Example: Enter data and execute a circle pattern. See Fig. I.18 &
Fig. I.19.
Holes (no. of): 4
Coordinates of center: X = 2.0” / Y = 1.5”
Bolt circle radius: 5
S t a r t a n g l e : A n g l e b e t w e e n X a x i s a n d f i r s t h o l e : 2 5 °
Hole depth: Z = -0.25”
1st step: Enter data
Press CIRCLE PATTERN hard key.
Enter the type of circle pattern (full). Cursor to the next field.
Enter the number of holes (4).
Enter the X and Y coordinates of the circle center (X=2.0), (Y=1.5).
Cursor to the next field.
Enter the radius of the circle pattern (5).
Enter the start angle (25°).
Enter the end angle (295°) (this can only be changed if entering a
“segment”). The END ANGLE is defined as the angle from the
positive X-axis to the end of the pattern.
