Tool Control Functions
Chapter 20
20-25
This section assumes that tools have already been assigned to their specific
groups as discussed in section 20.5.1. This section discusses specific
information that is to be entered into the tool life management tables for
the individual tools. This information may also be entered into the tool
management tables using the programming method discussed in section
20.5.3. This information includes:
Tool length offset number
Tool diameter/radius offset number
Expected life of a tool
Renew a tool life
Tool length and diameter/radius offset number
This feature of tool life management is used so the programmer does not
need to know what tool has been called by tool life management and still
have the correct tool offsets and cutter compensation activated. Using this
method the programmer no longer needs to program an H or a D--word to
activate tool offsets or cutter compensation numbers, tool life management
will activate the offset numbers automatically.
Important: The control will only automatically enter the tool length and
cutter compensation offset numbers. This may or may not activate the tool
length offset (G43, G44) or cutter compensation features (G41, G42).
These features must still be activated as normal with the exception of the
fact that it is not necessary to program the H or D--word since it is
automatically entered by tool management.
Expected Tool Life
This feature of tool life management is used to set the expected life of a
tool. The type of tool measurement used is assigned to the tool group as
discussed in section 20.5.1. This tool measurement type determines the
units that are used for the expected tool life.
As a tool is used the amount of usage is recorded and displayed as the
accumulated tool life (the amount of the expected tool life that has been
used). This is displayed individually for each tool on the tool data display
screen. The accumulated tool life may be reset to zero by pressing the
{RENEW TOOL} softkey.
