Measurement File Options
Measurement file options are the same for all the
controller types. Reference point is the distance between
machine tool datum and the start point of the
measurement. If measurement file includes several
measurement runs (sets) they all are listed in a
'Measurement set(s)' listbox. It is possible to select
just one or several sets for the compensation. If more
than one set is selected the average of all selected
measurement sets are used for the compensation.
Axes number specifies which axis is to be
compensated. This changes name of a compensation file and
the colum that it affects. If current compensation settings have been
read in earlier, a selection of new axis will change
'Compensation interval' and 'Distance of table from
datum' to active settings.
Compensation interval defines distance between
consecutive compensation points. Interval can only be a
fixed size (2^n / 10000) and thus you have to select a
suitable step from predefined choices. Because amount of
compensation points per table is restricted to 256, it
might be sometimes necessary to increase step size.
Program will inform you if this is necessary.
Distance of table from reference point
This setting determines the start of compensation table
from machine tool datum. If you are creating a new table,
this value can be inverse of 'Distance to reference
point' of measurement (default). However if old
compensations are already active, it might be better to
use old setting.
You can change the name of compensation configuration
file. If old compensation settings have been read in, all
those settings are written to a new file as well.
This is a file where actual compensations of an axis are
written. Notice that in one file there can be many
columns. Each column compensate different axis, just a
row in a file is chosen based on position of the current
axis. CNCcomp compensates only positioning and thus a row
is selected based on location of the same axis as it
Add to existing pitch compensation
If existing pitch compensation file is read from NC, the
new compensation can be actualised cumulative to old
ones. If you want to measure and compensate without
clearing the old compensations, read first the old values to PC,
put a cross in this selection and carry out measurements
so that compensations are set active in a machine tool.
The calculation is done by pressing the CALCULATE
Calculation results are shown on the right side of the
form. The actual compensation file and configuration file
format are shown on the lower right corner of the window.
Saving the compensation parameter file
Compensation parameter file is saved by pressing the
SAVE toolbar button. After this the save file dialog is
opened. It asks for name of compensation file. You should
give equal name to "Compensation file" setting
in screen, but it is not compulsory. Different name just
causes configuration file to have wrong file name entry.
However you have to choice right file extension: .COM or
.VNC The link program you are using might require
specific extension (TNCremo works with both extensions,
but old link programs require .VNC extension).
Program saves without asking also configuration file
into the same directory. It will use file extension .CMA,
if you chose .COM for compensation file. Otherwise
extension will be .SNC A message window will appear on
the screen to tell which file names have been used.
