5.3 Tool Compensation
The TNC adjusts the spindle path in the tool axis by the
compensation value for the tool length. In the working plane, it
compensates the tool radius.
If you are writing the part program directly on the TNC, the tool
radius compensation is effective only in the working plane. The TNC
accounts for the compensation value in up to five axes including
the rotary axes.
If a part program generated by a CAD system contains
surface-normal vectors, the TNC can perform three-
dimensional tool compensation. For more information,
refer to section 5.4 “Three-Dimensional Tool
Compensation.”
Tool length compensation
Length compensation becomes effective automatically as soon as a
tool is called and the tool axis moves. To cancel length
compensation call a tool with the length L=0.
If you cancel a positive length compensation with TOOL
CALL 0, the distance between tool and workpiece will
be reduced.
After TOOL CALL, the path of the tool in the tool axis, as
entered in the part program, is adjusted by the difference
between the length of the previous tool and that of the
new one.
For tool length compensation, the TNC takes the delta values from
both the TOOL CALL block and the tool table into account:
Compensation value = L + DL
TOOL CALL
+ DL
TAB
, where
L
is the tool length L from the TOOL DEF block or
tool table
DL
TOOL CALL
is the oversize for length DL in the TOOL CALL block
(not taken into account by the position display)
DL
TAB
is the oversize for length DL in the tool table
