Hole patterns in programs
The information for hole patterns can also be written to a program.
Each piece of information is then stored in a separate program
block. These blocks are identified by
CYCL
after the block
number, followed by a number.
The cycles contain all information required by POSITIP for machin-
ing a hole pattern.
There are three cycles for hole patterns:
• CYCL 1.0 FULL CIRCLE
• CYCL 2.0 CIRCLE SEGMENT
• CYCL 4.0 LINEAR HOLE PATTN
Do not delete any blocks from the cycle because this will result in
the error message
CYCLE INCOMPLETE
when the program is
executed.
Hole pattern graphics
The hole patterns in a program can be displayed graphically.
Programming example: Bolt hole circle (full circle)
Number of holes 8
Coordinates of center X = 50 mm
Y = 50 mm
Bolt circle radius 20 mm
Starting angle between
X axis and first hole 30°
Hole depth Z = –5 mm
