One key height calibration: when the capacitance height measurement is
adopted, the specific inductive capacity between the capacitance detection ring
and the cutting board may affect the accuracy of height measurement due to
temperature, pressure, humidity, gas composition and many other factors on site.
In addition, the serious non-linear relationship exists between capacitance value
and height value. Our company has developed the intelligent program of "a key
height calibration". You only need to press a key on site, you can set various
factors of change automatically. And within 3-30mm, the display and control of
high accuracy, high precision and high linearity are realized.
High speed zone: When the difference between the actual height and the set
height is bigger, in order to reach the set value at the fastest speed, the cutting
head advances for the set value at the highest speed; this zone is called high
speed zone.
Speed Regulating Zone: When the cutting head reaches the set value at high
speed, severe oscillation may be caused so that the height control is unstable. In
order to achieve a smooth transition, the speed regulating zone is set. This zone
is located between the high-speed zone and dead zone. In this zone, when it is
farther away from the set value, the cutting head moves at higher speed; if not,
at a lower speed. The range value in this zone may be set. When it is too big, the
transition is smooth, but the track time is too long; when it is too small, the
tracking is conducted in time, but oscillation may be caused easily.
Dead zone: When the cutting head is within certain height value, the height of
the cutting head will not be adjusted any more. The range is called dead zone.
When the dead-zone value is too large, the control precision is too low; when it is
too small, the cutting head may oscillate up and down easily. The appropriate
value of dead zone not only can guarantee the control precision but also do not
generate oscillation.
