Tool life,
replacement tool
You can enter two tool life values (TIME1 and TIME2) and one replacement
tool (RT) for each tool in the tool table.
TOOL-CALL key:
n
CUR.TIME (current tool age) > TIME2: Pocket or tool number (MP7480) of
the replacement tool and a T strobe M4073 are output and M4525 is set.
n
CUR.TIME (current tool age) > TIME2 > 0 and no replacement tool is
defined: After expiration of the time, the error message “max. tool age
expired” is displayed for this tool, and M4546 and M4525 are set.
n
CUR.TIME (current tool age) > TIME1: The NC sets M4543 and M4525.
You decide in the PLC what should happen when M4543 or M4546 is set (e.g.
display a PLC error message).
With M101, activate the automatic insertion of the replacement tool after
expiration of the tool age (TIME1 or TIME2). With M102, deactivate the
insertion. The tool is not changed immediately after expiration of the tool life,
but rather it varies by a few NC blocks depending on the microprocessor load.
In order to also be able to activate the automatic insertion of the replacement
tool with M128, you must program a retraction with M140 in the tool change
macro. After the tool change, the tool moves with an approach logic to the pre-
compensated position and then returns to the contour.
To synchronize the current machine status and the look-ahead calculation with
an NC macro call, (See “NCMACRO.SYS” on page 7 – 44).
No radius compensation is given in NC blocks with normal vectors. One delta
value for tool length and radius (DR, DL) can be entered for each tool in the
tool table. These delta values are taken into account by the TNC.
If the radius of the replacement tool differs from the radius of the original tool,
you must define this in the “DR” field. The delta value must always be
negative. If you enter a positive delta value, the error message “Tool radius
too large” appears.
You can suppress this error message with the M function M107, and
reactivate it with M108.
You can select whether the tool length is given with respect to the south pole
or the ball center of a spherical cutter:
7
7
7
7
With MP7680, select whether the tool radius (R2) should be taken into
account for the calculation of the tool length.
Note
In standard NC programs (NC block with RR, RL or R0), the same radius
must be defined for the replacement tool as for the original tool.
