NC FUNCTION 34. FUNCTIONS FOR PUNCH PRESS
323
Tool position compensation along the X– and Y–axes can be effected for
tools specified by a code consisting of character T and one to four digits
that follow it. The amount of compensation is specified in the least
command increment defined on the tool registration menu during
installation. (Up to 136 tools, values: Positive or negative number
consisting of eight digits)
CAUTION
If an inch/metric switch–over option is specified, and the
measurement unit used in the machine is different from that
used in the input system, a maximum possible error is the
sum of half the least input increment and half the least
command increment. This error will not be accumulated.
Set the maximum number of punches for each tool, on the tool registration
screen. When the number of executed punches for the selected tool
exceeds the maximum number of punches for that tool, the tool life
reached signal PTLCH is output. This signal is used to issue an alarm on
the PMC or request the operator to change the tool.
The number of executed punches and maximum number of punches can
be set and displayed by using the [TOOL] soft key on the
<OFFSET/SETTING> screen, and the [TOOL LIFE] screen.
