The symbols used above have the following meanings:
fa: Value of "FEED-RATE FOR APPROACHING START POINT"
in the measurement condition of the group number specified in
"MEASUREMENT COND."
Rapid traverse rate when bit 2 (RPDF) of parameter No. 12380
is set to 1.
fb: Value of "FEED-RATE FOR APPROACHING START POINT"
in the axis direction in the measurement condition of the group
number specified in "MEASUREMENT COND."
f: Value of “FEED-RATE FOR 1ST MEASUREMENT" in the
measurement condition of the group number specified in
"MEASUREMENT COND."
α: Value of “APPROACH DISTANCE 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."
ε: Value of "ESCAPING DISTANCE FOR 2ND
MEASUREMENT" in the measurement condition of the group
number specified in "MEASUREMENT COND."
r: Value obtained by dividing ("STYLUS BALL 1ST AXIS
DIAMETER" in the calibration data of the group number
specified in "MEASUREMENT COND.") by 2
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:
G2144 Q D
H V L R F P M W I J S Y
U A B K E ;
Measurement result
When G2144 is executed, the size of the circle is found from the
measured value, and the compensation value obtained from the
difference is output to macro variables for the result of measurement
and as a specified tool offset value.
