SIEMENS SINUMERIK HOLES 2

 
                  Sinumerik HOLES 2 Cycle is used to machine circle of holes. It means the operation performed in a circle.


HOLES 2 ( CPA , CPO , RAD , STA1 , INDA , NUM )
             
               Where ,  CPA = Centre point of a circle of holes, abscissa.
                              CPO = Centre point of a circle of the hole, an ordinate
                              RAD = Radius of the circle of holes
                              STA1 = Starting angle
                                            Range : -180< STA1<_ 180 degree
                              INDA - Incrementing angle
                              NUM -  No of a drill hole

EXAMPLE : With MCALL drilling cycle CYCLE 81
                
In this program HOLES, 2 cycles are used only for tool travel at operation position & CYCLE 81 is used to performing an operation. A depth of drilling is 30 mm
