Seven Steps To Increase Productivity in Your Precision Machining Shop

Posted December 10, 2010 8:30 AM by Milo

Productivity - What Can I Do Today To Make My Shop The Most Money?

In the current economy, many machines are down for lack of work. This makes it essential to assure that the ones with work are up and running every minute that they should.

Can you meet this simple challenge in your shop? For every production machine that you have scheduled for operations, does it have actual production uptime of greater than 50%? Actually measured in minutes of tools in the cut. Reported. Documented. Reviewed.

Any item that steals machine uptime is stealing money from your business.

Here are 7 steps you can take today to increase machine productivity in your shop:

  1. Record and investigate the causes of machine downtime in your shop.
  2. Record frequency – how many.
  3. Record severity- how long.
  4. Record by machine.
  5. Prepare a Pareto Analysis.
  6. Assign a cross functional team to investigate root causes.
  7. Implement corrective actions and review their effectiveness.

Solutions to system problems nearly always require a team approach. Have the team study the issues identified in the Pareto Analysis not just as specific delays, but as classes of delays. Then they can work on uncovering, and eliminating the organizational root cause of that class delay.

In my experience, root causes are often institutional failings - inadequate training, inadequate maintenance, false economy on tooling, all of which are systemic problems requiring management attention.

"Quality is everybody's responsibility," I often heard when I was on a crew.

"The authority to permanently eliminate the root cause rests with management," is what I muttered under my breath.

You are the Champion. The final arbiter.

Your team will identify the problems, find the root causes, and identify possible permanent solutions.

As champion your job is to help them "Make it so."

"Make it so"

Pareto Analysis , authored by Duncan Haugey, was found on the Project Smart website. http://www.projectsmart.co.uk/. Project Smart was launched in 2000 as a way to provide easy access to information about the project management profession.

We once had a life-threatening safety issue. I identified the problem I identified the solution. I brought the problem and solution (turning the key) to the proper authority. They agreed that there was a problem and came up with an easier solution. They fired me.

Hi Gazu,

Sorry for the firing!

This indicate the most important fact: Be safe yourself first, and safe others after. That way you will be a hero.

Never forget the order it must happen, Gil.

Machine downtime is bad. Human downtime is a real killer financially.

Companies have to keep enough people on the payroll to run the machines, whether orders are coming in or not.

Hi Marat,

You put the finger on the real problem! "Human" downtime or other concerns to the operator are more important than any machine problem. Machine doesn't work without human contribution.

First, process capability depands of MAN, METHOD, MACHINE, and MATERIAL as mentioned in a "cause-and-effect diagram". See wastes or difficulties in that order.

Also, eliminate wastes to the operator as motion and waiting or change methodology.

Finally, eliminate wastes for the machine, waiting time for transfer of pieces, changing bits, disks, or other working objects, motion of the pieces, and most importantly defects due to processing. Material could be imposed!

After all these, you have to take care about the machine itself, and do what it took to the operator. Use the "cause-and-effect diagram" to pinpoint what need to be corrected or changed.

"K. SUZAKI: The new manufacturing challenge" will help everyone, Gil.

I used to do many bids and budgets and always added 20 percent.

This worked in isolation from the government, though I was not isolated really.

In this era I do feel that paradigms for all businesses have shifted to be similar to some of the most uncertain businesses, like publishing, or the arts, out of which I come.

Criminal and underground operational procedures and financial arrangements are all now pretty much the same, as detailed in Eric Schlossers Reefer Madness.

I am aware I am not being particularly comprehensive and just took a quick read again of the Pareto PDF coming to the mind that it was valid when there was some security of regulation and law that seems missing, and pushes all to more of the 50 50 sort of thing where you expect to lose 50 percent of all you do to changes and theft.

P.S. I was impressed that the Governor of NC put out an edict that Bureaucrats were not to be allowed to just change rules and fees whenever they felt like it independent of oversight by elected officials.
