File containing basic volumetric compensation data.

The data to be compensated must be a text file (in csv format). The OEM or the company
responsible for the calibration must generate this file and define it in the machine parameter
VCOMPFILE. The units in the file data (millimeters or inches) must be those defined by the
CNC (parameter INCHES).
This file defines the error to be compensated at each volume point. At the intermediate points,
the CNC interpolates the error based on the eight adjacent known points. For the points
outside the defined volume, the error to be compensated will be zero.
Format of the data file.
The text file consists of three data columns and as many rows are there are points to be
compensated, in which the data for each row are separated by the character "," (a comma).
Number of rows = NPOINTSAX1 × NPOINTSAX2 × NPOINTSAX3
Example.
NPOINTSAX1=3
NPOINTSAX2=2
NPOINTSAX3=2
Number of rows on the table or points to be compensated.
NPOINTSAX1 × NPOINTSAX2 × NPOINTSAX3 = 3 × 2 × 2 = 12
• The columns correspond to the axes defined in the parameters VCOMPAXIS1 (first
column), VCOMPAXIS2 (second column) and VCOMPAXIS3 (third column).
• The rows are created with the consecutive error measurements, according to the order
of the axes defined in MOVAXIS; first all the measurements on the first axis; then for each
position on the second axis, all the measurements on the first axis once again; and for
each position on the third axis, all the measurements of the first axis on each position
of the second axis.
