Relation to Conventional Function
This function is available with Parameter No.27220#5=1. This function is
unavailable when a parameter No.27222#7= 1. When parameter
No.27220#5=0, slat Angle cannot be set as conventional version.
Measurement Operation
<1> Operate measurement perpendicular direction to angle entered from a
current point. At 1
st
point measurement, +X axis direction is set to 0°,
and operate to direction of smaller angle. Move to “center point ”
+(“protrude width” /2+α+r) of right angle direction of protrude by rapid
feed rate.
<2> Move to approach point (point of “height of measurement position” +
“approach distance”) for Z axis direction by rapid feed rate.
<3> Move to a point specified at “Height of measurement position” to –Z
axis direction by feed rate Fb, and from that point measure for a range
from approach point to (α+γ-Stylus Radius r ) by federate f. (1
st
measurement)
<4> Then, return for β by rapid federate, and measure for a range from
the returned point to (β+γ) by specified federate at measurement .
(2
nd
measurement)
<5> After that, return forε by rapid feed rate, and return Z axis to
approach point (“height of measurement position” + “Approach
distance”) by Z axis direction.
<6> After that, move to center point by rapid feed rate, and move to an
approach point of minus side by feed rate Fa. Operate the same
measurement to -X(-Y)axis direction.
