3 Surprising Facts about Dimensional Inspection

Posted by Mike Knicker on Nov 30, 2016 2:22:19 PM

 3 Surprising Facts About Dimensional Inspection.jpg

When you think about your daily life the topic of dimensional inspection will likely never come up. In fact, many people could go through their lives not understanding how dimensional inspection works, let alone how it fits into almost every aspect of their daily lives through the products they use. From the coffee cup that you may be holding right now as you read this article to the car you drive (hopefully not while you are reading this article), dimensional inspection was an integral part of the manufacturing process for all of the products you use in your daily life.

What Is Dimensional Inspection?

Simply put, dimensional inspection is the measurement of the distances between different features on a part. If you have a block that is supposed to be one inch long, then dimensional inspection will tell you exactly how long that block actually is. This is a simple case, but think about the intricate measurements required to make sure that each individual part of your car engine will fit together properly in order to move the pistons for you to be able to drive your car.

Even your simple water bottle needs to have very close dimensional measurements in order for the bottle top to screw onto the bottle and provide a tight seal for the water; if the dimensions are not correct then you may have trouble storing the bottle without spilling its contents, or even have an issue trying to fit the lid back onto it once you’ve removed it. This ability of the parts to connect correctly is designed into the dimensions of each part, but dimensional inspection of the individual parts to make sure they meet the design is what ensures the end product will work when it gets to you.

When it is not feasible to measure each dimension on each part, (for instance water bottles would become very expensive), dimensional inspection is used on the tools that make the parts such as injection molding dies that form a water bottle out of molten plastic. If the tool dies are ensured to have the right measurements, then the resulting bottles will be correct; a company can then check a sample product at intervals to make sure that the forming process is working properly as it progresses. So even then dimensional inspection is used on a sample basis.

Dimensional Inspection: 3 Surprising Facts

It should no longer surprise you that dimensional inspection is found throughout the manufacturing processes of almost every product that you use to ensure the safety and integrity of those products, but there are still some facts about dimensional inspection that you might find surprising.

  1. Tight tolerances: Dimensions are never measured to exactly what the design measurement should be (called the nominal dimension) so each design will have a tolerance on the dimension; basically, a stated amount that the dimension can be different from the nominal dimension. So, if you have a measurement that needs to be at one inch, but can be different from this measurement by one-sixteenth of an inch, your tolerance would be +/- (plus or minus) one sixteenth of an inch. In some industries, such as the space industry that builds satellites or parts for the space station these tolerances can be very tight, such as one ten thousandth of an inch (0.0001”) in order for the parts to work reliably in the space environment. This is for the safety of the astronauts or for the reliability of the satellite since you cannot fix a problem once in orbit.

  2. Tighter measurements: A general rule of dimensional inspection is that the dimensional measuring equipment should be ten times better than the tolerance being measured. That means if you are measuring something to the nearest inch your measuring equipment needs to be able to measure to one tenth of an inch. For the above example, if you are measuring to one ten thousandth of an inch (0.0001”) your measuring equipment needs to be accurate to one hundred thousandth of an inch (0.00001”). So, dimensional measurement equipment can be extremely accurate.

  3. Calibration: Equipment for dimensional inspection needs to be checked on a regular basis to make sure that it is still measuring as accurately as it is designed to measure. This verification is done against a very accurate standard part or specimen that has been designed and verified to a certain dimensions and tolerances. By ensuring that the dimensional equipment measures the standard correctly you can be confident that the equipment is functioning properly. Most of these standards are traceable back to the National Institute of Standards and Technology (NIST), which is part of the United States Department of Commerce, but is a non-regulatory agency. NIST is the foremost measurement standards laboratory and is used as the standard for calibrations in most industries.

Dimensional Measurements: In-House or Outsourced

While many companies keep all of the equipment they need to perform all of their dimensional inspections sometimes the equipment is so expensive, and the measurements taken so infrequently, that it makes more sense to have an expert laboratory do the measurements for you. In either case the experts at Q-PLUS are the place to turn for either help on the right equipment to purchase, or the accurate tools to measure your most intricate dimensions and the skilled operators to run that equipment.

Q-PLUS Labs has been a leading dimensional measurement laboratory since 1987; providing one place for precision measurement solutions. As a lab registered to ISO 9001 and accredited to ISO 17025, you can be certain that you will get the right dimensional measurements and calibrations every time.

Nano measurements: 3 basic factors for determining the value of your measurement data

Posted by Mike Knicker on Nov 4, 2016 12:29:05 PM

 Nano measurements 3 basic factors for determining the value of your measurement data3.jpg

With the rapid development of technology comes the greater need for the increased accuracy in measurement capabilities that are able to keep up with the pace of products being manufactured at the nano level. For precise accuracy up to the micrometer, such as 3D measurement data of a needle tip or surface roughness measured to extreme accuracy, nano measurement is the logical solution for these intricate measurements. But how do you know if it is worth your time to invest in this specific measurement solution for your application?

Of course, every measurement technique has its challenges, and with the various methods of nano measurement, there are generally three things to consider when choosing the best method for your application; specifically measurement accuracy, speed, and cost. While there are two main methods of acquiring nano measurement data, optical-based and contact-based, you will need to examine these three basic criteria when you are weighing your decision on which type of method to implement.

Accuracy of measurement

What benefit will this measurement data provide your application? To measure in the nano realm, there are two types of methods. One way is via contact-based methods of nano measurement which can give very high resolution measurements with high accuracy. This is due to the fact that they come in contact with the surface of the part being measured, so that certain features the probe comes in contact with can more easily be distinguish, and thereby measured accurately. However, parts that may become compromised if they come into direct contact with the measuring device would not be suited for this particular form of measurement.

This is only a general rule of thumb, however, as white light interferometry, a type of optical-based measurement, is one of the most accurate methods possible even though it does not come in contact with the measured unit.

Speed of measurement

If you are looking for a faster measurement solution, an optical-based method of nano measurement may be the best option, because this method uses light to take the measurement and does not physically come into contact with the surface that it is measuring. This process speeds up the collection of measurement data without the risk of surface damage, unlike what can be experienced with a probe used in the contact-based methods.

One drawback of these faster methods of measurement may be the loss of some resolution on surfaces with high aspect ratios; such as a surface with features such as steps, slopes, holes or sharp edges. These can be much more accurately measured with a contact-based method, but this will be more time consuming in order to protect the surface of the piece being measured.

Cost to measure

Of course different measurement systems will have different financial costs associated with them, and this will have to be weighed when choosing the right system to meet your needs. When making your decision on accuracy, precision, and speed you will need to keep in mind how much the measurement data will cost. Along these lines, the following are some things to consider:

  1. Will it be more cost efficient to purchase the equipment to perform your measurements in-house; or would it be better to outsource this activity to a lab that specializes in these measurements? If you manufacture a part in-house and need to perform repeated measurements, then it might be in your best interest to invest in the equipment and training necessary to do the measurements yourself.

  2. A major benefit of going to a lab for your measurement needs is the specialization that they have in performing these measurements with the appropriate training, experience and equipment to give you the data you need. Labs are fairly flexible and can be great assets for measurements of one-off parts as well as large ongoing jobs.

While you can make some adjustments to reduce the cost per part, such as reducing the sample frequency of measurements, ensuring that you get exactly the type of measurements for the data you are looking for is one of the best ways to reduce your cost overall.

Nano measurements: Contact-based vs optical-based, which should you choose?

Posted by Mike Knicker on Jul 13, 2016 2:36:31 PM


With advances in the manufacturing of smaller and smaller components, there is a need for measurements at that scale to ensure that best accuracy is maintained. If you require measurement at the nano scale, or one billionth of a meter, then choosing the right technology will be high on your priority list. You want to make the most informed decision when choosing the equipment for measurements that are this important.

In general, there are two different types of nano-measurement technology, contact-based and optical-based. Here is a bit about each type of nano-measurement technology to help you determine which measurement option is the best fit for your application:

How do contact-based nano-measurements work?

1_2D_Image2.jpgAs the name suggests, this type of nano measurement solution will come in contact with the piece to be measured in order to determine its dimensions. The two main types of equipment capable of these measurements are stylus profilometers and the atomic force microscope. Both have been in use for some time and use extremely sensitive styluses to collect the measurement data required.

This type of nano-measurement is ideal if you need to measure a surface with a high aspect ratio since this can be a difficult to accomplish with optical-based solutions. These solutions have been around for a while so they are a tried and true way of measuring, and these methods are practically good at delivering 2-D data.

How do optical-based nano-measurements work?

1_3D_Image2.jpgOptical-based nano-measurement technologies are quickly becoming the go-to devices for measurements at the nano level. Since these techniques do not touch the surface of the piece to be measured, there is no risk that small or delicate parts will be damaged or moved during measurement. As an added feature, optical measurements are also done more quickly than traditional contact-based measurements, and typically have an innate ability to obtain 3D measurements in addition to 2D data.

There are several methods used in optical-based nano-measurement; among them are triangulation, white light interferometry, confocal microscopes and chromatic confocal sensors. The commonality of these methods is the use of light that is emitted and then re-captured in a manner that will allow the equipment to make the extremely accurate measurements necessary to measure at the nano level.

Which type of nano-measurement is right for you?

Each of the methods listed above has benefits and drawbacks that you will need to weigh in your decision; and the decision greatly depends on what you will be measuring. As stated, contact-based measurements can make very high resolution measurements because they come in contact with the surface, but this also risks damage for delicate parts and can be much more expensive to operate.

By contrast, optical-based measurements do not risk damage to parts as only light comes in contact with the pieces, and are capable of measuring much more quickly that the contact-based methods. The drawback can be some difficulty with surfaces with high aspect ratios; such as surfaces with many features such as grooves, sharp edges, holes, steps, steep slopes or channels. So it is important to know what you will be measuring when you are choosing between the nano-measurement equipment available.

Top 7 Applications that Benefit from Nano Measurement

Posted by Mike Knicker on Apr 14, 2015 12:45:00 PM

Top 7 Applications that Benefit from Nano Measurement

The development of new ways to measure objects and surfaces at the nano scale has allowed dimensional inspection providers to improve both accuracy and speed. It has also enabled the measurement of larger samples and objects with different surface types, as well as provide better 3D imaging capability.

Advances in nano measurement are interesting from a scientific perspective, but they also offer practical benefits in a number of different areas.

7 Applications that Benefit from Nano Measurement

Some of the applications that can benefit from better nano measurement include:

  1. Dental - Orthodontic brackets with very small features are difficult to accurately measure with contact probes and vision systems. The use of chromatic confocal technology enables better data collection because stylus size is not an issue, it measures in 3D without contacting the part, and the results are not impacted by reflectivity or translucence.
  2. Forensics - The ability to measure fibers and tool marks with greater accuracy gives forensics professionals better resources when processing evidence. Even specimens without parametric geometry (such as tissue samples) can be modeled in 3D.
  3. Microelectronics - Circuit boards at the micro and nano scale must be measured for quality control to ensure that the conducting path is consistent with specifications and that the wire bonds are correctly oriented. Because the samples are so sensitive, they must not be destroyed during the measurement process, which is why a non-contact system is the best solution.
  4. Medical - Artificial joints, implants, and other medical devices require highly accurate surface geometry to perform at their best. Measuring surface form and roughness at the nano scale ensures that the specifications are met. Nano measurement can also be used in the development and manufacturing of surgical instruments.
  5. Printing - Nano measurement is used to determine the surface roughness of different types of paper. It can also be employed to analyze printing results and detect errors.
  6. Tools and machining - Micro tools and components require a high level of accuracy to operate correctly. Nano measurement can be used for detecting tiny flaws in a micro gear, for measuring form, or for determining the amount of wear on a part.
  7. Material science - The ability to accurately measure a broad range of surface types at the nano scale, without risk of damaging the sample, is a valuable addition to the material science industry. Even materials with differing reflective properties can be measured with the same device.

The list of potential applications goes on and on. Automobiles, injection molding, and plastic films are just a few more examples of the types of industries, processes, and products that can benefit from new nano measurement technologies.

Q-PLUS can help you with your nano measurement needs. We regularly work with businesses in almost every type of industry, so no matter what your application is, we have the experience and expertise you need to get accurate results. Contact us today to schedule your free consultation.

Three Types of 3D Scanning Methods for Non-Contact Nano Measurement

Posted by Mike Knicker on Feb 18, 2015 2:50:00 PM

Three Types of 3D Scanning Methods for Non-Contact Nano Measurement

Dimensional inspection includes many types of scanning devices for a broad range of applications. In the realm of 3D Scanning, the level of detail that can be captured makes it the method of choice, especially for measuring very small objects requiring non-contact measurement methods.

Whereas contact 3D scanners collect measurement data by physically scanning the object with a device that comes into contact with every point on the surface, non-contact 3D Scanners collect immense amounts of data quickly without altering the geometry of the object. This is also an advantage for collecting measurements on the nano scale.

3 Types of Non-Contact 3D Scanning Methods

Laser-Scanning Confocal Microscopes
A confocal microscope uses a process called optical sectioning to collect images from various depths. These images can be reconstructed with a computer to create a 3D model of complex small objects. Unlike other laser systems, a confocal microscope only sees one depth level at a time, which allows it to generate a highly controlled depth of focus for very small objects with tight tolerances.

White Light Interferometry
This non-contact measurement system allows you to obtain surface measurements at the nanometer level. The technology behind white light interferometry uses wave superposition to measure distances based on data collected about reflected wave interactions. Interferometers can also be combined with microscopes to measure very small objects. Because they rely on the detection of waves and not optical images, interferometers are also useful for measuring objects with reflective surfaces.

Chromatic Confocal
Like interferometry, chromatic confocal also uses white light to collect measurement data. However, whereas interferometry uses the superposition of waves after they are reflected off the object, chromatic confocal measures the wavelength as it hits the surface of the object. This method produces more reliable results when measuring surface roughness or step-height depth, due to the minimum mathematical calculation required. The tolerances of large objects may allow the use of a thin whitening spray to facilitate scanning but the geometry of very small objects could be potentially buried by it. Fortunately, all of these methods work well with various types of surfaces from reflective to absorbent.

If you require any of these types of 3D Scanning methods, or if you're not sure what you need, the experts at Q-PLUS Labs are here to help. We'll work closely with you through every step of the process to ensure that you get the best results for your application.

Q-PLUS Labs' Case Study: California State University, Fullerton SAE Race Car Engine Dimensional Analysis

Posted by Mike Knicker on Jan 27, 2015 10:55:00 AM

Q-PLUS Labs Case Study: Race Car Engine

California State University, Fullerton's Society of Automotive Engineers (SAE) chapter chose Q-PLUS Labs to aid them with the challenge to compete in the Formula SAE, a competition which encompasses designing, building, and competing a mini-formula style race car that will be evaluated for its potential as a production item.


chassisFullerton's SAE uses a Yamaha R6 Motorcycle engine, a large displacement choice for the 610cc class. The car's design utilizes the R6 engine as a stressed member to connect the drivetrain to the cockpit. This type of engine design requires the chassis to work with the engine as an active structural element of the chassis to transmit forces and torques, rather than using standard anti-vibration mounts to passively contain it. The R6 engine was chosen based off its high power output and ability to be used as a stressed member. In conjunction with suspension design and tire selection, the engine weight works well to keel the tires while heated under the track's conditions.

Our Process


Because the race car's design is based on the integrity and precision accuracy of the engine's measurements, Fullerton's SAE sought the expertise of Q-PLUS Labs' dimensional inspection engineers. Using a Faro Arm CMM, Q-PLUS Labs provided a dimensional analysis of each mounting point for the engine. These points are integral not only to the race car's design but also to the safety of the driver.

Given the engine's exact 3D measurements, Fullerton's SAE could confidently proceed with their design. They were able to retrofit and reverse engineer the chassis to properly fit onto the race car's engine. Currently in the manufacturing stage process, in a few months they will produce the assembled chassis to compete in the Formula SAE® Lincoln this June.

What to Look for in a Dimensional Measurement Facility

Posted by Mike Knicker on Jul 29, 2014 10:00:00 AM


Hiring a dimensional measurement provider can be a daunting task, especially if you are not well versed in the various techniques that are employed in the industry. What type of measurement techniques should be used for your application? What tolerances are acceptable? What is a reasonable turnaround time for your project?

All of these questions and more can be answered by a qualified provider that offers excellent service.

What to Look for in a Dimensional Inspection Lab

Everybody has different dimensional inspection priorities. Whether you are on a tight budget, face a quick deadline, or have a particularly challenging application, working with a provider that can reliably meet your needs is important.

  • Modern equipment - Although the field of dimensional measurement has existed since the first standardized measuring tools were created, the technology is constantly evolving. A facility that doesn't stay on the cutting edge of 3D scanning technology and all the other measurement methods may not be able to provide the most efficient and accurate service. Look for a lab that regularly updates its equipment inventory so that you can get the best service now and in the future.
  • ISO 17025 accreditation - An ISO 17025-accredited lab must meet certain quality standards so that you can be confident that your project will get the attention it deserves. ISO 17025 accreditation meets and exceeds the requirements of ISO 9001. Although many dimensional measurement facilities achieve ISO 9001 registration, not as many make the extra effort for ISO 17025 accreditation.
  • Prompt service - Some dimensional measurement services can't happen overnight, but you should be able to communicate with your provider as often as necessary. Look for a lab that responds quickly to your inquiries and has the flexibility and capacity to provide rush services if you need them.
  • Qualified employees - Dimensional measurement requires both training and experience. Make sure your provider is staffed with technicians who have the level of expertise required for your application. You should also look for a lab that offers the flexibility of on-site measurement and training so you can get the services you need, where you need them.

5 Predictions for the Future of Dimensional Inspection

Posted by Mike Knicker on Dec 1, 2013 10:38:42 AM


Although the principles and science of metrology have not changed, the world of dimensional inspection is always evolving. Advances in technology and a changing political landscape will influence the direction of the industry and play a role in the technology available to manufacturers. Preparing for these changes can help ensure that manufacturers can be confident that metrology labs provide the best service possible.

5 Predictions for the Future of Dimensional Inspection

1. There will be an increase in the use of 3D scanning.
Of all the technologies used in dimensional inspection, 3D scanning is one of the least mature despite how long it has existed. However, it is a proven technology that is rapidly becoming more widely known and accepted. Although 3D scanning is not likely to make other technologies obsolete, it is quickly becoming an essential tool for manufacturers that need dimensional inspection.

2. The United States will need more dimensional inspection capability.
Globalization has changed the manufacturing industry in the United States, but the pendulum is swinging back. According to the
Bureau of Labor Statistics, U.S. employment in the manufacturing sector has been steadily on the rise since 2010. Several factors contribute to the shift that is starting to occur:

  • Labor rates are increasing in China, bringing manufacturing back to the U.S.
  • Quality concerns are driving manufacturers to desire more control over manufacturing processes and quality.
  • Shipping times influence where a product is manufactured.
  • Strides in automation have made manufacturing in the U.S. more affordable.
  • The U.S. economy is gradually improving. 

3. More engineers will be required to provide these services.
The trend toward bringing manufacturing back to the United States means more metrology services will be required, which means that more engineers will be needed to perform these services. This increase in demand translates into more metrology courses at universities and better technical facilities for students. The end result for manufacturers is a larger pool of talent with better dimensional inspection skills.

4. Accuracy requirements will become increasingly more stringent.
As technology evolves, regulatory and quality requirements have become more and more stringent. This trend is only expected to continue, which means working with a provider that can meet increasingly high standards will be more important than ever for manufacturers.

5. New technology will continue to be introduced to the industry.
New technologies from the private sector will continue to be adapted and adopted by dimensional inspection departments and providers. These technologies are expected to be better, faster, and more cost-effective. Some of this technology will be bold and game-changing. 

What does all of this mean for people performing dimensional inspection? We must be prepared to adapt to the changing landscape by being open to new technologies, by supporting the educational institutions that will produce the next generation of engineers, and by ensuring that we have the capacity to respond to the increasing demand and complexity in the industry.

What do these predictions mean for manufacturers? You want a lab that has their finger on the pulse of the industry. Talk to your metrology provider about their approach to new technologies and the changing landscape of dimensional inspection. No matter what happens to the industry in the future, Q-PLUS Labs is committed to staying on the cutting edge of dimensional inspection.
