Volumetric and Cross Compensation, Axis Calibration
OPENcontrol CNC can offer even higher working precision for the machine tool, using
the Volumetric Compensation algorithm. This algorithm has been designed to take into
account and correct for any positioning errors, which occur as a result of any mechanical
distortions created by the machine tool in the working volume.
The OPENcontrol Volumetric Compensation algorithm is capable of correcting many
different types of positioning errors in space.
Acquired positioning error data
can be used to correct a single or
multiple errors introduced by the
mechanics. Typical uses would be
bi-directional Axis Calibration,
twist error correction and Cross
Compensation of an axis, non-
orthogonal, etc.
After taking a number of
measurements on the machine
tool, OPENcontrol is able to
compensate the errors by interpolating the available values.
The number of measurements taken will determine the accuracy of the correction which
can be achieved. The greater the number of samples is, the greater will be the accuracy.
This software module is organized with three different optional levels:
Level 1: bi-directional Axis Calibration for a single axis
Level 2: Cross Compensation and compensation of non-orthogonal axes
Level 3: Compensation of all position error types
Higher levels include the features of the previous ones.
