Product Design Considerations

•
Net-shape manufacturing, if possible
Tolerances specified for functional needs
Surface finish specified for functional needs
Sharp corners should be avoided
Avoid undercuts
Deep holes should be avoided
Use standard stock sizes as far as possible
Use standard tooling as far as possible
Use materials with good machinability
Minimum machining set-up
Parts should be able to withstand cutting force
