate to the entered final drilling depth.
                During boring 3, a spindle stop without orientation M5 is generated after reaching the final
drilling depth, followed by a programmed stop M0. Pressing the NC START key continues
the retraction movement at rapid traverse until the retraction plane is reached.

                                                                                                                                                                              CYCLE 87( RTP , RFP ,SDIS , DP, DPR, SDIR )

           Where , RTP - Retraction plane

                         RFP- Reference plane

                         SDIS- Safety clearance

                         DP- Final drilling depth

                         DPR- Final drilling depth relative to referance plane

                         SDIR- Direction of rotation M03 OR M04
