Burrs and foreign object damage are consideration that are increasingly critical as precision machined parts are engineered from more challenging materials and to demanding geometries and applications.-  Guest Post by John Halladay of Vectron, Inc.
Burrs are unwanted raised material remaining on a machined part as a result of prior manufacturing operations. Link here

Looks like unwanted raised material  to me!

FOD can be either Foreign Object Debris or Foreign Object Damage  as defined by the
National Aerospace FOD Prevention, Inc. (NAFPI),
Foreign Object Debris (FOD): A substance, debris or article alien to a vehicle or system which would potentially cause damage.

Foreign Object Damage (FOD): Any damage attributed to a foreign object that can be expressed in physical or economic terms which may or may not degrade the product’s required safety and/or performance characteristics.

“Cause damage, degrade product’s safety or performance characteristics, and economic damage” – These are serious issues to manufacturers and their customers making critical human safety reliant systems- like automotive, aerospace, fluid power, or medical devices or systems.

So how do we deal with Burrs, and FOD? John Halladay of Vectron explains:

“Based on my experience (a few more years than I care to admit) there are some things to consider with difficult to see FOD and burrs.  Number one, hand deburring is typically out of the question—even with magnification.  If hand deburring does happen to remove the burr, the dislodged burr magically transforms itself into yet another source of FOD.  Mass finishing techniques (vibro, tumbling, Spinner, bead blast/water jet) will fall into the same trap.   They may be able to dislodge the burr or foreign object, but then that dis lodged item creates damage to the surface finish or features you fought hard to create in the part.”
“Thermal deburring is a batch process involving very intense heat in very short durations. It’s like being inside an explosion. Because it utilizes combustible gases under pressure, it has been proven to be extremely effective at removing the hard to see burrs we often encounter on the less machinable materials and alloys we see in our shops today. One advantage of  Thermal Deburring is that it does not create FOD, and the process will seek out other sources of FOD that may be lurking in some of the tightest geometries in the part.  There is nothing quite like an  explosive gaseous mixture to see and vaporize and remove all  unwanted debris on or in our parts!
Electro-Chemical Deburring, is usually referred to as  ECD.  It applies an electrical current to the areas where the burrs are located. The current carried by the electrolyte actually dissolves the burr material. This process can actually create a controlled radius on the workpiece by its action.”
Electro-Chemical  deburring is therefore quite useful for removing burrs at internal intersections, especially when a radius is either desired or required.  The downside of ECD is that it may not completely take care of other sources of FOD.  This is easily resolved with the addition of a special wash process in conjunction with ECD to get to “Yes” with your customer.
Due to the expense and engineering associated with these processes, and the intermittent need for them, these processes are seldom performed in house in contract manufacturer’s operations.  They are readily available from a number of job shops across the continent.  You will find that most shops will provide a no-charge feasibility analysis including sample processing, so there’s really no down side to investigating these options while you continue to search for possible in-house solutions.

This is what the customer wants. Thermal deburred and supercleaned.

"I have to get it right too?"

You wouldn’t use a gage that measures in 0.001″  increments for a requirement in 0.0001.” Why tolerate similar inaccuracies in your OSHA reporting work product?

Guest Post by James Pryor II, American Safety and Health Management Consultants, Inc.
Here are 5 tips to help keep your OSHA 300 up to requirements:

  1. Record ALL hours worked by ALL employees covered by the records – Hourly , Salary, Part Time, and Temporary
  2. If necessary, estimate  by multiplying the average number of workers by 2000 to obtain hours worked.
  3. Verify hours by  confirming against what amount was paid to unemployment insurance.
  4. If the hours  you report are too low (underestimated) the incidence rate will be too high.
  5. If the hours you report are too high (overestimated)  the incidence rate will be too low.

 Why is the incidence rate so important? It is the go / no go gage that will  determine whether or not your shop safety program gets a pass or a closer look. The DayAway and Restricted Time Report is a listing that is closely examined by OSHA. Too high an Incidence Rate will indicate a need for a review. Too low an incidence rate could give a false picture of your safety performance and lead to unintended consequences.
We don’t really have the technology to do a long form Gage R&R on your safety paperwork, but following these 5 tips will assure that your program “meets print.”
Use your passion for quality to assure high performance in all aspects of your shop’s safety program.The actionable information in your accurate OSHA 300 Log will help you continue to improve your shop’s safety performance.
