Exact Metrology Scans Celebrity Soaps

Exact Metrology: A Division of In-Place Machining Company and a comprehensive 3D metrology service provider and hardware sales company, recently used Blue Light Scanning technology to mass produce celebrity-themed soaps. These soaps will be sold by a non-profit for charity.

Blue Light Scanning, a form of structured light scanning technology, operates by using a combination of projector, camera and a lens system. By using a projector, a pattern of light is created and the shadowed, dark areas on the object get measured for data collection. The scanner utilizes optical non-contact technology to capture millions of accurate points in a single fast scan.

Noah Branscum, Exact Metrology Application Engineer for Short Range Scanning, working at the company’s Cincinnati office, completed the soap scan. Steps involved using reference points to help the scanner understand where the carved head is in space. Then, he took a “scan” using the scanner to display the lines of blue light onto the part and had two cameras reading how the lines refracted off the part, producing multiple lines of 3D points in space.”  After going around the part to take several scans, Branscum proceeded to use reference points to stitch each scan together. He then created a .stl file of the 3D scan data by way of a “mesh”, using ATOS Professional software. This software is used to operate the sensor head, process the 3D point cloud data and to edit and post-process the data. Besides polygon mesh generation and editing, additional features include sensor control, sectioning and primitive generation.

Discussing the challenges of scanning these famous faces, Branscum commented the scanner was limited in its “line of sight.” “Things like between the eyes and eyelids can be a bit though, or where there’s very sharp valleys like the lips.” Thankfully, ATOS Professional also helps fill in the holes with feature and character line detection.

Asked about future projects like this, Branscum concluded, “We love challenges and this was a fun experience for us. We look forward to working on equally challenging projects in the future.”

Exact Metrology Employee Discusses Additive Manufacturing

Greg Groth, the Brookfield, Wisconsin Division Manager, was part of a panel discussing additive manufacturing, its challenges and opportunities

Greg Groth
Greg Groth

Exact Metrology: A Division of In-Place Machining Company and a comprehensive 3D metrology service provider and hardware sales company, had one of their employees give a presentation on 3D scanning and how to use it. Greg Groth, the Division Manager at the company’s Brookfield, Wisconsin location, presented at Rapid+TCT, North America’s largest additive event. Held recently at McCormick Place in Chicago, Illinois, Groth was part of a panel discussion entitled “3D Scanning: Why do it and how.”

He discussed Exact Metrology’s capabilities, with an emphasis on CT technology. Groth also cited how CT fits into the company’s business model and how it supplements additive technology. In addition, the discussion covered the challenges that arise with complex additive parts and the need to incorporate 3D scanning into the quality process that validates parts.  He also shared several examples of complex projects Exact has performed over the years.

When talking about additive manufacturing today, Groth said that there is a growing need for evaluation of additive parts once they are made. “We are naïve to the thought that even though additive circumvents the traditional manufacturing restrictions (draft/shrink) when making parts, the end result part is not perfect.”  He added that these parts need to be validated. Due to the fact that additive parts are so complex, inspecting them is a challenge. Thanks to CT scanning, this has become easier.

Even though CT technology has helped capture internal geometry for additive manufacturing better than other methods, there are still limitations of material penetration. Part design should think about the way the part will be inspected, whether using contact or non-contact measurement techniques.

Depending on the complexity of the part, most additive substrates can be scanned using structured light or laser scanning. However, complex powered metal substrates are feasible for CT scanning if their material properties and scale don’t impede the penetration of the X-rays on the CT scanner. The denser the material, the more power is required.

In conclusion, Greg Groth said, “I think all additive markets can find value in the scanning and validation process. With the wide variety of scanning technology available, I don’t think any market is untouchable.”

Exact Metrology Reverse Engineers an Impact Driver Body

Exact Metrology: A Division of In-Place Machining Company and a comprehensive 3D metrology service provider and hardware sales company, recently reverse engineered an impact driver body.  

Impact Driver Body

Reverse engineering involves digitally deconstructing products to extract design information from them. Thus, users can determine how a part was designed so that it can be recreated. Although the process tends to imply that 3D scanning will be used solely for product design, it can be used to address many other engineering functions. These include product design and manufacturing, facilities maintenance and plant engineering, architectural and civil engineering and custom manufacturing.

While there are many ways to reverse engineer, CT scanning was used due to plastic nature of the impact driver body. CT excels in digitalizing small plastic parts. This impact driver body was scanned using the ZEISS METROTOM 6 scout. This CT scanner digitizes complex parts including the internal geometries at the finest level of detail. Users obtain a complete 3D image for GD&T analysis or nominal-actual comparisons.  The combination of a 3k detector and 225 kV X-ray enables ZEISS METROTOM 6 scout to provide high contrast, high-resolution measurement results and exceptional sharpness of detail. As a result, even the smallest defects in the part become visible and can be analyzed to the last detail. Furthermore, CT scanning quickly captures data and one scan can be used for void analysis, inspection, volume porosity, etc.  A 5-axis kinematics with integrated centering table helps clients optimally position the part in the measuring volume and the control of the device and the metrological evaluation of the data are combined in a single software package, making additional software or intermediate steps redundant.

Reverse engineering process

Greg Groth, the Division Manager at the company’s Brookfield, Wisconsin office explained that the impact driver body although relatively ubiquitous, presents many challenges in the digital modeling process. One of these challenges includes the complex geometry. The smooth outside ergonomics can be difficult to duplicate and interpret with traditional CAD functionality. According to Groth, “We used a combination of hybrid NURBS (Non-Uniform Rational B-Splines) modeling to duplicate the smooth, sculpted surfaces and combined them with traditional mechanical CAD features to create the part shape.”  Another challenge with plastics components is replicating complete parting lines from the original tooling to make the part. These can zig-zag around the part depending on the geometry and are sometimes omitted or cleaned up at the factory. The final challenge involves compensating for warp and shrink during manufacturing, as injection molding is used. Once the formed part starts to cool, it may change its shape. Predicting the movement and compensating it back to the intended design was time consuming.

Exact Metrology Scans Sculpture by Tennessee Artist

Exact Metrology: A Division of In-Place Machining Company, a comprehensive 3D metrology service provider and hardware sales company, recently scanned a sculpture by a Memphis, Tennessee artist, Sarah Elizabeth Cornejo, a resident at Crosstown Arts in Memphis.

The sculpture is based on a growing sinkhole that has not been fixed and is getting worse. Cornejo was looking for a metrology company that could capture all the details. An artist friend, who had worked with Exact Metrology in the past, recommended the company to her. After contacting Exact Metrology, Sarah Elizabeth sent her sculpture to the company’s Cincinnati, Ohio location for CT scanning. The sculpture was made so that it could be held.

CT scanning is an x-ray methodology yielding 3D results by placing an object on a rotational stage between an x-ray tube and an x-ray detector, rotating the object 360 degrees and capturing images at specific intervals. In order to render the 3D x-ray model of the part or object, the images are then reconstructed. CT visualization software allows users to slice through in any direction to produce optimal views and images required for the analysis of the internal configuration.  CT scanning is the only way to get 3D views inside a part and also the only way to get true dimensional data without cutting up or destroying the object. In addition, very little time is required to capture data and troubleshoot parts. Lastly, a single scan can be used for void analysis, inspection, volume, porosity, reverse engineering, etc.

Powered by CT scanning, company personnel were able to send Cornejo the data she needs to scale it to the purposes of a 10 foot sculpture. The sculpture will be installed on the campus of the University of Memphis. The sculpture is immersive, so visitors will be able to walk into it. It is made of hardware cloth, aluminum fencing, epoxy clay, asphalt from Memphis and acrylic paint. The interior has reflective beads.

Sarah Elizabeth Cornejo is an interdisciplinary artist. Her work proposes a futuristic mythology for humanity where humans have evolved into hybrid beings with animals and insects. She is the co-founder and co-curator of BASEMENT, a provisional artist-run space in Chapel Hill, North Carolina. She is also a 2021 New Public Sculpture Fellow with the Urban Arts Commission in Memphis.

Talking about her collaboration with Exact Metrology, Cornejo said, “I came into this project not having much of an idea of what was possible from a 3-D scan but having a sense of what I was hoping to do with it in order to scale up my sculpture from ten inches to ten feet. Exact Metrology was incredibly patient in taking time to learn about the project, asking what I needed out of the final scan, and then talking to me about their recommendations for how to get the information I was looking for out of my maquette. They took time to trouble shoot the different possibilities, communicated with me along the way with some progress scans, and ultimately got me the result I needed to move forward with the piece.

Exact Metrology Scans Vertebrae Plate

Exact Metrology: A Division of In-Place Machining Company and a comprehensive 3D metrology service provider and hardware sales company, scanned a titanium cervical spine locking plate. The scan was completed by Brendon Belongia, an Applications Engineer at the Brookfield, Wisconsin office using the ZEISS METROTOM 6 scout.

The METROTOM 6 scout digitizes complex parts including the internal geometries at the finest level of detail. Users obtain a complete 3D image for GD&T analysis or nominal-actual comparisons. High- resolution images can be captured for precise measuring tasks or detailed inspections of internal structures. Be it shrinkage holes, pores, cracks, sink marks or warpage, all defects or deviations can be detected nondestructively.  Furthermore, the combination of a 3k detector and 225 kV X-ray enables ZEISS METROTOM 6 scout to provide high contrast, high-resolution measurement results and exceptional sharpness of detail. As a result, even the smallest defects in the part become visible and can be analyzed to the last detail. A 5-axis kinematics with integrated centering table helps clients optimally position the part in the measuring volume and the control of the device and the metrological evaluation of the data are combined in a single software package, making additional software or intermediate steps redundant.

With this CT scan, the company demonstrates its ability to scan even the smallest part, such as 4 mm. This vertebrae plate was measured within a 5-micron resolution and used a deviation color map with the GOM Volume Inspect software. The color representation of a point cloud or mesh data set is compared to its intended, nominal CAD model.  This spectrum of colors can tell users how far a value deviates compared to the CAD surfaces. Thus, a weak spot can be detected and can be fixed before a part is used.

The ability of the ZEISS METROTOM 6 scout to see the tinniest defect or detail is especially crucial for medical devices, especially those that go into the human body.

Exact Metrology’s new CMM

Exact Metrology Now Offers Large Scale CMM at Moline Facility

Exact Metrology, a comprehensive 3D metrology service provider and hardware sales company, is excited to announce that a large scale Coordinate Measuring Machine (CMM) has been installed at their office location in Moline, Illinois.

Installing the CMM

This machine is a high-accuracy CNC coordinate measuring machine that guarantees a maximum permissible error of E0, MPE = (2.5+3L/1000)μm. With this machine, measurement uncertainty remains within one-fifth of the dimension tolerance up to 30.2” (766mm). The higher accuracy specification therefore gives it more than double the effective measuring range in terms of accuracy-guarantee capability.

In addition, the room the machine sits in is temperature controlled.  From sensors installed on each axis scale and working in conjunction with sensors placed on the workpiece, temperatures are obtained before outputting the measurement result to the controller. The combined axis scale/workpiece temperature compensation design used gives superior results compared to systems with sensors only on the axis scales.

This CMM offers a maximum drive speed of 693 mm/s and a maximum drive acceleration of 1,732 mm/s2 resulting in an increase of drive distance in one second. Combining high speed and high acceleration, this machine reduces measuring time. As the number of measuring points increases, measuring costs per point are reduced.

It will be used by Exact Metrology for precision machined parts and has a measuring volume of 47 inches by 78 inches.  Components, parts and finished durable products that are designed to maintain extreme tight tolerance margins, as well as a high degree of durability are essential and common drivers for the use of precision machining. Precision machined parts typically have intricate features and need precise specifications and measurements. Additionally, many of these parts have holes, grooves, tapers, and/or textures that require an exact fit into other components. Precision machining is used in numerous applications such as: aerospace, medical device components, electronics, oil and gas, etc. CMMs don’t need the “old school” method of calipers, measuring tapes, and/or rulers.

Commenting on this new arrival, Exact Metrology co-President, Dean Solberg, said, “We’re very happy to install this machine and we’ve even heightened our ceilings and reinforced our floors to make sure it fits inside our facility.  We look forward to using this CMM to further our customer service reach.”

Scanning with the Leica RTC360

Exact Metrology Showcases Its Long Range Scanning Capabilities

Company highlights equipment and tools used, applications and the Leica RTC360

Exact Metrology, a comprehensive 3D metrology service provider and hardware sales company, offers a variety of long range (20 feet to entire facilities) high-definition technologies.  The company uses high quality equipment from Leica, a Hexagon Metrology company, and Surphaser®.

The tool of choice for long range scanning is LIDAR (Light Detection and Ranging) scanners. It’s a remote sensing method used to detect objects in 3D space similar to the technology used in autonomous self-driving vehicles. A highly accurate and effective surveying method, it uses light in the form of a pulsated laser to measure variable distances.

Leica RTC360

Long range scanners are typically set up in multiple locations to collect very large data sets. The data set from each location generates a point cloud and each of the point clouds are stitched together to create a 3D space. The stitched point cloud data is then sent directly to the customer or 3D models of the areas are generated to work in any CAD environment. The ability to implement CAD modeling allows tasks to be completed in a fraction of the time as opposed to manual drafting. It also eliminates the need to revisit the area to get that dreaded forgotten measurement or extra detail.

Generally, the CAD models are used for factory/shop floor layout plans, power plant equipment change outs, proof dimensioning and much more. The same data set can also be reused for multiple purposes.  It is ideal for large scale interior or exterior buildings, statues and historic architecture preservation.

In addition to the 3D model, full spherical HDR imagining is attached directly to the point cloud giving a photo realistic effect of the data and allowing for virtual walkthroughs of the areas, shareable markups, geo-referencing and meta-tagging. This data can be shared with an unlimited user base via a freeware software.

The Leica RTC360 3D reality capture solution can be controlled through the Leica Cyclone FIELD 360, app, allowing a real time visual of all the customer’s setups and the ability to optimize links of each  individual scan to all the setups.

Known for its unsurpassed accuracy and scan quality, long range scanning is ideal for use in reverse engineering, dimensional control, historical preservation, architecture and forensics.


Exact Metrology is ISO, AS9100 Certified as well as FFL and ITAR Registered.

Exact Metrology, with facilities in Cincinnati, Ohio, Moline, Illinois and Milwaukee, Wisconsin, plus affiliated offices throughout the country, is a comprehensive metrology services provider, offering customers 3D and CT scanning, reverse engineering, quality inspection, product development and 2D drawings.

Large machining parts (inside Strohwig)

Exact Metrology Provides Scanning and Training to a Forging Company and a Machine Shop

Strohwig Industries is a large, family-owned tool and die, injection mold and custom machining shop that helps turn the ideas of engineers into reality.   The company was founded in 1978 by Mr. Wolfgang Strohwig and his brother-in-law Larry Glass in Polk, Wisconsin. The initial location had only 600 square feet of space and a single Lucas Boring Bar. Located today in Richfield, Wisconsin, Strohwig Industries has 180 employees with a 225,000 square foot facility. With 56 horizontal and vertical CNC machines and the ability to handle over 100 tons, Strohwig is well equipped to handle large machining.

Brad Bucholtz, the company Quality Technician, explained Strohwig’s mission as, “The design, manufacture and repair of medium to large forging dies, plastic injection molds and metal die casts, as well as the manufacture of custom contract parts and/or components.” They machine a variety of steel (H-13, stainless steel, castings, forgings) and aluminum components. The company serves various markets including aerospace, automotive, mining, defense, building assembly, oil and gas, energy, marine, etc. This is why they decided to use Exact Metrology equipment for their inspection needs.

Brad said they’ve worked with Exact Metrology for over ten years. Initially, the company provided metrology services. He added that before 2010, there was no need for metrology as company employees manually inspected jobs that needed it. Working with Exact Metrology, Strohwig bought a Hexagon Romer Arm in 2016 and Leica Tracker in 2019. When the Romer RS6 scanner was released Exact Metrology offered a trade in on the older Romer arm. The productivity increase was so great it was easy to justify the investment of the new arm/scanner. This equipment came in handy when Strohwig received a request from a major Midwestern forge that has a long-standing relationship with them.  

This metal forging company in Illinois has a 126-year history and specializes in open die forging and rolled ring forging. The company was using Coordinate Measuring Machines (CMM) but needed to upgrade their equipment. A new job required precise measurability of a large forged part with complex geometry. Dean Solberg, Exact Metrology co-president suggested that they invest in scanning technology. Thus, the company purchased a Leica tracker, as well as PolyWorks software. Leica Absolute Tracker AT960 features an all-in-one integrated design, single-box probing system and smart connectivity. Additional features include continuous measurement, entry-level probing with T-probe and 2 Handheld laser scanners. One is an 8” line scan and another is a 24” line scan to capture huge amounts of data quickly.   The System is IP54 Certified for protection against dust and other contaminants.  PolyWorks|Inspectorwas used to verify the quality of the part through the use of high-density point clouds and contact-probe datasets. The scan was performed in a working environment, not a traditional lab, which meant that personnel were doing this while forging occurred. In the past, Strohwig machined various parts for them.  Now, this forge had Strohwig test for compliance vs. non-compliance in one of their forged parts.  

To do this, Strohwig used the Hexagon Romer Arm and the Leica Absolute Tracker. The portable measuring arms allowed company personnel the flexibility to measure on the machine shop or the floor. It featured no honing procedures, simplicity of operation and reliable 3D measurements. The Absolute Arm 7-axis delivers tactile probing and laser scanning in a uniquely ergonomic package. Once this was completed, they used PolyWorks|Inspectorto verify the quality of the part by using a color map. In the future, the company is looking to purchase additional Exact Metrology products.

Strohwig was able to coordinate with the company as they use common platforms to communicate and shared daily emails and PowerPoint presentations with their results. Brad Bucholtz used data mergers to combine the Romer and Leica data sets into one report.

Since using Exact Metrology, Brad said, “We are able to provide detailed reports to our customers. Also, we’re able to perform in-process inspections to validate specific processes.”  He further commented that Exact Metrology allowed them to supply a superior product and their deliverable to the customer has greatly improved.

When referring to the benefits of working with Exact Metrology, Brad noted, “Training only goes so far. After initial training, there are many stumbles and Exact is always there to make sure we get the knowledge we need. Onsite or offsite, they go above and beyond the call to make sure we can provide our customers with the data they need.”

SIDEBAR:  In a short video, Brad Bucholoz, Strohwig Quality Technician, describes Strohwig as company in business for 43 years that specializes in plastics and die cast molds and large contract machining parts. Tasked to test for compliance vs. non-compliance of a forged part by a Midwestern metal forging customer, Bucholoz highlighted that Strohwig uses the same hardware and software as their customer to communicate more accurately with them.  This included the use of  PolyWorks|Inspector™  Leica Absolute Tracker AT960MR and the Hexagon Romer Arm. The Absolute Tracker was used in conjunction with the Leica Absolute Scanner LAS-XL and T-probe.  Bucholoz mentioned that Exact President, Dean Solberg and the Exact team have always been to help and that he sees this relationship continuing into the foreseeable future.
