Casting simulation is a computer technology that has matured over the past decade,
and is now available to any foundry with a PC. With simulation software the foundry
engineer can pour a "virtual casting" on the computer, designing the production
process before any tooling is built or sample castings are poured.
The next step in this technology is represented by a new product called
OPTICast, the result of a collaboration between Finite Solutions and Altair
Engineering. OPTICast uses mathematical optimization to guide the design process
automatically.
With most casting simulation software, the user creates a design, runs a simulation,
and then evaluates the results by plotting various output data to see if the results
are acceptable. If not, a change in the computer model is made by the user, and
another simulation is run. This is basically a "trial-and-error" approach. OPTICast,
on the other hand, takes an initial process design from the user and then allows
the user to specify which aspects of the design are allowed to vary and what the
desired outcome is to be. For example, the user could specify that riser sizes
are to be varied until yield is maximized while shrinkage porosity is held to
a specified level. OPTICast will then run a series of simulations using the SOLIDCast
package (from Finite Solutions), evaluate each simulation run, make a decision
on its own about what to change in the process design, and then run the next simulation.
This continues until the desired results are achieved. Thus, the foundry engineer
can start the process, walk away from the computer, and come back later to view
the optimum process design. This approach can maximize yield and minimize scrap
with very little effort, reducing energy and material costs as well as lead times.
Numerous in-foundry trials have resulted in up to 20% reduction in pour weight
with equal level of casting quality. For more information contact Larry Smiley
