1.3.9 Setting of Torque to Pressure Conversion Data
After the execution of Motor Gun Auto Turning function, by following the
procedure below, re-measure the pressure and reset the torque to
pressure conversion data.
1. Set a value to {THICKNESS FORCE GAUGE} and select “ENABLE” at
{PRESS MEASUREMENT MODE} on MANUAL PRESS window.
2. Set the pressure value to the pressure file.
– As the unit of this pressure, specify torque(%).
– Specify 5(%) to the touch speed of the pressure file.
3. Register SVGUNCL instruction to a JOB.
– Specify the pressure file set at the step 2.
4. Execute the JOB and measure the pressure with the force gauge.
5. Execute the above procedures 2 through 4 with the different torque(%)
to measure a torque(%) for the pressure.
6. Input the acquired data to “Torque to pressure conversion” in the gun
condition file. Up to 12 data can be registered.
On MANUAL PRESS window, set a value to {THICKNESS
FORCE GAUGE} and select “ENABLE” to {PRESS MEA-
SUREMENT MODE}.
The PRESS MEASUREMENT MODE becomes “UNABLE”
in case the mode is changed from the teach mode to the
play mode. Set “ENABLE” again when the mode is
changed.
