Measurement motion
Measurement motion is described below.
<1> A rapid movement is made from the current position to the point
specified by "MEASURE POINT X" and "MEASURE POINT
Y".
<2> In the Z-axis direction, a rapid movement is made to the
approach point (Z coordinate).
Here, the approach point (Z coordinate) represents ("MEASURE
POINT Z" - "APROCH DISTANCE") when the measurement
direction is "+Z", or the approach point (Z coordinate) represents
("MEASURE POINT Z" + "APROCH DISTANCE") when the
measurement direction is "-Z".
<3> In the range from the approach point to ("APROCH
DISTANCE" + γ), a measurement is made at feedrate f. (First
measurement)
<4> Next, a rapid return movement is made to the position (first
measurement point + β), and a measurement is made in the range
from that position to (first measurement point - γ) at the
specified feedrate F. (Second measurement)
The symbols used above have the following meanings:
f: Value of “FEED-RATE FOR 1ST MEASUREMENT" in the
measurement condition of the group number specified in
"MEASUREMENT COND.
β: Value of "ESCAPING DISTANCE FOR 1ST
MEASUREMENT" in the measurement condition of the group
number specified in "MEASUREMENT COND."
γ: Value of "OVERLAP DISTANCE FOR MEASUREMENT" in
the measurement condition of the group number specified in
"MEASUREMENT COND."
G code format
When you press the INSERT key after entering necessary data, a G
code program in the following format is stored in the machining
program memory:
G2022 Q
P H V L R F W I S Y U J K E ;
Measurement result
When G2022 is executed, the result of measurement is output to
macro variables for the result of measurement and as the Z coordinate
of a specified workpiece origin offset value.
