Drilling Cycles and Drilling Patterns
2.3 Drill pattern cycles
2.3.4 Dot matrix – CYCLE801 (SW 5.3 and later)
CYCLE801 (_SPCA, _SPCO, _STA, _DIS1,
_DIS2, _NUM1, _NUM2)
Cycle CYCLE801 can be used to machine a "grid of
holes". The type of hole is determined by the drilling
cycle that has already been called modally.
Sequence of operations
The cycle calculates the sequence of holes such that
the empty paths between them are kept as short as
possible. The starting position of the machining
operation is defined according to the last position
reached in the plane prior to the cycle call.
Starting positions are one of the four possible corner
positions in each case.
