FOR HOLES 1 CYCLE :-
HOLES 1 ( SPCA , SPCO , STA1 , FDIS , DBH , NUM )
Where, SPCA = Abscissa of a reference point on the straight line (X-axis)
SPCO = Ordinate of this reference point (y-axis)
STA1 = Angle to abscissa
Range : -180 < STA1<_ 180
FDIS = Distance from reference point to first hole
DBH = Distance between drilling hole
NUM = No of repeating operation
FOR CYCLE 82 :-
CYCLE82 (RTP , RFP , SDIS , DP , DPR , DTB )
Where, RTP- Retraction plane (absolute)RFP- Reference plane (absolute)
SDIS- Safety distance
DP- Final drilling depth (absolute)
DPR- Final drilling depth related to a reference plane.
DTB- Dwell time at final
EXAMPLE :- Depth of operation is 30 mm
