Tooling and setup planner supports various decision making steps
related to bending tools and press-brake setups. Currently, it
supports the following tasks:
Tool Selection: For a given part it selects bending tools (i.e.,
punches, dies, punch holders, and die holders). Tool selection is done
by determining the most likely shape of workpiece for various bending
operations and selecting the minimal tool set (i.e., having the
minimum number of tool types) that works for these intermediate
Constraint Generation: For a given part and a set of bending tools,
it identifies the tooling-imposed ordering constraints on various
bending operations. These constraints are used for eliminating bend
sequences that will result in interference problems between the tools
and the workpiece. This step is performed by identifying various
features (i.e., collections of bends) in the part that impose ordering
constraints and generating constraints associated with these features.
Operation Sequence Feasibility: For a given operation sequence, it
identifies whether or not the operation sequence is feasible. This
step is performed by constructing intermediate part shapes and 3D tool
models and intersecting them to identify any interference problems.
Setup Planning: For a given operation sequence, it identifies the
best possible press-brake setup (i.e., which tool should be positioned
where on the press-brake). This step is performed by identifying setup
constraints for every bending operation and using a constraint
propagation technique to create press-brake setups which satisfy setup
constraints for every bending operation.
