14.1 Automatic tool-length measurement

Automatic tool-length measurement is one of most implemented function, e.g.
because mechanically it is very easy to do. If high measurement accuracy is
required, the sensor must be a good quality. In the CSMIO/IP-M controller –
specialy for G31 command (used while the measurement) – completely
autonomous movement operation and ultra-fast logic were implemented to
assure the measurement precision at the highest level.
The measurement is made through the following stages:
Raising the Z axis at the maximum high (absolute zero)
•
Driving in the fast mode (G0) at the XY sensor position.
•
Quick exit (G0) by Z-axis to the so-called. safe Z
•
Driving down the measurement mode (G31) at "1" speed until receiving the signal from the
•
sensor.
Raising the Z-axis by a small value (preparing to measurement that is more accurate).
•
Driving down the measurement mode (G31) at "2"speed, until receiving a signal from the
•
sensor.
After finished measurement – raising the Z-axis maximally.
