SIEMENS SINUMERIK CYCLE 801 WITH ANGLE TO ABSCISSA ( STA)

                                        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. In this program, we perform an operation with an angle.

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 :- With angle

                 Dot matrix consists of 12 holes in 4 columns & 3 rows with an angle to abscissa (STA). And call CYCLE 81 for drilling with CYCLE 801 dot matrix.
