1.4 Terminol ogy Definitions
One- keystroke height calibration: In capacitance height measurement
mode, the specific inductive capacity between the capacitance
detect
ion ring and work piece may af fect the accuracy of height
measurement due to t emperature, pressure, humidity, gas composition
and many other ambient factors. In a ddition, the serious non-linear
relationship exists between capacitance value and height value.
Microstep
has developed the int elligent progra m of "one-keystroke
height calibrat
ion". Only one keystoke will aut omatically set the
product based on various ambient factors. And within the range of
3-30mm, high accuracy, high precision and high linearity is possible in
display and control.
High speed zone: When the difference between the actual height and the set
height is relatively big, the cutting head will advance towards the set value at the
highest speed in order to reach the set value the soonest; this travel zone is called
high speed zone.
Speed regulating zone: If the cutting head reaches the set value at a
high speed, severe oscillation may be caused and the height control is
unstable. In order to achieve a smoot h transition, the speed regulating
zone is set. This zone is located between the high-speed zone and the
dead zone. In this zone, when it is far away f rom t he set value, the
cutting head will move at a higher speed; otherwise, at a lower speed.
The range value of this zone is adjust able. If it is set too big, the
transit ion is smooth, but the t racking time is too long; if it is set too
small, the tracking is conducted in time, but oscillation may be caused
easy.
