VOLUMETRIC COMPENSATION.

The CNC can have three types of volumetric compensation: basic, medium or large. The
"Volumetric compensation" software option determines the type of compensation to use. The
CNC can have four volumetric compensations configured, and each may be active
simultaneously. Volumetric compensations are configured in the machine parameters and
are activated from the PLC (marks VOLCOMP1 to VOLCOMP4). The tables that define the
compensation are defined in an external file.
The volumetric compensation includes cross compensation and ballscrew compensation,
and therefore it is not necessary to define the latter two; however, if they are defined, the
CNC takes them into account. The CNC applies the cross compensation and ballscrew
compensation first, followed by the volumetric compensation.
On the gantry axes, compensation is defined for the master axis and the CNC also applies
it to the slave axis.
Basic volumetric compensation.
For basic volumetric compensation, it is necessary to define both axes: the one that moves
and the one that is compensated. This makes it possible to define another type of
compensation that does not involve the same three axes; for example, a common cross
compensation or 2D compensation for the falling ram.
If the CNC has activated either a medium or large volumetric compensation (software
option), it can also allow for a basic volumetric compensation to be defined if the file has an
csv extension. In this case, the CNC will provide the necessary parameters for its definition.
Type. Description.
Basic. • The volume to be compensated is defined by up to 25 points on each axis.
• This compensation corrects translation errors.
• The compensation tables are generated by the calibration application; they
are not editable from the CNC.
• The OEM must define all the compensation data (axes that move, axes to
be compensated, position and size of the volume to be compensated, etc.)
in the machine parameters and select the file containing the compensation
data.
• The basic compensation is the fastest to calibrate, but it can be less precise
than the others (it corrects fewer error components).
Medium.
Large. • Volume compensation of up to 10 m³ (medium) or more than 10 m³ (large).
• This compensation corrects the 21 geometric error components (translation,
rotation and squaring).
• The compensation tables are generated by the calibration application; they
are not editable from the CNC.
• The OEM need only define the axes to be compensated in the machine
parameters and select the file containing the calibration data. The rest of the
data (axes that move, error to be compensated, etc.) are implicit in the file.
• Medium and large compensations are more precise than basic
compensation, but they are slower to calibrate.
