Pressing ‘0’ and then the ‘
ORIGIN
’ button on the keypad at any time while on
the tool table screen will set all the tool pockets to ‘0’.
Tool Numbering System
Powering up the machine for the first time sets the default tool-pocket table.
The table is setup such that each pocket contains a tool with the same num
-
ber as the pocket number. The spindle is initialized to contain Tool 1 (T1). For
example, Pocket 1 is dedicated to contain Tool 1 (T1), Pocket 2 is dedicated to
Tool 2 (T2), etc. Therefore, the ATC 38 side-mount tool changer has a default
of 38 tools, T1 through T38 (T1 in the spindle).
The tool numbers in the tool table assigns a dedicated tool number to each
pocket of the tool changer. This number remains in the tool table regardless of
where the tool actually is. For example, if tool 5 (T5) is removed from the tool
pocket 5 and placed in the spindle, the tool table will indicate that T5 is in the
spindle and that pocket 5 is dedicated to tool T5.
A tool called for from the machine’s program commands the control to search
the tool table for the tool number and indexes the tool changer to the pocket
containing the tool number.
CAUTION! Damage to the machine and/or tooling can occur if the tool called for in
the program does not match the tool listed in the tool table and/or installed in the
corresponding pocket.
Acceptable Tool Numbers
In general the tool numbers are from T1 to the number of pockets in the tool
changer chain (T38 on a 30-pocket tool changer, however, it is possible to use
all the numbers in the tool table. This is done to allow for a situation where the
operator requires more than available tool pockets to complete the machining
job. An example is 55 different tools are required to perform a complete ma
-
chining job. The first 38 tools would be used and then the machine would be
paused while the operator removes 17 of the original tools and replaces them
with the 17 tools required to complete the job. After updating the tool table to
reflect the new tools in their respective pockets using tool numbers T39 through
T55 the machining job is ready to continue.
Using ‘0’ for a Tool Designation
A tool pocket can be labeled as an “always empty” pocket, by entering “0”
(zero) for the tool number in the tool table. If this is done the tool changer does
not “see” this pocket and will never try to install or retrieve a tool from pockets
with a ‘0’ designation.
A zero cannot be used to designate the tool inserted into the spindle. The
spindle must always have a tool number designation.
Use of “Large ” Tool Designations
The tool changer can accept oversized tools as long as the adjacent pockets
