Abstract
The ability to quickly introduce new quality products is a
decisive factor in capturing market share. Because of pressing demands to
reduce lead time, analyzing the manufacturability of the proposed design
has become an important step in the design stage. This paper presents an
approach for analyzing the manufacturability of machined parts.
Evaluating the manufacturability of a proposed design involves
determining whether. or not it is manufacturable with a given set of
manufacturing operationsand if so, then finding the associated
manufacturing efficiency. Since there can be several different ways to
manufacture a proposed design, this requires us to consider different
ways to manufacture it, in order to determine which one best meets the
design and manufacturing objectives.
The first step in our approach is to identify all machining
operations which can potentially be used to create the given design.
Using these operations, we generate different operation plans for
machining the part. Each time we generate a new operation plan, we
examine whether it can produce the desired shape and tolerances, and
calculate its manufacturability rating. If no operation plan can be found
that is capable of producing the design, then the given design is
considered unmachinable; otherwise, the manufacturability rating for the
design is the rating of the best operation plan.
We anticipate that by providing feedback about possible problems
with the design, this work will help in speeding up the evaluation of new
product designs in order to decide how or whether to manufacture them.
Such a capability will be useful in responding quickly to changing
demands and opportunities in the marketplace.
