Johnson Thesis Idea

1. What causes them?

   • Operator awareness
   • Operator Skill
     • Should a study be done to monitor the amount of tools an operator uses to monitor their skill level?
       • Would paying for more training of an operator be a good investment?
   • Material
     • Can changing a material to a more expensive alternative, actually be cheaper than going through excessive deburring procedures?
     • What materials result in the most burrs?
     • What materials result in the least burrs?
   • Part Handling
   • Tool Quality/Condition
     • Can increasing the frequency of tool changes, result in a cheaper maching process overall?

2. What prevents them?

   • Chemicals like Rustlick
     • Time?

3. Why are they a problem?

   • They can interfere with moving parts
   • Danger to assembly operators.
   • Increases potential for leaks in certain applicaitons.

4. How common are they?

   • Burrs are almost always a product of machining sheet metal, but it becomes a problem when the burr is in certain locations and of a certain size.

5. What is a burr?

   • a rough edge or ridge left on an object (especially of metal) by the action of a tool or machine.

6. What gets rid of them?

   • Thermal deburring
   • Manual deburring
     • Time?
       • Cost?
