Scanning vs. CMM…a Short Comparison of Technologies

Long-established technology of Coordinate Measuring Machines (CMM) is today being challenged in myriad markets by fast-emerging, highly advanced science of blue light scanning

For over 50 years, the benchmark for accuracy in measuring solid objects, whether machined, molded, die cast, welded or forged, was the coordinate measuring machine.  Using a solid granite base table typically, along with a vertical, horizontal, gantry or bridge-mounted arm and touch probe, measurements would be taken and compared in blocks to an engineering file, first as 2D drawings and today as CAD files hosted in the cloud.

CMM

Typical CMM probes a part’s external dimensions at a limited number of touch points

During the last two decades, however, a “new kid in town” has arrived on the scene, with power, size, point capability and price value that are rapidly leaving the CMM technology in the dust.

3D laser scanning, plus the latest trend of industrial CT scanning, which is based on the same technology used for medical MRI, permit an array of points to be read, both external and now internal, on a wide variety of substrates and manufacturing techniques.  3D scans are made on many types of metals, composite, thermoplastic, elastomeric, wood, fiber and fabric materials, while CT scanning permits internal exploration of a thick aluminum casting, injection molded plastic or rubber part, even prepared foods, packaging, archaeological finds and fine art. The old joke is, with CT scanning, we would have known about Venus de Milo’s arm problems, long before they occurred. CT scanning can produce results for porosity, dimensional, failure analysis, volume and fiber orientation, all while leaving the part undamaged.

3D laser scan can capture millions of points, instantly comparing them to a CAD file or cloud-resident data

In contrast to conventional tactile CMM techniques, laser and especially CT scanning captures all surface points simultaneously, on even the most complex, convoluted surface areas.  As an example, where a typical touch probe might capture 300 points of reference for comparison to a CAD overlay, the laser or CT will capture millions of points.  Typical systems today can offer measurement accuracies to 4+L/100µm referring to the VDI 2630 metrology guideline.

A customer recently came to us with the following scenario.  An engineer at his company was boasting of having produced the “perfect part,” based on CMM deviation points.  Our contact had used our scanning services in the past.  We performed a quick blue light 3D scan on the object and quickly determined the part was out of spec on several faces, as certain critical points had been missed in the CMM protocol.  Our millions of scan data points were fit to the deviation map and the problem was tracked backed to the production source and rectified.  Today, this company is a regular customer.

CT scan enables the internal examination of a die cast, molded or other solid part, even food and packaging, to detect issues of porosity or void analysis without destruction of the object, as well as seal integrity

The above example does not indicate CMM technology has outlived its usefulness, by any means.  We continue to use it in our operations for certain measurements in many applications.

One important point to note is that the same software that manipulates the data from the CMM can be used with 3D scanners and CT equipment alike.  As there are substantial cost savings to be realized in the purchase of a 3D scanning device or the new generation of table top CT scanners, depending on the parts being examined, the transition from CMM to 3D or CT is more feasible today, economically.  The driving factors for a company, when evaluating the service vs. purchase issue are two.

The easier factor is raw cost, where a 3D scanner is typically half the cost of a CMM for measuring comparable part sizes. The other is more complex, namely the talent of the personnel doing the work. Experienced technicians have the ability to scan and process large data sets on a wide variety of substrates, geometries and part sizes effectively.  Coupled with the part volumes being processed and other factors, it is often more practical and profitable for a company to use a scanning service on an as-needed basis.

3D printing allows quick sampling of modified designs, as well as finished prototypes, producing parts directly from the scanned data

An additional point to note in evaluating CMM vs. scanning is the time involved. To derive those 300 touch points referenced above might take four hours, while the 2.5 million points derived from a 3D scan would take 30 minutes. Since Polyworks software can be used on a CMM or 3D laser scanner, the time and money savings quickly accumulate. Plus, in this manner, companies can develop something of a “universal metrology” scenario at their companies by augmenting the existing CMM technologies with 3D and even CT scanning capabilities, making their QC department more powerful from the outset. One practical note: We can train QC, R&D and production department personnel usually in three days or less to expand their capability from CMM to include 3D and CT scanning.

In terms of the data created, the 3D scanning produces color maps, inspections, first article inspections or other outputs. What you do with the data after completing the scanning is endless.

On the topic of substrates, it should be noted that CT scanning today offers the ability to evaluate a wide variety of dual thickness and dual density materials, with disparate examples ranging from an automotive firewall that might have differing thermoplastics or rubber and TPE materials co-molded to a candy bar with chocolate and nuts.

Exact Metrology Offers Tips on Airfoil Scanning Procedures

 Market Leader in 3D and CT Scanning Details a Typical Airfoil Procedure

Exact Metrology, a leading supplier of 3D laser and CT scanning equipment and services details the steps to a successful airfoil evaluation.  

Exact Metrology AirfoilSCAN PROCESS:

The scan can occur at the customer’s facility or at Exact Metrology’s. In many cases, it is most cost effective for the digitizing or scanning to take place at the Exact facility. However, in certain instances, when turnaround time is of great importance or downtime of the scanned component is critical, the scanner is mobile and available for onsite operation.

The airfoils that are typically provided by customers will be received by Exact Metrology for full documentation with photos, measurements and any surface markings or serial numbers recorded prior to any high definition scanning.

Setup

The mobility of the Exact scanner allows a high degree of flexibility in performing onsite scans (Option A) at a customer facility or the more cost efficient in-house scan at the Exact facility (Option B).

Due to the reflective nature of the blades, a thin coating of Magnaflux spray is applied. The SKD-S2 spray is a second phase of the crack checking processes. Phase 1 is a die penetrant that will not be used typically. The spray meets the requirements for AMS 2664, ASTM E165 and is ASME approved. (Health – 1, Flammability – 4, Reactivity -0, No Specific Hazard). See MSDS 0166 for more information on the SKD-S2 product.

When scanning the blade, Exact uses a fixture device. Targets will also be used to constrain data during the alignment phase. Targets will be placed using magnets on either side of the air foil. The fixture itself will also act as an alignment constraint while holding the airfoil in place and allowing Exact technicians to capture maximum data on the part without moving or touching the part. A manual or automatic turntable may be used to allow enhanced scanning and registration access to the part.

Scanning

The part is positioned on the rotating table or on a stationary marble top and scanned from multiple perspectives. This procedure is repeated multiple times to provide complete coverage of the part. Known geometric objects, cubes and spheres are often placed in the scene for quality assurance and validation during the validation stage.

The scanner used on these projects is a Breuckmann Stereo 3D Scanning system. This device uses a unique halogen structured white light projection system with dual 6.6 mega-pixel cameras. The scanner is the highest resolution scanner available on the market and was specially built for Exact Metrology in Germany.

Registration

The registration process can be done with or without targets. Both registration methods have different techniques with similar results. Essentially, the targeting procedure uses an automated fitting of point clouds or scan worlds together, based upon three common positions on the part or scene. This process has been simplified with modern software technology. The software will then analyze every point with overlap and run a best fit algorithm over hundreds of iterations to find the tightest and best alignment. The result of this process will yield a fully registered and organized point cloud.

Validation

It is important to verify the automated method with targeting and adding known geometric shapes to the scan. All scans are documented with notes, computer logging and digital photos accompanying the recorded scan setup within the software. A CD copy of all digital data is recorded prior to returning the part or teardown.

MODELING PROCESS:

Once the data is gathered and the registration process is complete, the point cloud or data set can now be worked. The first step is to triangulate or mesh the points together. As part of this early process, points are “intelligently” removed from the network by algorithms in the software. Essentially, the points of redundancy and overlap are decimated and averaged. This mesh is further manipulated by reducing the triangles and points along flatter areas and retaining more triangles in areas of curvature and complexity. This poly mesh can now be exported as a complete *.STL file or similar format.

Surfacing

The process of fitting NURBs and geometry to the poly mesh or point cloud can be a time-consuming and arduous process. A surface is basically draped over the mesh and smoothed to be reflective of the actual part. Once this task is completed and a complete watertight object is created, the model is ready to be exported to nearly any format via various methods. The end file format is entirely up to the client and the limitations of existing conversion tools available today.  A final 3D solid model can be provided as a “dumb solid” with no parametry or history tree as an imported object. The available formats include: Siemens NX, Pro/E Wildfire, AutoCAD, AutoCAD Inventor, SolidWorks, as well as generic formats such as IGES, STEP, ParaSolid (X_T) and others.

Parametric Modeling

The final deliverable is a parametric model. Unlike a solid model, the parametric model possesses relationships of all dimensions within the CAD. With these relationships, the CAD model can be manipulated and fine-tuned without disturbing the overall geometry of the part. For this workpiece, the specific parameters of each cross section within the model can be independently modified without disturbing neighboring cross sections. The end result is a Pro/Engineer CAD model with known geometry that is fully adjustable and possesses a design history.

Exact Metrology Receives Official Certification for AS9100

Exact Metrology proudly announces it has received official AS9100 certification. The Aerospace Standard 9100 includes the requirements for aviation, space and defense organizations.  This certification evidences Exact Metrology practices a Quality Management System (QMS) that consistently meets customer expectations.  Exact Metrology management has been heavily involved with the QMS process. This starts with the setting of Quality Policy, Quality Goals and Objectives. Management Review looks at the data from QMS, sees that Quality Goals are met, sets new ones and strives for continuous improvement. The advantage of this stringent Management Review is that it provides a basis for reviewing goals and performance against goals that are periodically reviewed. As a result, according to company co-founder Dean Solberg, customer satisfaction has increased because, “…the Goals and Objectives of the QMS take the customer’s needs into account and the Exact team can react and plan accordingly.”

Benefits of implementing AS9100 include well defined and documented procedures to improve the consistency of output, quality is constantly measured, procedures ensure corrective action is taken whenever defects occur, reducied overall cost, appreciably lower defect rates and earlier detection, exposure to new markets and retention/increase of market share in existing sectors, internal operational efficiency and overall better process control and workflow.

The company is also ISO9001:2008 certified. This is the only ISO standard that requires certification and is an internationally recognized Quality Management System that governs the sale and service of 3D non-contact and contact measuring equipment for inspection and reverse engineering in the commercial, aerospace, medical, automotive and industrial sectors. The ISO9001:2008 certification highlights the commitment, dedication and service Exact Metrology employs for customers.

Exact is also certified by ITAR, the International Traffic Arms Regulation. As a result, Exact Metrology has a competitive advantage when attracting and retaining defense business. Prime contractors are obligated to comply with ITAR requirements and these same requirements must be employed by subcontractors. Subcontractors such as Exact Metrology, who demonstrate compliance with ITAR standards, are clearly more desirable resources for prime contractors.

Exact Metrology Helps Local Artist Produce Statues for Great American Ballpark

Cincinnati artist Tom Tsuchiya combines his talents with 3D laser scanning from market leader

small_0007_tony-perez-rst-1Cincinnati, Ohio is home to a rich baseball tradition and one young sculptor has combined his creativity with a new, high-performance image scanning technology to create statues for Great American Ballpark, home to the Cincinnati Reds.

In preparing the statues, artist Tom Tsuchiya starts with an approximately 18” high ceramic model. He then supplies the model to the technicians at Exact Metrology’s Cincinnati facility.  Exact is a leading supplier of 3D and CT imaging equipment. They also perform scanning services for numerous manufacturing industries, as well as a diverse assortment of civil engineering, fine arts, commercial and other concerns.  Their subject projects recently included the Fermi Lab particle accelerator, the lions in front of the Chicago Art Institute, a construction site for materials consumption projection, a cross at Our Savior’s Lutheran Church in Hartland, Wisconsin, existing buildings for wiring and ductwork refurbishing, a painting for possible forgery, old sculptures for structural integrity and an actual crime scene for use in the investigation and courtroom proceedings.

smallpeteroseIn this baseball scenario, the scan of the model is prepared as a high-density electronic file with over a million points of information per second captured on the geometry of the proposed statue.  This file is then posted in the cloud and downloaded by a local foundry. The foundry takes the point data and prepares a mold for the statues, which often measure up to 8’ in height.  The brass is poured to produce a statue, then meticulously sculpted by Tom Tsuchiya into his final creation.  As the photos here attest, the statues and plaques made for Reds Hall of Famers Tony Perez, Johnny Bench and others evoked some strong emotions and memories.

Co-Presidents at Exact, Steve Young and Dean Solberg, are big sports fans, so this project was truly a labor of love.  As Young, supervisor of the Cincinnati facility, explains, “We didn’t see a dry eye at the celebration for Tony Perez, a true gentleman and one of the brightest stars in a very crowded sky, that day.”   Joining Perez for this momentous occasion were fellow teammates Johnny Bench, Pete Rose, Joe Morgan and other members from the famous “Big Red Machine” of the 1970’s.

Exact Metrology Uses CT Scanning to Validate E-Lock Wiring Bobbin Postion

Customer needed post-assembly validation of fine wire configuration 

Scans of wire bobbin, showing precise path taken by 0.008” diameter wires inside; scan completed after final assembly of the unit, an inspection process not possible without CT scanning capability

Scans of wire bobbin, showing precise path taken by 0.008” diameter wires inside; scan completed after final assembly of the unit, an inspection process not possible without CT scanning capability

Exact Metrology, working at the company’s Brookfield, Wisconsin location, has successfully used its ProCon industrial CT scanning technology to validate the position of a wire configuration in the bobbin of an electronic lock assembly for one of its customers.

As techician Sean Plastine explains, “A customer came to us to verify the position of a 0.008” diameter wire inside its electronic lock assembly. The position of the wire could not previously be verified while the components of the lock were being assembled. Inspection of the wire bobbin after assembly was also impossible.”

By using its CT scanning technology on the completed lock assembly, Exact technicians were able to determine the wire’s precise position without the need for disassembly or other compromise on the finished article. Any deviation of the wire’s nominal position could be noted, allowing for subsequent changes in the assembly protocol, as needed.

The CT scan clearly shows the path that the wire pair follows inside the lock assembly.

Exact Metrology Holds Tech Expo with 3Dvision Technologies on 3D Scanning & 3D Printing

Product demonstrations and technical presentations from principals impress large crowd at dual open house

On March 17, 2016, Exact Metrology held a tech event in Cincinnati, Ohio with partner company, 3DVision Technologies at both of their offices. Held on St. Patrick’s Day, the event was cleverly titled “Lunch, Learn & Luck,” and had a “March Madness” theme with basketball games playing on multiple widescreen televisions. The event was attended by over 100 people from local area industries, including automotive, aerospace and consumer goods.

Co-Hosted by Steve Young, Exact Metrology co-founder and President, and Todd Majeski, President of 3DVision Technologies, the day included presentations and product demonstrations of the newest products transforming the manufacturing industry in 3D printing and 3D scanning. The informative event provided insight and hands-on experience, while displaying the newest technology that is reshaping the traditional manufacturing process.

The day began at 3D Vision Technologies office, (a provider of engineering solutions & 3D printing for manufacturing companies), with a presentation by Todd Majeski. Majeski discussed the company’s long-term partnership with Exact Metrology, and how both companies work together to improve processes, increase quality, and get their customer’s products to market faster through 3D scanning and reverse engineering. After several presentations and a question-and-answer session, attendees were welcomed into a showcase of 3D printer demonstrations and product displays of printed samples from miniature to lifesize versions, including a skateboard, helmet, and an automotive front grill.

The second part of the tech event was held at Exact Metrology’s office, conveniently located just a short walk away. Participants walked together and, after a St. Patrick’s Day themed lunch, began the afternoon session with a presentation by Steve Young. Young discussed the newest technology in CT (Computed Tomography) scanning systems, which allows users to not only scan the outside of a part, but to actually see inside of it without taking it apart, or damaging the item. Until recently, this technology was used primarily in the medical field but is creating much excitement within a variety of industrial markets now, as it enables manufacturers to check for defects, internal contact points after assembly, porosity and dimensional accuracy, comparing actual scans to point cloud data, CAD files etc. According to Young, this type of 3D scanning has been a “huge success” for his company, which he co-founded with Dean Solberg, who runs the company’s facility in the Milwaukee area.

Products displayed at the event included the P40 Leica Scanner, a long-range scanner, which, according to presenter Jacob Wallace, Processing Engineer at Exact, can be set up and ready to scan in 30 seconds. The scanner has a 150-meter range and will show everything in the surrounding area. Wallace recently scanned an entire office to make an accurate 3D model, complete with windows, doors, ceiling and wall thickness. Other uses of these long-range scanners include collecting topography of roadways (without stopping traffic) and large buildings of 500,000 square ft. or more, to collect information inside and outside of the building, all within a reasonable timeframe.

Inside a Playstation control, possible with the GE vtomex CT ScannerJosh Schradin, QA Manager, demonstrated the GE Vtomex M CT Scanner with a full rendering of a videogame controller he had previously scanned. Attendees were able to see internal components, including the smallest features on the circuit board. He explained how the scan could also be used to find defects or to process for reverse engineering.

Other products displayed and discussed at the expo were the Romer Absolute 77, an Articulated Arm with a Laser Line Scanner, the Atos Triple Scan, the Artec EVA Handheld Portable Scanner and the NDI ScanTrak Large Volume Laser Scanner.

Exact Metrology ended the afternoon with a St. Patrick’s Day raffle, with two lucky attendees winning a 48” high-def television and a MakerBot 3D printer.

Exact Metrology offers a complete line of portable scanning and measurement technologies as well as contract measurement for 3D laser scanning services, reverse engineering services, non-contact inspection, metrology services, 3D digitizing and training.
