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
