Bolt Hole Circle
Function description:
SW4000 series DRO has the function of BOLT HOLE CIRCLE (BHC) .This function can simplify
the pressing of multiple holes which are attributed equally around the circumference of a circle. The DRO
will guide operator to enter the following parameters:
RADIUS Radius of circle
ST.ANGLE Starting angle that the center of the first
hole on the circle
END.ANGLE Ending angle that the center of the last hole
on the circle
HOLE NUM Hole number
DIRECT Angle direction.
Angle has two directions: counterclockwise and
clockwise. “0” indicates that it is counterclockwise
from ST.ANGLE to END.ANGLE; “1” indicates it is
clockwise from ST.ANGLE to END.ANGLE. As the
following figure, the ST.ANGLE is 0º, END.ANG is
240º. The figure (B) illustrates the arc while angle
direction is counterclockwise; figure (C) illustrates the arc while angle direction is clockwise.
As figure (D) illustrates, machine a hole every 45 deg from
0º ~ 225º. Parameters are as the following:
RADIUS 20
ST.ANGLE 45
END.ANGLE 225
HOL NUM 5
DIRECT 0
NOTE: If ST.ANGLE equals END.ANGLE, the holes are attributed equally around the whole circumference.
The positions of the hole center are calculated automatically after input all parameters. Press
or
to choose the hole No. and move the machine table until the “0.000” appears in X window, Y
