OSHA inspections don’t just ‘happen.’ They are the result of some initiating circumstance that makes them a priority. OSHA inspection priorities  follow the hazards faced by the public that OSHA is charged to protect. While no lapse is desireable in one’s safety planning and execution, the highest priority items for OSHA should also be your highest priority to eliminate.

How many imminent dangers can you find?

Imminent danger situations. Hazards that could cause death or serious physical harm receive the top priority. As they should. Compliance officers (OSHA INSPECTORS) will ask employers to correct these hazards immediately. If the hazard cannot be removed, then the employees that are exposed should be.  Imminent danger and serious physical harm should not be part of working  in precision manufacturing.
Fatalities and catastrophes.  My take on this is that a catastrophe is an incident that requires the hospitalization of three or more employees. We all know what a fatality is. You must report these to OSHA within 8 hours. You can expect the OSHA follow up right away.
Complaints. If someone alleges that a hazardous situation exists, you can bet the agency will treat it seriously.  More seriously, in fact than referrals from other agencies.
Referrals from other agencies, organizations, or media. While these are not an assured way to initiate an investigation by OSHA,  they are considered.
Follow-ups (abatement). Checks to assure that violations cited from prior inspections are a lower priority, but remain a class of inspections that you can expect. Best prevention- Don’t have prior violations.
Planned or programmed investigations. The current National Emphasis Program  (NEP) on Recordkeeping is an example of this. These have been typically targeted at specific high hazard industries or workplaces that have high rates of injury and illness.
Whenever my team brought a problem in to me I asked them three questions.
 “Was there a procedure?”
“Was it followed? “
“Was it effective?”
 They always knew what the fourth question would be- Why not?
Do you have a procedure or system to assure that no imminent danger situations exist in your shop?
 Do you have a system to assure that your people are instructed, trained, and their knowledge reviewed to assure they follow safe and best practices?
Are you leading by example and setting the highest standards for safety, just as you do for quality and service, in your shop?
You know what the next question is.

 

High intention, sincere effort, intelligent direction, skillful execution.

Quality is never an accident; it is always the result of high intention, sincere effort, intelligent direction and skillful execution; it represents the wise choice of many alternatives.”
“Qualität ist niemals Zufall, sie ist immer das Ergebnis hoher Ziele, aufrichtiger Bemühung, intelligenter Vorgehensweise und geschickter Ausführung.”

ISM’s report of manufacturing’s expansion for the fourth , and economic expansion for seventh month in a row,  combined with PMPA’s  Business Trends Index improvement for 5 consecutive months,  confirm that we are in a recovery phase, rather than the free fall we just survived.
What should we be doing differently in the recovery phase, compared to what we  needed to do while we were free falling?

ISM values over 50 indicate expansion of manufacturing.

The latest Institute for Supply Management Manufacturing Report for November showed that Manufacturing expanded for the fourth month in a row. While the Purchasing Manager’s Index decreased from 55.7 in October to 53.6 in November, the fact that the November value is above 50 indicates that mnufacturing activity continues to expand.
The Precision Machined Products Association’s Business Trends Index of Sales  for October was up for the fifth month in a row, to 85, its highest value for the year.  Almost three quarters of PMPA Business Trends respondents expect industry sales to remain at current levels or increase.
This reinforces the signal from ISM’s New Orders measure, which climbed to 60.3 in November from October ‘s 58.5. (The tie-in for precision machined components and manufactured goods  should need little explanation- our products are the enablers of multiple technologies in automotive, appliances, aerospace, electrical/electronic, heavy truck, off road, and medical  products to name a few.
These are not the halcyon days of  “ship it, ship it, ship it.,” that seem like distant, almost forgotten memories. But ISM’s report of manufacturing’s expansion for the fourth , and economic expansion for seventh month in a row,  combined with PMPA’s  Business Trends Index improvement for 5 consecutive months,  confirm that we are in a recovery phase, rather than the free fall we just survived.
What are your doing differently now? What lessons have you learned? What is your new top priority every day?

Our industry works with some pretty amazing resolution and precision as our stock in trade. There are shops that look at tolerances in thousandths of an inch  (0.001″) . The thickness of a sheet of copy paper is around 0.003″,  and so a shop that can hold “half a thousandth,”  is saying essentially, that their total variation is on the order of one-sixth of the thickness of that sheet of copy paper. One-sixth of the thickness of a sheet of paper!
Some of our shops look at tolerances in terms of microns- that is millionths of a meter. A human hair can be anywhere within the range of 50- 120 microns, the average hair is probably  somewhere around 100 microns.
This means that the micron-calibrated  folks are measuring at precision levels that divide a human hair in about a hundred thicknesses, and a meter in millionths. That’s pretty impressive.
So I ran into this item  talking about about half a meter resolution, and I said, “Half meter resolution. Woo hoo- what’s the big deal? Thats no big deal.”
And then I saw what half a meter resolution looks like. From 684 kilometers (call it 425 miles ) up, taken while moving 7.5 km/second (thats 17,000 miles per hour, more or less.)

This is nothing compared to the photo on their site use the link below.

From Geoeye-1:  The Dubai Air Show. (Go to this site, and keep clicking on the picture until you see it in all its glory.) Want to see the Hoover Dam?
So while I continue to be impressed by the accomplishments of shops whose tolerances are anywhere from say a third of the thickness of a sheet of paper to one one-hundredth of the thickness of a human hair,  I have a new found respect for the resolution of, say, half a meter.  And I think we’ll all certainly be a bit more careful when we’re laying out by the pool…
So what is your best “resolution” or tolerance that you can hold, or held, under any circumstances? We’re looking for your stories, so drop us a line.

Thanks to you she can enjoy this moment.

All of us have many reasons to be grateful. To be thankful. To consider ourselves blessed.
Here is a link to an article that I wrote for the PMPA pages in  Production Machining Magazine. The article will give you a sense of how our industry contributes to the joy and quality of every day life. I hope that you enjoy it. The photo above is what inspired my column.
Thank you for doing your best at whatever it is that you do that makes our world a better place for someone, somewhere.

In this post we’ll take a look at the significance of the last 2 digits of the steel grade designation. We will be discussing carbon, not alloy grades.
The first 2 digits give us an idea about whether the grade is a plain carbon or alloy steel. See our post here. So 1018 is a plain carbon grade;  1137 is a resulfurized carbon steel; 4140 is an alloy steel.
So lets look at those last two digits in the 4 digit  AISI/ SAE grade designation, and what they mean in the carbon grades we see in our shops.
The secret to understanding real estate  is location, location, location.
In steel, the secret to understanding is carbon, carbon, carbon.

titanic hull trans21C
This is .21 Carbon steel from the hull of the Titanic.

Carbon is so important in understanding a steel’s characteristics, that in the North American nomenclature system, the last two digits of the grade are the average carbon content expressed as weight  %. Carbon is the most important indicator or predictor of a steel’s properties and response to processing.
So in that 1018 steel, 0.18 weight % carbon (on average) is implied; in 1137, 0.37 wt % carbon (on average) is implied; in 1144, the average carbon content we expect is, you guessed it, 0.44 wt.%.
So what does that mean to us as machinists?
Very low carbon. Grade 1008-1010. The low carbon content makes these steels low strength and very ductile. Typically used for cold heading. Cold forming. The machinist would characterize these as gummy. Chips are stringy, continuous, and soft.
Low carbon. Grade 1018; 1022. Low carbon means low strength. The non alloys in this range are weldable, and all of these grades are cold formable with out  the need for an anneal.  Grades in this carbon range are often carburized to achieve a high surface hardness. Not a good choice for machining, difficult to get chip to break.  Chips are somewhat continuous, and soft to semi-soft. Parts made from these grades tend to have low stock removal, and look like the bar that they were made from- bolts, light duty shafts, tie rods,  pins.
Medium carbon.  1045, 1137, 1144. Medium carbon means medium strength. Usually cold drawn. Can be heat  treated. Not recommended for cold heading. Welding requires special practices and residual control.  (Do not weld 11XX grades due to high sulfur content!)
Chips are continuous and semi hard (1030), continuous and tough (1035), and continuous and start to become springy or hard (1045-1050).  Small shafts, forgings, and kingpins are typical of these grades. Not usually annealed. Heavy draft (cold work) followed by a stress relief operation can get yield strengths into the 100,000 psi minimum. ASTM A 311 class B is one such designation, Stressproof (TM)  is Niagara LaSalle’s trademarked name for a similar product.
High carbon. Above 0.50 carbon, most of us start to describe steels as “high carbon.” Depending on the application, and carbon content, an anneal may be required for processing. My rule of thumb for carbon grades  is at 0.60 and above, an anneal is required prior to cold drawing. ( For alloys, generally annealing is required at 0.40% carbon.)   So a 1060 bar would be annealed prior to cold drawing.   The type of anneal for these steels would be called a lamellar pearlitic anneal. It would help to develop a  predominately coarse lamellar  pearlitic structure in the steel. Chips are continuous and range from hard (1060) to tough (1070) to springy (1080 and above).
Very high carbon. At 0.90  carbon and above, (drill rod and bearing steels) a different kind of anneal is called for. It is called spheroidize annealing, and results in a greater mean free path of ferrite between the hard carbide particles in these steels. Very high carbon steels are most machinable in the spheroidize annealed condition.
Adding sulfur to carbon steels is called resulfurizing. This addition provides a way to break up the chip, thus escaping the continuous chip that we get from 10XX steels. This is why 11XX and 12XX steels are so machinable.

The bill is H.R. 3548. 
The House passed the bill yesterday and the President is expected to sign it  today.

Call your tax advisor promptly!

You should consult your tax advisor immediately, as this bill provides for immediate tax refunds on taxes that your business has paid over the immediate 5 years, instead of the the usual 2 years for the tax period 2008 OR  2009  (not both!) There are other terms regarding the fifth year that we will not get into here.
The existing law per the stimulus bill only allowed for losses incurred in 2008, the language that PMPA worked to get passed added coverage for 2009.
Thanks to all  who responded to our Action Alert October 23. Your action and support of this important provision  has made a difference!

Put this subject on your watch list…
This act charges the EEOC with  issuing finalized regulations by November 21, 2009.

Bush signed it. Ted Kennedy acclaimed it.
Bush signed it. Ted Kennedy acclaimed it.

These regulations have not yet been finalized, despite the claims of purveyors of employment law posters who insist that you need  a new poster…
Title I of the Genetic Information Nondiscrimination Act of 2008 prohibits discrimination based on genetic information in health coverage and employment. Title II prohibits employment discrimination on the basis of genetic information. Title III  contains  numerous miscellaneous provisions including updates to child labor laws as well as establishing penalties.
The law requires full compliance by employers with 15 or more employees, employment agencies, labor unions, joint labor-management training programs, and all federal employers. GINA also updates language from ‘Handicap’ and ‘Handicaps’ to ‘Disability’ and ‘Disabilities’ in the existing EEOC code. This law extends HIPAA protections to genetic information.   Ted Kennedy called it “”the first civil rights bill of the new century of the life sciences.”
The implementing regulations from EEOC are not out yet, but here are some ‘tools you can use’ to prepare for the upcoming rules in November:
