OPERATION
These tool changers allow the control to rotate the carousel to the next tool needed while the previous tool is
still in the spindle. When a tool change is commanded, the two tools are swapped by the tool arm. Thus, a tool
will be taken from one pocket and returned to another. This means that carousel pockets are not dedicated to
any particular tool.
Tool Pocket Set-up
To initialize a pocket to a particular tool, scroll to that pocket, enter the tool number and press ENTER. To
initialize the pocket as empty, press 0, ENTER.
Pressing ORIGIN at any time while on this screen will set the tool pockets to default values. For example, tool
1 in the spindle, tool 2 in pocket 1, tool 3 in pocket 2, and so on. Thus, a machine with a 24 pocket carousel
can handle 25 tools.
Pressing 0, ORIGIN at any time while on this screen will set the tool pockets to all zeros.
To designate a pocket as "large" (meaning that the pockets on either side will remain empty,) scroll
the highlight to that pocket on the screen and press "L", WRITE. An "L" will appear on the screen next
to this pocket, and the tool numbers on either side will be changed to "-". To remove the "L" and change
the pockets on either side to zeros, press SPACE, WRITE.
If the carousel contains a mixture of large and normal size tools, tool changes will often result in normal
size tools being placed in pockets designated as large. When this happens, the control will automati-
cally change the upper case "L" to a lower case "l". When another tool change results in a large tool
being placed in that pocket, the control will automatically change the "l" back to "L".
If the operator loads all the large pockets with large tools and loads another large tool in the spindle, it will not
be possible for the control to change to a normal size tool unless one pocket is designated as "1", meaning a
large pocket containing a normal size tool. To designate such a pocket, scroll to that pocket and enter "l",
WRITE. A lower case "l" will appear beside this pocket. To clear it, enter SPACE, WRITE. Note that only one
pocket can be designated by the operator with "l". If a second pocket is set to "1", the previous one will be
automatically changed to "L".
If the spindle currently contains a large tool and a normal size tool is needed next, the control will have to swap
the large tool with a normal size tool that is in a large pocket, and then (assuming it is not the right tool) swap
that tool for the one that is needed. Thus, in such a case, two tool changes will be performed.
The areas most affected by this feature are the tool change and tool changer restore functions. There are a
number of parameters and alarms that support these tool changers.
Note: If alarms occur while using a Vertical Mill side-mount tool changer, the
associated parameters should first be verified (and corrected if necessary)
then the tool change recovery procedure should be performed
