GibbsCAM Tombstone Management System
Tombstones are a very productive means for machining multiple parts, greatly extending
the time a machining center can run without operator intervention. GibbsCAM TMS
(Tombstone Management System) streamlines multi-part setups to move more material through a machine tool while dramatically reducing the overall time required to create
error-free machining processes.
The TMS dialog provides all the options
needed to machine a tombstone full of parts—
whether it's the same part duplicated in a
number of locations, different faces of the
same part, or different parts altogether
Flexible Part Layout
Define the tombstone, the multiple parts on it
and how tools should move from part to part.
- Set up a standard configuration of parts
where the same configuration is used on all
sides of the tombstone.
- Set up a custom configuration to support
multiple types of parts or part conditions
that can vary from one side to the next.
Optimize Tool Changes
Group similar operations to control which
operations should be performed together to
minimize tool changes and rotations of the
- Group operations by tool to machine all
features—in order and across all parts,
including those accessible on adjacent sides
of the tombstone—with the same tool
before the next tool change.
- Group operations by tool and coordinate
system to complete all operations on a
workpiece with the same tool before
moving to the next.
- Because some tools may be used for several
operations, the user has the option to have
one tool perform only one operation in one
group at a time.
Avoid collisions by defining the safe distance
when moving from part to part on each face
of the tombstone and when indexing from face
to face of the tombstone.
The Machine Simulation module provides
visual verification of the complete setup—the
tombstone, fixtures, and workpieces as well as
critical components of the machine tool such
as the rotary table, base plates, machine
columns and so on. Apparent problems can be
corrected easily by simply returning to the
TMS dialog and modifying the input.
Simulation also keeps track of X, Y, Z positions
relative to the machine's travel limits to
prevent the tool from exceeding the machine's
Output a program for the entire tombstone of
parts, including all index moves and tool
retracts. Support is provided for how the
posted output subroutines, canned cycles, and
B rotation positions will be handled.
