Optimize mechanical part design before manufacturing


Objective:

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.

Description:
Sharp corners removed

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.

Part tolerance modification

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.

Possible part deformation

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 process.

Part with slight change in geometry

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 its functionality.
