Here are some insights into the extra care and know-how needed to achieve success and build a successful reputation as a reliable supplier of micro machined parts.

The post What You Need to Know Right Now to Improve High-Volume Micro Manufacturing appeared first on Fabricating and Metalworking.

The growing need for production of miniature parts and features in medical and dental applications – as well as mold making, fiber optics, automotive, and other industries – has taken us beyond more sluggish EDM and laser processes. Such tiny tooling and part features are, by nature, challenging to manage. And at production-level volumes, achieving consistent quality is even more difficult. If you’re looking for ways to improve productivity with micro cutting tools, here’s what you need to know about . . .

We consider tools with diameters under 3 mm to be micro tools. It’s important to note that these tools aren’t simply smaller versions of their macro counterparts. They have geometric considerations all their own and you must understand them. For example, our Ø1mm Sphinx drill can run at 80xD. But this is only possible because, by design, the cylindrical shaping extends further down the tool, closer to the tip, to facilitate pecking and maintain strength.

Edges on micro cutters are not proportional to those of macro cutters – it’s just not possible. Because of the duller edge, the energy required for micro cutters relative to the MMR can be up to 10x higher than their larger version. Because of this, we recommend using the shortest micro tool possible to avoid deflection.

With such miniscule features, even a coating can negatively affect performance. This is because the coating fills in valuable flute space for proper chip evacuation, which is absolutely critical in these applications.

Use coolant only when absolutely needed and take special care when you do. These tiny tools are more sensitive than standard ones and even liquid flow can weaken their structure in the cut.

Often overlooked in micro milling, it’s critical that feed per tooth equals the cutting edge radius.

Chips and small tooling do not get along all that well. While trying to compensate for low spindle speeds with tools that have more flutes may help reach your ideal feed rate, chip evacuation will suffer. Determining the appropriate chip load – as close to the cutting edge as possible – allows you to operate at the highest possible spindle speed, speeding up the cycle improving surface finish and lessening the chances of built up edge.

Because such little stock is being removed, rubbing (instead of actual cutting) can occur which increases the chances of built up edge. This results in more required force and higher chances of deflection and/or early failure.

With requisite speeds for successful micro machining exceeding 60,000 rpm, quality micro cutting tools themselves are not enough to achieve success. You must also control important factors like dynamic runout and balance. You must have the appropriate holder, not only to ensure quality work, but also to preserve the life of your tools. When choosing a holder, for instance a micro collet chuck, keep in mind helpful attributes like a symmetrical design, a perfectly concentric collapse of the collet around the cutter, and a ball bearing raceway nut with precision-ground threads. Upfront costs may be higher, but preserving these specialized cutting tools will, without a doubt, save you money in the long run.

When runout occurs, the edge most affected takes over most of the cutting. The uneven wear leads the tool to failure much quicker than if the tool rotates about the centerline as intended. In one customer application, drilling into a steel workpiece 0.590 in deep with a 0.118 in diameter carbide drill in a holder with 0.00008 in runout accuracy produced 2,300 holes. A holder with 0.0006 in runout accuracy was only able to produce 800 holes. In this scenario, the shop could save hundreds of dollars a month in carbide costs – as well as labor costs due to less tool changing – by making one smart tool holder choice.

The balance itself does not change as speed increases, however, the forces it creates increase exponentially alongside speed. And at the high speeds required for micro machining, you’ll quickly see the impact.

Opportunities abound for shops to cash in on the seemingly ever-growing micro machining market. But it’s not as simple as increasing spindle speeds or using smaller tools. Miniature tooling is innately different than the more standard macro tools. The differences between the different types of micro tools vary from what you see in the standard tooling world. As such, the practice requires extra care and know-how in order to achieve success and build a reputation as a reliable supplier of micro machined parts. Whether you’re already a player in the micro game or are just starting to consider throwing your hat in the ring, hopefully these insights will help you grow and improve your work.

The Largest Qualified 3D Metal Part for European Aerospace is Here http://www.fabricatingandmetalworking.com/2016/08/largest-qualified-3d-metal-part-european-aerospace/ http://www.fabricatingandmetalworking.com/2016/08/largest-qualified-3d-metal-part-european-aerospace/#respond Wed, 24 Aug 2016 18:21:47 +0000 http://www.fabricatingandmetalworking.com/?p=98380 How do you economically produce huge parts with intricate geometry that has a tendency to warp but must withstand critical applications in a demanding environment? Here’s the answer.

The post The Largest Qualified 3D Metal Part for European Aerospace is Here appeared first on Fabricating and Metalworking.

Thales Alenia Space (Cannes, France), in collaboration with 3D printing service company Poly-Shape SAS (Salon de Provence, France), has additively manufactured parts for two new South Korean communications satellites, Koreasat-5A and Koreasat-7, that will launch into orbit in 2017 to provide coverage for South Korea, the Philippines, Indonesia, India, Japan, Indochina and the Middle East. The huge antenna supports on these two satellites each measure 447 x 204.5 x 391 cu mm and are the largest volume parts ever placed in orbit that were 3D printed by powder-bed-based laser melting of metals in Europe.

Aluminum is the most commonly used material for satellites due to its weight and thermal conductivity, high strength, rigidity and resistance to corrosion. Poly-Shape used an X line 1000R metal printing machine from Concept Laser (Lichtenfels, Germany) with a build envelope of 630 x 400 x 500 cu mm for 3D printing with aluminum and a closed system for reliable process and powder management in accordance with the ATEX directives. Its unique rotating mechanism allows two build modules to be used reciprocally to guarantee constant production with no downtime and simple and secure handling when arming and disarming the machine. The patented laser melting technology uses stochastic navigation to significantly reduce the stresses involved in processing the slice segments (or “islands”) of these very large parts and prevent warping to the maximum extent possible with balanced temperature regulation of the build envelope. Using this system, it took only a few days to print this large, bionic and intricate geometry.

In the following interview, Florence Montredon, the additive manufacturing technology development manager at Thales Alenia Space, and Stéphane Abed, the chief executive officer of Poly-Shape, discuss the manufacturing challenges associated with this project.

Which techniques and processes do you use to manufacture your products?
Montredon: Given the very low quantity of individual components for satellites and the small number of satellites in general, 3D printing is an ideal option for manufacturing. By comparison, cast parts (i.e. mold-based processes) tend to be more suitable for components that need to be manufactured in larger batches. By 3D printing the antenna supports of the Koreasat-5A and Koreasat-7 telecom satellites, we wanted to demonstrate how laser melting technology opens up numerous possibilities for our applications. The essential benefits are the short timeline from design and development through to the finished part, along with the high level of efficiency.

Abed: The X line 1000R machine is the only machine with a build envelope that is large enough for our 3D metal printing. There are currently no other alternatives, unless you use smaller build envelopes and then join the parts together – which carries the risk of weak points in the structure. One theoretical alternative would have been to print the parts in two halves and join them together, but we would have lost the benefit of reducing the amount of assembly work that is involved here. The joining process may also have revealed possible defects that can be ruled out with the one-shot option of laser melting. And by making only one part we can achieve our objective faster. Furthermore, on this machine we are also able to create not just aluminum parts that are customary in satellites, but also process reactive materials, such as titanium or titanium alloys, or also nickel-base alloys – all groups of materials that are vital in other areas of aircraft construction.

What were the particular challenges of building the biggest 3D metal part?
Montredon: The first challenge was that we needed two identical twin parts: one for Koreasat-5A and the other for Koreasat-7. But the principal challenge was the size. In comparison to our previous references and experiences, the dimensions of these parts were huge.

Abed: Examples of the issues involved were feasibility, the tendency to warp, geometry and the weight. Using CAE/CAD tools, the Thales Alenia Space designers managed to optimize the geometry to suit the process, save weight and meet the load requirements. They did a very good job. The final design was then further optimized and fine-tuned in numerous redesign stages, with close collaboration and interaction between Thales Alenia Space and Poly-Shape when it came to fabrication. What we have here is a bionically optimized design.

Montredon: Both antenna supports then underwent specific elementary ground tests. They will also be submitted to usual testing at satellite level, which includes a vibration test and high temperatures in a vacuum to simulate a required lifespan of 15 years in orbit.

What new experiences were you able to gain in this project?
Abed: Aerospace provides good training and practice to be at the forefront with additive strategies. 3D metal printing requires a design that suits the process so that the advantages of a digital approach can be fully exploited. The advantages in the freedom of geometry are huge and incomparable to anything offered by conventional manufacturing technologies: digital parts look different, do more, and tend to be lighter. Certain small and medium-sized batches are often the better alternative from an economic perspective, but the limits shift upward every year so this opens up more new horizons for AM.

Montredon: To deliver the high quality parts demanded by applications in space travel, there must be a strong partnership between the end user and the manufacturer – you must be able to rely on your partner. A close working relationship and mutual interaction, with teamwork and communication between our companies, was essential to meet the ambitious timetables.

How Clean is Clean Enough? Evaluating Air Quality http://www.fabricatingandmetalworking.com/2016/08/clean-clean-enough-evaluating-air-quality/ http://www.fabricatingandmetalworking.com/2016/08/clean-clean-enough-evaluating-air-quality/#respond Wed, 24 Aug 2016 17:52:00 +0000 http://www.fabricatingandmetalworking.com/?p=98363 Is your shop clean enough to fabricate components for medical devices? A proper diagnosis is necessary to solving an OSHA or FDA particulate problem. But before installing an air quality remedy, it helps to know your current particulate levels, exposure profile and airflow patterns. Let’s take a closer look at this evaluation process.

The post How Clean is Clean Enough? Evaluating Air Quality appeared first on Fabricating and Metalworking.

Is your air clean enough? Of course, the real question is: clean enough for what?

Meeting minimum OSHA regulations for indoor air quality (IAQ) is a must for every manufacturing facility. However, there are many reasons that companies may decide to go above and beyond these minimum standards. In addition to the obvious benefits for worker health, cleaner air pays dividends in worker productivity, morale, retention and recruiting. It also has another benefit: a clean facility that makes a great first impression. That can be especially important for companies fabricating components for the medical industry. If your facility isn’t making the right impression, it’s probably time to take a closer look at your air quality systems. The first step to solving a particulate problem is proper diagnosis. Before installing an air quality remedy, it helps to know your current particulate levels, exposure profile and airflow patterns. Here is a closer look at the evaluation process.

Visible dust on surfaces is a key indicator of air quality problems. However, to get a more accurate diagnosis of indoor air quality, you need to take some measurements. Measuring your current state will help you determine what kind of remediation is needed. Evaluation starts with measurement of dust concentrations at different points in your facility. Dust concentration meters will help to quantify your exposure risks by providing accurate measures of total particulate levels in their immediate vicinity.

If your processes generate a consistent amount of particulate at all times, it may be enough to take a few “snapshot” readings and average the result. However, if your processes are variable, you may want a unit that takes incremental measurements over a period of time to see how air quality changes over time as your industrial processes cycle. This type of analysis allows plant managers to see both “peak” measurements and total particulate exposure over the time period. Meters should be set up at breathing-zone height (roughly 5 ft off the ground) at key points around the facility, including next to the fume-generating processes and in other areas in the facility where people congregate such as workstations and aisleways. Taking measurements in a grid pattern throughout the building will help you see how fumes are propagating and where they tend to collect.

A clean, pleasant environment is a plus for any industry, but it is especially important when the FDA knocks on your door once or twice a year. Randy B., a facilities coordinator at a medical product manufacturing company, explains: “We give frequent tours to buyers coming from hospital systems and they appreciate a clean, orderly environment. It also matters for our annual FDA audits. Ultimately, they are looking at the quality of the finished product, but if the manufacturing side looks dirty, it sends a red flag.”

As weld fumes and particulates cool, they settle out of the air and onto horizontal surfaces, leaving a thin layer of visible grime throughout the facility. This is especially problematic when particulate impacts the finishing line for medical products. Before installing their current air quality system, Randy’s plant had a problem with particulate from the welding stations contaminating their powder coat line. The particulate ruined the finish, and affected components ultimately had to be scrapped. Cleaning up the facility air fixed the problem.

Understanding total particulate exposure is a good first step, but composition matters, too. Exposure risks depend on the size and chemical composition of the particles generated. For example, medical parts are often made of chrome alloys, titanium or stainless steel, each of which has their own exposure profile. To ensure that you are staying under safe exposure limits for dangerous contaminants such as hexavalent chromium, manganese or beryllium, you may want to conduct additional analysis.

Air quality engineers can approximate exposure levels for specific elements by analyzing the processes and materials being used and the total particulate levels. Total exposure levels to different elements can be extrapolated from the total particulate measurements if the composition of base metals, coatings and lubricants, and consumables is well understood. If these estimates show that you are close to exposure limits on one or more elements, you may want to consider further analysis to get precise measurements. Dust samples can be collected on special filters inside the dust concentration meter. Samples are sent away to a lab for chemical analysis, a process that generally takes about two to three weeks.

A third crucial component that air quality engineers will evaluate is how air moves through the building. Every facility has its own unique airflow patterns that influence how weld fumes propagate through the facility, where they end up, and where they linger. The dust concentration meter readings at different locations will provide important data. But designing an effective remedy also requires a more in-depth evaluation of the current airflow patterns. The type and location of existing ventilation and HVAC equipment, location of windows and doors, equipment position, temperature variations, and other factors influence airflow currents throughout the building. These currents can have a great deal of impact on the efficacy of dust capture and filtration equipment.

If you try to work against the currents, you will need a much higher capture velocity for your air filtration equipment, resulting in significantly higher energy use. Capture velocity needs are also impacted by the processes themselves. Processes that aggressively “push” particulates into the air will require much higher capture velocities than those that allow them to simply waft into the air, such as fumes rising from freshly welded parts in a cooling bin.

The evaluation process allows system engineers to take a more scientific approach to air quality system design. By understanding the volume, composition and movement of particulate throughout the facility, we can make better recommendations for mitigation and select the most cost effective solution to help you reach your goals. For example, we use a computer modeling program called Ventmapping™ to analyze data gathered during evaluation, model the facility layout and airflow patterns, and try out remedy options virtually.

So, is your facility clean enough? Sometimes you need more than your eyes to know for sure. Evaluation is the first step to creating a clean, healthy facility that will impress your employees, your customers and your OSHA or FDA inspectors.

The post Linear AMS Expands Tooling and Manufacturing Business appeared first on Fabricating and Metalworking.

With their acquisition by Moog Inc. (East Aurora, NY) only months ago, Linear AMS (Livonia, MI), formerly Linear Mold & Engineering, is announcing new investment in the molding and tooling side of its business with company veteran Lou Young heading the effort.

“We are a one-stop partner for everything from mold and part design through process qualification, and it remains critical that every employee knows that every task is about adding value to the customer,” Young stated. “With specialties including prototyping, mold building, and low-volume production for automotive and non-automotive companies, our 3D printing and metal AM capabilities are rewriting the manufacturing rules book. Tooling, however, remains the heart of production success. No one is bringing a stronger focus and solutions set, including 3D printing, than we are.”

The company is in the midst of adding two new account management experts for tooling and molding, in addition to new capital equipment at its Livonia, MI injection-molding facility. This is all aimed at supporting an already strong, customer-centric culture, according to Young. “We’re at our most effective establishing collaborative problem-solving and custom solutions with our customers centered on design, engineering, prototyping, and low-volume production,” he states.

“General interest in 3D printing and additive manufacturing is white-hot right now,” Young adds. “The ability to incorporate 3D printing with traditional tooling allows us to offer established companies innovative solutions for their existing manufacturing processes (e.g. molds and castings) together with new 3D metal-printed components that can make those existing tools much better. For companies making millions of parts, a cycle time reduction of 25 to 30 percent can be pretty disruptive, both from the part design side and from the production side.”

What do such companies want to know about? “Mainly design techniques for cooling channels, water lines, and how we could optimize inserts for particular parts,” Young answers. “With our knowledge and experience both on the 3D side printing metal inserts and our mold manufacturing expertise, we can go further and simulate how those optimized designs not only work better, but maybe in 30 percent less time. We can’t mention names, but we are able to present testimonials from customers who not only used the concepts, but showed we were able to hit the improvement marks we predicted. We consider large companies that mold millions of plastic parts annually leaders because they have their molding systems down to a science. Being a part of introducing them to a disruptive technology that can drastically change their core business, is profound to see and something we intend to continue.”

Production molds with 3D printed conformal cooling lines are a company specialty. “As opposed to drilled holes, 3D printed heating or cooling lines are designed to follow the contours of the part,” Young stated. “Placing them an optimal distance from the part surface means the mold can maintain a constant temperature and avoid warps and sinks. Testing these cooling lines with finite element analysis means we can fine-tune conformal cooling lines to accurately predict optimum mold performance and improved cycle times.”

Linear AMS has qualified cycle-time reductions from 15 percent up to as much as 45 percent. This not only means reduced energy output, but also extra capacity for a customer. Other tangible benefits include less scrap, improved final part quality, and much more flexibility when it comes to part features and the mold components necessary to make them.
