: 2
nd
measure point X
Input the approximate X coordinate of the second measuring point.
I
: 2
nd
measure point Y
Input the approximate Y coordinate of the second measuring point.
D
: Distance for movement
Input the distance from the measuring start point to the single surface.
J
: Probe axis for movement
Input the probe moving axis and direction (1, 2, 3, 4).
1
: +X,
2
: –X
3
: +Y,
4
: –Y
F
: Feed rate for movement
Input the feed-rate for movement on measuring.
Note ) Please be sure to move the probe to the approximate measuring start point
before executing this cycle.
Movements
:
1. The probe moves to the measuring start point.
2. Moving the distance (D -
α
- stylus radius) with feed-rate (fa).
3. Moving within the distance (D +
γ
- stylus radius) with the feed-rate (f) until touching the
work-piece.
→
First measurement
4. Return the distance (
ε
) with rapid traverse.
5. Moving within the distance (
β
+
γ
) with the feed-rate (f) until touching the work-piece.
→
Second measurement
6. Repeat steps 1. to 5. in the second measuring point.
When
G191
is executed, the system will calculate the angle of X axis from measurement
position and output it to the following variables.
#250
: Angle between X-axis and work-piece
