How More Part Information Can Lead to Better Pricing
When engineers send a print to us, the drawing usually communicates important requirements through details like tolerances and finishes. Those are essential, but they do not always tell the full story of how the part will actually function in the real world.
At Focused on Machining, we often ask customers for additional information about their parts and projects because what we learn can change how we approach the work. With greater context, we can align our machining strategy with your project’s priorities.
Learn why we can deliver a better quote when we know more about how a part will be used.
The Application Can Clarify Tolerances
We can machine parts with very tight tolerances, and we know that some applications make tight tolerances absolutely necessary. As an AS9100 Rev. D machine shop, for instance, many of our components will face punishing conditions in space that require expert tight tolerance machining.
But sometimes, a tolerance may be tighter than the application truly requires, and that may drive costs higher than necessary. When we understand the function of the part, we can ask better questions. If a tolerance can be relaxed without affecting the final assembly, that may create an opportunity to reduce machining time and cost.
Structural Parts Require a Different Approach
Another helpful piece of context is understanding whether a part is structural or non-structural.
If a component is part of the solid structure of an aircraft or rocket, we need to be especially careful about how we machine it. We do not want to put unnecessary heat or stress into the material or weaken the part through our machining.
Mounting Details Can Change the Fixturing
A standard machining setup might involve holding material in a vise. But if the part will not experience that kind of force when it’s being used, squeezing it in a vise could create stress that causes movement once the part is released.
In those situations, we may choose a different workholding strategy. We might make a custom fixture, for example, or use another method that better mirrors the way the part will be used. We aim to machine and inspect the part in a way that is as close to the real assembly as possible.
A Case Study in the Importance of Context
One of our recent projects involved a waveguide, which helps guide radio signals through an antenna system and into a computer for processing. These parts can be extremely precise because the internal geometry affects how signals move and how certain frequencies are filtered.
In this case, the part had an internal channel that turned 90 degrees, with tight tolerances on the width, height, and end-to-end dimensions of the channel. Because so much material had to be removed internally, the part began to twist slightly during machining.
After talking with the customer, we learned how the waveguide would be bolted into the final assembly and how other waveguide sections would attach to it. With this information, we made our own fixture to simulate that mounting condition, using the same hardware the customer specified. Once the part was mounted that way, the twisting was controlled, and we were able to machine and inspect it more efficiently.
Better Information Leads to Better Pricing
Sharing more application details can create a more reliable process for both engineers and buyers. If we know important details about your part upfront, we can help you meet your most important priorities, whether that’s tight tolerances or improved pricing.
Precision Machining for Aerospace Engine and Motor Parts
Many aerospace, defense, space, and drone propulsion applications depend on hard, exotic metals that can handle extreme environments. Those materials can be challenging for many suppliers, but at Focused on Machining, our experience gives us the confidence to machine complex, tight-tolerance components from them.
Why Propulsion Components Require the Right Partner
When the application is an engine, a rocket motor, a thruster, or another propulsion component, the requirements are rarely simple. These parts need to withstand very demanding environments and operating conditions, including significant temperature swings and intense forces. In many cases, they’re also tied to programs that have little room for delays.
That combination makes experience extremely important. A shop that has little experience with these materials may underestimate the lead times or machining challenges involved. In this type of work, a missed estimate can create delays of weeks or months as problems build on each other.
Our Experience With Difficult Metals
Many engine and rocket motor components are made from materials such as:
These materials are often selected because they can perform in difficult environments. But those qualities can also make them significantly more challenging in aerospace machining than aluminum or standard stainless steel.
While many machine shops avoid them for that reason, at our AS9100 Rev. D machine shop, we have spent years learning how to manufacture precision components from them consistently. That experience changes the way we approach an RFQ. An Inconel quote does not create uncertainty for us. We understand the tooling, coatings, feeds, speeds, and process planning needed to produce the part while protecting the customer’s schedule.
Accurate Planning for Tooling, Cost, and Lead Time
One of the biggest challenges with exotic materials is that the true cost of the job is not limited to the raw material. Tooling can become a major factor. A tool that lasts for thousands of parts in a more forgiving material may have a much shorter life in Inconel or A286.
Because we understand that up front, we can build realistic tooling expectations into the quote instead of discovering the issue during production. That creates more accurate pricing for the customer and helps prevent surprises after the job begins.
The same experience helps improve lead-time accuracy. For these projects, it is important to have the right tools and equipment ready before production starts. We routinely machine tight tolerances in these materials and can create complex components with 5-axis machining, but the success of the job depends on planning the full process correctly from the beginning.
The Supplier Network for Better Results
Customers also benefit from our extensive and trusted supplier network.
For instance, exotic materials can be harder to source than common metals, and availability can vary significantly from vendor to vendor. But for our projects, we reach out to multiple trusted suppliers to compare pricing and lead times. In some cases, the first vendor may need to source it from a mill, but we’ll be able to find another supplier that has the material on the shelf because of our connections.
That visibility helps us make the right decisions for customers when we’re managing their material sourcing or post-processing. If speed matters, we can identify the path that supports the schedule. If cost is the priority, we can help evaluate the best available option.
Choosing the Right Machine Shop for Engine Parts
The truth is that, for OEMs and defense suppliers, the most important factor in choosing a supplier should be experience. A shop with real experience in exotic metals will quote more accurately and deliver more reliably.
3 Recommendations for Revision Control Best Practice
In manufacturing, revision control is a topic that rarely creates issues because both manufacturers and engineers take it so seriously. But when best practices break down even in small ways, they can create risk for everyone involved.
At Focused on Machining, we have strong systems in place to catch revision issues before they reach the shop floor. Even so, we have a few recommendations for revision control best practices to keep the manufacturing process clear from the beginning.
1. Don’t Restart at Rev A for an Existing Part Number
This is a rare issue, but it’s one we’ve seen happen after acquisitions or rebrands. A new team may inherit an existing part number and want to treat the current design as its new baseline. To them, restarting at Rev A is logical.
We understand the idea, but from a manufacturer’s point of view, that creates serious risk. If we have already made that same part number through Rev A, Rev B, Rev C, and beyond, our ERP system already has those revisions in its history. The current revision may be Rev J or Rev N, while the previous versions are archived. If a customer sends the same part number back to Rev A, there are now two different Rev A versions connected to the same part number.
We have extensive safeguards in place to prevent rev control issues, but this still creates an avoidable risk of confusion. If an order is entered against the incorrect Rev A, the incorrect part could be manufactured and delivered before anyone realizes the issue. At that point, both sides have lost time and money.
2. Be Clear With Your Manufacturing Partner About What Changed in a New Revision
When you send us a new revision, it’s helpful to identify specifically what has changed from the previous version. We are able to compare prints and work through the differences, but that process takes time. We may have to review the print callout by callout to be sure we didn’t miss anything.
A simple summary can make a major difference. When you give us context, we can quote the revision faster and plan the work more efficiently. Without it, we may need to treat the job almost like a brand-new part because we can’t afford to assume anything remains unchanged.
3. Treat Every Change as a New Revision
Even small changes should be controlled through a new revision. Customers may inform us that they slightly altered the hole size but didn’t change the rev. That change may seem minor, but it can affect tooling, setup, inspection, and the way the job is processed. If the print still says Rev A, but the part is no longer the same Rev A we made before, the risk of a mix-up increases.
This most commonly occurs with notes on the print. Even when the geometry does not change, updates to the notes should still be handled as a new revision. A different finish, material requirement, inspection requirement, or outside process can affect what needs to happen after precision machining. The part will not be the same from a manufacturing standpoint.
If anything at all changes on the print, the safest thing to do is issue a new revision.
Good Revision Control Protects Your Timeline
Strong revision control allows us to quote faster and deliver the correct parts on schedule. Our ERP system and review processes help us catch many potential issues, but following best practices can also help prevent any confusion.

Why Defense Primes Should Still Look For CMMC Level 2 Suppliers
By Justin Quinn, President and Owner of Focused on Machining
A buyer from a large defense prime recently reached out to us at Focused on Machining. He was looking for a new defense supplier that could take on programs that require CMMC Level 2 compliance.
We were happy to talk to him about his program and provide a quote. We are currently 95% complete with our CMMC Level 2 preparation, with a clear Plan of Action and Milestones (POA&M) in place.
But that conversation made us realize something: a major challenge is on the way across the defense manufacturing supply chain. The defense industrial base is under pressure to move faster than ever; at the same time, CMMC requirements may soon be phased into DoD contracts, even as the next phase of implementation is under review.
This combination could create real timeline issues for primes and suppliers that wait too long to act.
The Potential CMMC Supply Chain Crunch
The buyer told us that much of his recent time has been spent searching for CMMC Level 2 suppliers. Historically, his company had a large supplier base and could choose from a wide range of capable shops.
But with CMMC requirements continuing to evolve, that flexibility is beginning to shrink. And this change is happening against a broader push across the defense industrial base to strengthen supply chains and deliver critical capabilities at greater speed and scale.
Many of the suppliers this buyer currently works with are talented small shops that have supported defense work for years. But some haven’t looked deeply into CMMC, while many others intend to be compliant eventually but have not taken meaningful steps yet.
At this point, the next phase in implementation could bring CMMC Level 2 third-party assessment requirements into the award process. Even with the timeline paused, it’s risky to wait; suppliers that have not started may still be looking at a year or more of work before they are truly ready.
The buyer told us he was reaching out now to get ahead of this potential issue. He saw that we had experience with primes along with our CMMC Level 2 self-assessment, and wanted to add us as a partner before he lost other suppliers and programs experienced disruptions.
What Defense Suppliers and Machine Shops Should Do Now
At this point, even after the recent pause, I do think it’s incumbent upon suppliers to start taking concrete steps. CMMC is a serious commitment, and I understand why many small shops have been cautious. It requires time, planning, outside support, new processes, and ongoing expenses.
I also understand the financial concern. CMMC is not inexpensive, and the recurring costs are real. But in our experience, the investment did not happen all at once. The process unfolded over time, with expenses spread across multiple phases. That made it possible to manage the work piece by piece instead of treating it as one massive project.
There are also resources available from the government and from people in the industry who have already gone through the process. I have shared some of what I learned along the way in my previous articles, and I’m always happy to talk with other shops trying to understand what comes next.
What Defense Primes Should Do Now
Primes, above all, should not wait until requirements are clarified again to evaluate their supplier base.
Many suppliers may not fully understand how much work is involved in becoming CMMC Level 2 ready. If a shop isn’t already well down the road, they may not be ready in time.
The best step is to begin adding new suppliers now. Some of your existing suppliers may eventually complete the process, and primes may be able to move work back to them later. But to avoid disruption, it is better to identify CMMC-ready manufacturing partners before a program is at risk.
Where Focused on Machining Stands Today
As of July 2026, we are:
95% complete with our CMMC Level 2 preparation.
Working toward full CMMC Level 2 certification this year.
Following a clear Plan of Action and Milestones (POA&M), with remaining items scheduled for completion within the next 30 days.
Scheduled for our audit in early fall 2026.
Let’s Talk About Your CMMC Project
When I served in the Air Force as an aircraft mechanic, I would sometimes look at the parts I was installing and think about the path they took to get to me. I wondered what the markings and numbers meant and where the parts came from. Eventually, that curiosity helped lead me into manufacturing.
Because of that history, defense work is personal to me. As a defense supplier and service-disabled veteran-owned small business, I feel a patriotic obligation to take the responsibilities of CMMC seriously. I’m proud of the work we have done to prepare.
And I also want to do my part to make sure the broader defense supply base stays strong. If you are a shop trying to navigate CMMC, please reach out, because I’m happy to talk. And if you are a prime looking for manufacturing partners who can meet CMMC Level 2 requirements, let’s discuss your program.
Understanding Lead Times: The Factors Customers Can Help Control
At Focused on Machining, customers sometimes approach us with tight timelines, and they’re looking to find out how quickly a project can move forward. We do everything we can to support aggressive schedules, but between our own capacity and outside processes, lead times can depend on a variety of changing factors.
That’s why reducing lead times starts with understanding what the machine shop can directly control, what depends on outside factors, and what customers can do to help prevent delays. When all sides understand these factors, projects can move faster.
What the Manufacturer Directly Controls
The steps we control most directly are the ones that happen under our own roof. These include precision machining, inspection, hardware installation, and other in-house operations required to complete the part.
Because these processes are part of our daily workflow, we can plan for them carefully and adjust schedules when needed. Our ERP system plays an important role in that process by tracking jobs in detail and planning capacity. We can make the best use of the time and resources available to us.
Material acquisition is another area where we usually have a strong degree of control. In many cases, standard materials are readily available, and proper planning on our end allows us to source them quickly. There are exceptions, of course. Specialty materials or short supply conditions can affect timing. But under normal conditions, material procurement is typically a manageable part of the schedule.
Where Customer Requirements Can Slow Down Projects
From a customer perspective, it can be most helpful to focus on factors you control that can influence lead time. Two factors we’ve recently seen have been approved supplier lists and source inspections.
Approved Supplier Lists
Approved supplier lists can be a major factor because they limit the options available for materials, inspection, and outside processing. For example, one customer recently needed a material that was ultrasonically inspected. The material we procured had already been ultrasonically inspected from a mill, but that mill was not on the customer’s approved supplier list, so it had to be reinspected before production began.
Approved suppliers can also delay finishing or post-processing. If a project requires a specific approved supplier rather than any qualified supplier that meets the right standard, that vendor’s capacity and location can add to lead time.
When possible, we try to help primes expand their approved supplier lists to prevent issues like these from affecting their schedules.
Source Inspections
Source inspection can also add time at the end of a project. Even after parts are machined and inspected, some customers require us to submit a data package and wait for their source inspector to review or release the shipment. If the inspector has several days to respond, that step can add nearly a week once paperwork, review, packaging, and shipment are all considered.
The Best Way to Save Time: “Overprovide” Details at the Start
The fastest way to save time on a project is to provide as many details as possible about your project when you’re first submitting your quote. Print, model, and quantity are an essential start, but more information can help us quote more quickly and plan accurately from the start.
For example, even if you tell us you need 200 parts, we need to know what that will entail. Is that an urgent one-time delivery, or a three-year quantity that might be better suited to contract manufacturing services? A production schedule allows us to understand whether the project fits our capacity, and it also helps us determine if we can find creative ways to support your requirements.
Other factors that can provide helpful context:
Are these parts currently being made by an existing supplier?
Is there a first article inspection requirement before production can begin?
Is the part coming to us after another process, such as 3D printing, casting, or outside fabrication?
Have you already learned something from previous production runs that we should know?
These allow us to understand your priorities. But without you offering them upfront, a project that could move quickly may require several follow-up conversations before we know how to proceed.
Where Outside Processes Affect Your Timeline
Some project steps fall somewhere in the middle. Outside processes such as plating, coating, heat treating, passivation, painting, or other finishing services, for instance, do not fall directly under our control.
Many projects are sent to outside vendors we choose from our trusted network, and we understand that their performance reflects on us. Even so, we cannot fully control another company’s internal schedule. If a finishing vendor is already at capacity, that can extend the overall lead time, even if the machining itself is completed quickly.
In some cases, expediting an outside process may help. However, we are cautious about recommending expedites for certain operations, especially complex plating or finishing work that requires masking. Rushing those steps can increase the risk of errors. If a part has to be reworked, the project may lose more time than the expedite would have saved.

Lights-Out 5-Axis Machining for Complex Defense Parts
At Focused on Machining, we speak extensively with defense primes through project collaborations, as well as at trade shows and other industry events. In those conversations and in our discussions with other defense manufacturers, we hear a common theme: the defense industrial base is under pressure to move faster.
No single company can solve that challenge alone, but we take our role seriously. That’s one reason we’ve invested in advanced equipment and automation to help increase our lights-out capacity for complex defense parts.
5-Axis Machining to Reduce Timelines
We have long embraced automation, but we never stop improving to turn your parts around faster. One clear illustration is a complex antenna component we make for a defense customer. The part has positional tolerances of less than a thousandth of an inch, with certain feature locations held to within seven ten-thousandths of an inch. Precision is central to the part’s performance.
When we first began manufacturing this part, we ran it on one of our horizontal mills. We met required specifications, but the process was slower than we wanted it to be. It required careful fixturing, and because tolerances were so tight, we had to manually indicate certain features to confirm accuracy. These manual steps added to timelines.
Today, we manufacture the same part on our 5-axis mill, improving cycle times. Even more significantly, the 5-axis machine is reliable enough to run this complex part lights out, reducing production timelines.
Repeatability Is Critical for Speed in Defense Machining
Our 5-axis equipment is highly accurate and robust, and its palletized setup allows the machine to be fed continuously, even for tight tolerance machining. When we first transitioned the antenna component to the 5-axis mill, we checked parts frequently to make sure the machine was holding tolerance throughout the run. After the first batch, our quality team found that the final part we produced was just as good as the first.
That kind of repeatability is essential to defense machining. It’s what allows us to run lights-out at night with total confidence in the results. We can take advantage of more hours of production, while maintaining fewer setups and better access to complex part features.
And now, we are ramping into even more complex 5-axis work. One part currently in production has a cycle time of nearly 22 hours, and we plan to run it unattended around the clock.
Building Reliable Processes for Lights-Out Production
Lights-out precision machining requires confidence in both your equipment and your processes. Our most senior programmer handles our 5-axis projects, and he brings years of programming and machining knowledge.
There is one central principle in our lights-out programming: the goal is stable, reliable processes instead of pure speed. We need quality parts without intervention, and in many cases that requires a more conservative approach rather than aiming for aggressive cycle times. Our programmer pays close attention to tool life, workholding, chip evacuation, and controlled cuts.
We’ll Help Defense Customers Move Faster
Primes need a manufacturing partner that can produce complex parts while still moving quickly. Focused on Machining offers lights-out machining to help increase throughput and reduce timelines for your defense parts.
