3.4 TOOL
When selecting this option, the CNC allows access to the tool table and it is possible
to calibrate tools.
3.4.1 TOOL TABLE
When selecting this option, the CNC shows the values assigned to each offset; that
is, the dimensions of each tool being used to machine the parts.
Once the tool offset table is selected, the operator may move the cursor one line at
a time by using the up and down arrow keys.
Each tool offset has several fields which define the dimensions of the tool. These
fields are the following:
*
Tool length along the X axis.
It is given in radius and in the units currently selected. Its value range is:
X ±8388.607 mm
*
or
X ±330.2599 inches.
Tool length along the Z axis.
It is given in the units currently selected. Its value range is:
Z ±8388.607 mm
*
or
Z ±330.2599 inches.
Tool radius.
It is given in the units currently selected. Its maximum value is:
R 1000.000 mm
or
R 39.3700 inches.
The CNC will take this "R" value and the type of tool (location code or shape
code "F") when machining the programmed profile. In other words, the CNC
will apply tool compensation in all finishing passes.
*
Tool type.
To indicate the type of tool being used, the CNC offers 10 different location
codes (F0 thru F9).
This factor depends on the shape of the tool being used and on the sides of the
cutter used for machining.
The following drawing shows the tool types commonly used on a lathe indicating
in all of them the center (C) of the cutter and its theoretical tip (P).
