DRO MODE OF OPERATION 15
4.3 TOOL COMPENSATION
With the VNP400 it is possible to work with tool compensation in any operating mode
(DRO mode or program execution mode).
This compensation is applied at all times and it will be present when displaying either
absolute or incremental position values.
This way, it is possible to program directly the profile of the part regardless of the
dimensions of the tool to be used.
To use this feature, it is necessary to indicate to the DRO the dimensions of the selected
tools. These dimensions must be entered in the “RADIUS” and “LENGTH” fields of
the tool table corresponding to each tool.
Tool compensation will only be applied on to the selected axes according to the
indicated field (RADIUS or LENGTH) and with the corresponding sign.
In the case of a Lathe, the Length and Radius fields of the tool table will indicate the
two length dimensions of the tool.
The DRO will display next to the axis position value the “TL+” or “TL-” indicator
when the axis is working with tool length compensation and the “TR+” or “TR-”
indicator when working with toll radius compensation.
Every time a new tool is selected, the DRO will apply the tool compensation
corresponding to the new tool.
There is a “fictitious” tool T00 with field values of R0 and L0 used only to cancel the
tool compensation of all axes at once.
