4-4. Outside circle measurement (G183)
This is a menu for measuring the center position and radius of an outside circle.
Create ISO code program in the following form.
G183 Z R F W ;
Z
: Height for Z axis
Input the height from the measuring start point to the point which will be measured.
R
: Outside radius
Input the approximate radius of the outside circle.
F
: Feed rate for movement
Input the feed-rate for movement on measuring.
W
: Work coordinate system number
Input the work-piece coordinate system number which will be set.

Note ) Please be sure to move the probe right over the approximate center of
outside circle before executing this cycle.
Movements
:
1. The probe moves the distance (R +
α
+ stylus radius) along the X axis with feed-rate
(fa). 2. Moving the distance (Z) along –Z axis with feed-rate (fa).
3. Moving within the distance (R -
γ
+ stylus radius) with the feed-rate (f) until touching the
work-piece.
4. Return the distance (
ε
) with rapid traverse.
