Optimize mechanical part design before manufacturing
Joly Concept can optimize your parts before manufacturing to reduce cost and part
fabrication turnaround. Tweak your part geometries to make them easier to manufacture.
Review your part tolerances to define precision only where it is needed. Apply geometrical
tolerances to prevent or allow deviation that might occur while the part is being
manufactured. This will also ensure that you get a part that is within the specification
required by your project, nothing more or less than what is needed.
Geometry optimization is making small changes to a part so that lower cost, more
easily available, common tooling can be used in the manufacturing process. Having
custom tooling made can greatly affect the target date deadline if a supplier has
to acquire special tools to make complex geometries. It is favorable to avoid features
that require special tooling for manufacturing.
Tolerance optimization is changing the allowable deviation in size, shape and position
to the features of a part. Using different tolerances to features depending on its
importance to the overall functionality of the final component. This can ensure
faster manufacturing time of the part or the assembly.
Surface finish optimization is allowing for different finishes to features of a
part. Allowing for rougher finishes in some areas while producing smoother higher
grade finishes on other more functional or esthetic areas. This is to reduce manufacturing
time without changing the mechanical functionality of the part.
Forecasting internal stress that can cause part deformation and its impact on the
main functionality of your part and overall interaction with other components of
an assembly. Material removal to manufacture a finished part from solid blocks
of material tend to change the stresses within the initial material. These changes
to the initial stock material tend to warp the finished product.
Usually, the initial stock material is clamped in some fashion while material is
being removed to create the finished product. This process changes the internal
stresses while the part is in a constrained condition. After the machining operations
are completed, unclamping the part puts it in an unconstrained condition. The changed
stresses in the part can make it bend and warp to some degree. This can be anticipated
and planned for. Part warping does not always have consequence on its functionality.
If it does, stress relieving methods must be used before or during the manufacturing
Part esthetics is a major factor in the design process. A slight modification in
part geometry can completely change the look of a component. Adding a turning operation
will definitely change the manufacturing process in the example presented to the
right. It will probably not have a dramatic impact on the overall manufacturing
time. It does, however, have a major effect on the look of the part without changing
