Anna The Manufacturing Maven: Blog #2
This week, I had the opportunity to work in the labs with our Director of Operations, Mike Davis. He explained and demonstrated the complete process of production for a customer’s part.
The Process
Mike Davis working with Engineers in the lab.
In the words of Sun Tzu, author of The Art of War, “Every battle is won before it is fought.” This is true because of planning. At Potomac, we follow well-thought procedures, carefully designed for the jobs we execute. These various procedures, like coding, testing and preparing, occur even before the parts begin to run.
Step 1: Proposal
A job starts when a customer reaches out with a problem. The team meets to discuss a plan of action on how to best approach the project. Once a consensus is drawn, the sales department sends out a quote.
Step 2: Creating a Prototype

After finalizing everything with the customer, it’s time to begin production. (For the job I observed, the customer requested holes drilled into a delicate glass, and therefore, Davis opted for a UV Laser due to the absorption spectra of the glass).
With a rough drawing of the proposed part, Davis renders adjustments to the customer’s blueprint to fit the scale of the device. He then implements these measurements into a code that supports our lasers.
After developing the program, Davis moves to the lab to begin testing the part. Before running the laser, he adjusts the beam, using a system of lenses and mirrors. The laser runs one sample before Mike sends the prototype for the first article inspection. Quality Control ensures the piece matches the proposal and then full-scale production may begin.
Step 3: Production
When the model finally meets his expectations, Davis grants the next task to a technician, who monitors the laser and troubleshoots, should any unforeseen problems occur.
Step 4: Quality Control and Distribution
Following the manufacturing aspect of the job, Quality Control inspects the parts before distributing them to the customer.
Winning the Battle
The projects completed at Potomac range from medical tools involving cell research, to advanced leak detection devices. With a broad set of capabilities, many jobs may run at once. To successfully manage multiple assignments simultaneously, organization and standard processes must be in practice. Like Sun Tzu said, you must try to win the battle first.
While the customer only sees the final result, the process of manufacturing these devices can be fascinating. Thanks to Mike for allowing us a closer insight of the work done at Potomac Photonics!
Animal testing has long been an established protocol in drug discovery programs. But there are systemic issues with the far from reliable methodology. In fact, only 10% of the drugs that move from animal testing to human clinical trials succeeds. Such low yields increase the time and expense required to get pharmaceuticals to market, fueling…
In the field of microfluidics, where precision is key to innovation and application success, our expertise at Potomac Photonics sets a standard. We specialize in the art of laser drilling precise small holes in glass slides and coverslips, a critical capability for the fabrication of microfluidic devices. These devices play a pivotal role in various…
The world today seems consumed with fears about Artificial Intelligence, otherwise known as AI. Writers, journalists, ad copywriters, teachers, and artists are fearful their jobs will be lost to computers but in manufacturing we have been applying a subset of AI to manufacturing for decades with positive results. Like other forms of AI, Machine Learning…
