SIEMENS SINUMERIK CYCLE 801 Dot matrix

           Sinumerik CYCLE 801 can be utilized to machine a "matrix gaps" drilling example. The kind of drill gap is controlled by the drilling cycle that has just been called modally.

CYCLE801 ( SPCA , SPCO ,sTA , DIS1 , DIS2 , NUM1 , NUM2 )

      

         Where SPCA =  Reference point of a grid of hole in the abscissa (x-axis)

                    SPCO =  Reference point of a grid of hole in the ordinate (y-axis)

                    STA = Angle to abscissa (x-axis)

                    DIS1= Distance between columns

                    DIS2 = Distance between row 

                    NUM1 = Number of column

                    NUM2 = Number of rows

Example :- Without angle STA=0

Dot matrix consists of 16 holes in 4 rows and 4 columns. And we call  CYCLE 81 for drilling with CYCLE 801 DOT MATRIX . A depth of drill is 30 mm.
