Scanning for Engineering and CNC

The world is a better place in the one-off part business. With new technologies, better scanners (both arms and 3D scanners), and smarter software – we now have an efficient and cost-effective way to scan items directly into CNC machines for engineering.

Consider this Scanning for CNC Issue:

Discontinued parts for 3D scanning and CNC

How do you take a discontinued part and create a duplicate of it?

Or, how do you create several copies of that same part?

Think of the first step in the Reverse Engineering process.

In the past, this has been an expensive, slow, and inaccurate process.

Today’s Solution: Scanning for Engineering & CNC

Hexagon TIGO SF CMM 3D Scanning Station

Step 1:  Generate a Point Cloud


of the Part or Object

There are two main approaches:
1) Arms with sensors attached, that can touch or scan any position on that part that you can see
2) 3D scanning.

Mitutoyo CMM machine 3D Scan Station

Types of CMM Machines

CMM machines start at $ 5-10,000 and can easily hit $ 130,000 or more depending upon the size and accuracy requirements.

Vendors like Mitutoyo, Hexagon and Zeiss are serious vendors in the CMM marketplace. 

At best CMM machines can capture about 500mm per second.

Zeiss MMZ G CMM 3D Scanner

zCat Portable 3D Scanner

The zCAT 3D scanner is targeted at shop-floor measurement. it costs about $40,000.  

Most significant shop-floor measurement innovations have been either portable, or probing systems built into CNC machine tools—also known as on-machine verification or OMV.

The zCAT advances the technology of portable measuring arms by automating repetitive part measurement with significantly better accuracy.

zCAT comes with a five-hour lithium-ion battery.  It needs no electrical connection, therefor has no cables to stumble over. Another benefit is that zCAT doesn’t use air bearings, so there are no air hoses underfoot.

Arm Scanning with CMM

Arms with CMM have been the industry standard for years.  They are mostly accurate and stable.

One advantage of arm scanners is that you can be very selective as to what section you wish to have tooled. 

Think of a specific fitting / opening you need to mimic or fit to. 

3D Scanning with Faro Scanner

With these types of scanners, you have the ability to capture specific sections.

Faro arm scanners are the industry standard and market leader here.

Handheld 3D Scanners

This category of scanners is much more affordable, quick and accurate. 

With the passing of a laser scan, we can quickly and accurately capture the surface data of that part or object. 

It might take several swipes/scans of that object to capture it in its entirety, but this scan will be worth its weight in gold. 

artec-leo-2

Good industry handheld 3D scanners are are priced approximately $10-30,000.

We sell and use Artec hand helds, but Creoform are also excellent in this class.

The new Artec Leo can capture millions of points a second, which is rated at 80 frames per second.

Another huge benefit of the newer class of hand held scanners is portability. These hand held scanners can be run from a laptop.

Creoform White Light Hand Held 3D Scanner

Step 2- Point Cloud Data Assembly Required

3D Scanning with Point Cloud Generation and Assembly

 

What most suppliers tend to gloss over is the assembly of these new point clouds. 

A point cloud is nothing more than a zillion 3D points in space that look like your part. 

The wonderful news about this process is, software is now smart enough to greatly assist us in this automated assembly. 

Point Cloud Density and Sub Density Map Piping

 

This results in a huge increase in productivity than the past.

In the past we had to use markers – targets, so a scanner knew when the next scan section starts and stops; along with knowing what to assemble to.  

With small parts you can assemble the scan sections in just a few minutes, but on large buildings it can take 10-20 hours of computer processing.

Step 3- Turn Point Cloud into a Mesh

CAD Mesh of a Part

Now that we have an assembled and clean point cloud.  It is almost ready to turn it over to the CNC machine. 

But we must now turn that clean and assembled point cloud into a mesh – a surface. 

Some 3D scanning vendors include this feature, but most production houses use a higher end version called GeoMagic Wrap for this task. 

Here we can smooth out surfaces, define how tight we want the mesh to be, check for hot-spots and inconsistencies, and even provide quality control across multiple parts to make sure they are within the production specifications.

geomagic turbine design

Here we generally output to a generic *.stl file, but HOPS files are also suitable for most NC machines.

At this stage, these are not CAD Files yet, but clean, mesh point cloud files.

Except for cleaning up a mesh, you really don’t edit these mesh files very much. 

Within reason, it is a WYSWIG type file.

the good the bad and the ugly

The Good, The Bad and The Ugly

Further down the page we will discuss building a full CAD model. CAD modeling is useful if you are going to modify or edit a part.

For a straight forward scan to print or CNC approach, you don’t need that.  You just need to make a copy of something.

At this point we can now simply drop the *.stl file into https://www.cadcam.org/3d-cad-services/3d-printing-2/, get an instant quote, and directly print this for you in a day or two.

Or, you are now ready for your CNC machine and MasterCAM software.

Don’t underestimate the fact, that some assembly will be required for your part. 

You would be amazed how often we see missing sections of your part / object that where missed during the actual scan. 

How can your CNC machine, even try to machine something that is undefined?

On a recent project– we cleaned up a huge mesh file on a very large building.   The point cloud contained ½ billion points. 

Taking all of this into account, you truly get what you pay for.

Don’t expect a $ 3,000 approach to create Aerospace accurate parts.  It won’t happen.

Industrial quality 3D scanners with good quality software are a $ 30-50,000 investment.

The industry leader RX Solutions DeskTom/EasyTom/EasyTom XL and all the way up to the UltraTom range in price from $ 100,000 to $ 1m systems.

The better scanners give you a better product.  We utilize two RX Solutions CT scanners for our 3D scanning.

 

The Solution

In our business, one size does not fit all.  We have learned our lesson with cheaper, less production arms and scanners. 

We have also developed a clean process to make sure we know how to scan all of your surfaces, without missing any data. 

aluminum 3D scanning

On shinny parts like aluminum, we often have to spray them with an anti-glare (3D Scan Spray) to reduce the gloss.

Otherwise, the scanners laser light would reflect off the surface. 

Don’t worry, it is temporary and only useful for about an hour!

Faro Focus 3D Measurement & Imaging

 

CAD/ CAM Services utilizes CMM, CMM arms, and high-end 3D laser scanners, including some with white or blue light. 

 

 

Industrial CT Scanner

We also utilize two types of industrial CT scanners to capture your meteorology and surface data. 

This even allows us to look inside of your objects for voids, and surfaces you cannot see from an outside appearance. 

FARO-Focus-M70-Laser Scanner- Scanning Pipes

All of our software is current, with experienced staff who knows how to operate it for excellent results.

3D scanning can be a science.  It is something you learn with practice.

What is a 3D CNC Scanner?

Scanners of this type allow you to recreate the correctness of the digitized part, which occurs by measuring the geometry of specific parts. It immediately provides an answer to the question: "Does the new component correspond to the original parameters of the product?". Such control of the manufactured goods reduces the risk of defective items. And also to minimize inaccuracies in the sizes.

The device helps to reproduce complex details. Even if they are sold manually from soft raw materials (plasticine is a good example). A similar method is actively used in the production of various decor. More responsible tasks lie ahead for industrial 3D scanners for CNC. Models of this configuration are distinguished by the accuracy and speed of their scanning.

performance characteristics

Sensors built into CNC scanners have the following performance characteristics:

  • measurement from 5 to 1200 millimeters;
  • maximum value measurement frequency 16150 Hz.

Digital interfaces are:

  • Virtual COM port.
  • Ethernet 100 Mb.
  • RS232 and RS485.
  • CAN 2.0A, 2.0B.

Analog inputs for programming:

  • .5mA (load ≤ 2800Ω)
  • .10mA (Load ≤ 1400Ω)
  • .20mA (Load ≤ 700Ω)
  • .20mA (Load ≤ 700Ω)

And the following characteristics are also provided:

  • several modes of data buffering, namely by synchronizing signal or time;
  • built-in buffer for storing up to 40 thousand measurements;
  • it is possible to connect positioning signals for up to two axes;
  • has four galvanic inputs and two outputs;
  • many models are IP67 rated;
  • supply voltage is five volts;
  • stepper motor signal buffering is present.

Construction

With regard to construction, this device is divided into three subsections. They differ in the specifics of the mechanism and are expressed in the following forms:

  • System with fixed components. And also with high precision angle type sensor. The measuring arm is positioned at the end, providing mathematical calculations that are directly related to the rotation of the wrist. Suitable for probing interior or recessed spaces with several small inlets.
  • Inside the carriage is a perpendicular measuring arm. During the sliding of the hand on the carriage, axial displacement occurs. The optimal system is used for convex curves or flat surfaces.
  • The third form implies a combination of the two above. So the manipulator is combined with the carriage. Allows you to get more voluminous and large-scale objects that have internal planes. Or overlap one another with a surface.

Applications

The use of the 3D CNC scanner is spreading across multiple industries at the same time. Professional equipment belongs to different fields of activity: science, business, medicine, production and design. The following usage solutions are common:

  • Automotive. Designing cars or motorcycles. Their repair and tuning.
  • Architecture. Scanning entire buildings, facades or individual rooms.
  • Media sphere, advertising and design. Allows you to produce the kind of material. Develop graphics for advertising or design.
  • Dentistry, medicine. Precise scanning of various parts of the body. Preparation of prostheses and dental implants.
  • Oil and gas industry. Monitoring the wear of a pipe system or scanning areas for their laying.
  • Science and education. Solving various problems for educational purposes. Scientific measurements, preparation of constructors and designers to work with large design tasks.
  • Industry. production tasks. Design development. Quality control of manufactured products. Precise control over the dimensions of components. More simplified assembly of overall equipment and mechanisms.
  • Engineering. Accurate marking for further design and preparation of design documentation for production work.

Step by step installation instructions

  1. Sensor installation. On the machine, you need to install the sensor so that it has the ability to move simultaneously on two axes. They must be mutually perpendicular. More often this is the situation with the X and Y axes.
  2. Connecting the sensor to the machine. There are two options for this step. The first involves working with signals on the CNC controller. The second works with quadrature axes A and B.
  3. Power connection. Cheaper modifications are powered exclusively from the USB port. Industrial sensors can be provided not only by this. But also the power supply. Moreover, power sensors have a voltage of up to five volts. It is also possible to consider the option of a galvanically isolated sensor power supply (9–36 volts).
  4. Connect the sensor to the computer. To scan qualitatively, connect the sensor together with the USB virtual COM port. You can also use the Ethernet port. The latter option has the advantage of a higher exchange rate. For USB, the advantage is that there is no need for an external power supply. But the cable length will need at least five meters, according to the USB specification.
  5. Establish communication with the encoder. Run the installed program and confirm the connection with the "Connect" button. After that, you can go to the connection settings by selecting the "RS232/RS485/USB" tab. This is important for those wishing to work via aorta COM or USB. You can also select "Ethernet" if you plan to operate via Ethernet.

    • Currently, few people are not familiar with such a concept as 3D printing. Many companies are using modern 3D printers with might and main, recreating layouts of various shapes and sizes with their help. There are also those that recreate whole objects - not only small ones (for example, phone cases, souvenirs, sneakers), but also large ones (houses, engine parts, etc.). But all this would not be possible without 3D scanners. It is they who allow you to accurately copy almost anything - from huge buildings and structures to humans, animals, small objects and much more.

    What is 3D scanning and what is it used for

    Three-dimensional scanning is a technology that appeared in the 60s of the 20th century. It was created in order to transfer the physical parameters of the object into a digital format in the form of a three-dimensional model. The need for this naturally arose when people around the world increasingly began to use computers both in everyday life and in production.

    The first samples of 3D scanners were quite simple and did not have wide functionality. Gradually, they became more complex and improved, making it possible to achieve an ever clearer image of the object. This has become especially relevant with the advent of lasers.


    3D scanners allow you to transfer object data into digital format

    3D scanning has opened up new opportunities in various areas of human activity - from the automotive industry and the military industry to design, medicine and cinema.

    How a 3D scanner works

    A 3D scanner is a device that examines an object by digitizing it using sensors and using the information received to create a three-dimensional model. In fact, a 3D scanner creates a digital copy of a physical object of any configuration and complexity. In this, it fundamentally differs from its predecessors - conventional scanners that can only read information from documents and photos.

    The scanning process itself can take place in different ways - depending on the type of 3D device and the technology used, as well as on what object you want to process with it - moving or static.

    3D Scanning Technologies

    There are 2 main types of 3D scanners - laser and optical. Their fundamental difference lies in how and with the help of what the “removal” of data takes place. Let's take a closer look at both.

    Laser 3D scanning, as the name implies, uses a laser and can be carried out both at short and long distances from the object.


    Laser scanner

    For the most part, 3D laser scanners work on the principle of triangulation, when the camera finds a beam on the surface of an object and measures the distance to it, after which a cloud of points is created, each of which has its own coordinates in space, and a 3D model is built. Their "advantages" are affordable price and ease of use combined with high scanning accuracy. Of the "minuses" - there are restrictions on the remoteness and size of the object.

    Another type of laser scanner works by measuring the response time of a beam from the surface of an object - the so-called laser range finder. They are widely used where it is necessary to create 3D models of various buildings and structures. It is not advisable to use them at short distances, since in such cases the response time is very short and the accuracy of the data is reduced. Otherwise, this type of scanner is characterized by high scanning speed and the ability to read all the details.

    The disadvantage of laser scanners is the impossibility of their use on moving objects. Then optical 3D scanners come to the rescue, which shoot with one or more cameras from different angles an object illuminated by a special projector. Based on the received image, a three-dimensional image is built.


    Optical scanner

    A "contraindication" for the use of this technology are reflective and translucent surfaces - shiny, mirror or transparent. But when scanning a person, they are simply irreplaceable.

    3D scanning methods

    Any object can be digitized both by contact and non-contact methods. In the first case, active interaction with the subject is necessary, in the second, accordingly, no. Both of these methods have their advantages and disadvantages.

    Contact 3D scanners

    They have a mechanical probe with a special sensor that measures parameters and transmits the collected information to the device. To do this, the object under study is placed on a special surface and fixed (if necessary). Such tight physical contact makes it possible to determine and then build a 3D image as accurately as possible, however, there is a small risk of damage to the prototype.

    Non-contact 3D scanners

    This category includes all devices capable of scanning at a distance. This is especially true for objects located in hard-to-reach places.


    Non-contact 3D scanner

    A stream of radiation (it can be ultrasound, light, X-rays or a laser) is directed to the object and reflected from it, it is recognized by the 3D scanner. They are similar in principle to a video camera and may require the use of additional devices for better lighting.

    Non-contact 3D scanners come in 2 types:

    • Active - work with the help of a laser beam or structured light directed at an object, which, when reflected, give information about the location of the object in the form of coordinates.

    • Passive - use time-of-flight rangefinders that read the time and distance that the laser beam travels to the object, and so - for each point in space, which ultimately allows you to accurately recreate its three-dimensional image.

    Desktop 3D scanners are very popular and widespread, since they are mostly simple and safe to use, do not require any special technical skills and are quite cheap. The EinScan-SE 3D scanner is one such example. It can be used both at home and in the office. It has access to the API of many popular 3D printers, which makes it possible to immediately print the created three-dimensional model.

    Types of 3D scanners according to the principle of use

    There is also a variety of species here. Let's highlight the main ones:

    • Manual: The are handy and simple models that are easy to use as they are quite compact and do not require special skills. True, their technical capabilities may be somewhat limited.

    • Portable: The is mainly used for field work and is convenient to take with you.

    • Desktop: have extended functionality and are used to create high-quality 3D models. Most often used in offices.

    • Stationary: are used, as a rule, in production, various enterprises, as they can scan a large number of objects of the same type at once. Mounted on special turntables.


    Handheld 3D Scanner Calibry

    Such a choice of products allows you to select the right model for a specific task. In some cases, scanners independently measure objects, in others - with the help of a person who sequentially moves the device until all the necessary information is collected.

    Such options for hand-held 3D scanners as Calibry are in high demand among buyers. Despite the apparent simplicity of execution, it has a high resolution and scanning accuracy, due to which it is able to digitize objects with a length of 0.2 to 10 meters. Objects that have a non-standard surface - dark or shiny, with a large number of corners and small details will not become a problem either. Among other things, its undoubted advantage is its low weight, only 900 grams.

    Advantages and disadvantages of 3D scanners

    Surely, many of the potential buyers are wondering: do you really need a 3D scanner to invest a lot of money in it? What can this acquisition give and will such an investment be justified?


    3D scanning has become an integral part of any modern manufacturing process

    In order to understand how much you need this equipment, we will list its advantages and disadvantages.

    Benefits:

    • They make it possible to scan objects located at a remote distance and in places inaccessible to the presence.

    • They have the ability to "read" not only colors and images, but also to convey the texture of the surface.

    • Significantly speed up the process of "taking" data from any object, even a very complex one with a large number of planes.

    • A variety of models allows you to choose the most convenient version of the scanner, including manual or portable, which can be easily taken with you.

    Weaknesses:

    • Some scanners are unable to recognize transparent or black and white objects. In this case, their preliminary preparation (treatment with a special composition) is required.

    • I do not always display complex objects correctly, with a large number of inserts and partitions.

    • To obtain a high-quality result, they require skills and abilities to work with certain computer programs for creating 3D models.

    • If the rules of operation are constantly violated, it may become necessary for expensive repairs to the equipment.

    If you need high-precision and high-quality three-dimensional copies of objects, then you cannot do without a 3D scanner. It makes it possible to work in almost any conditions - indoors and outdoors, and with any objects by type and size. It is not surprising that now these devices are in great demand, which gives rise to the annual release of a large number of models, from which you can always choose the one that suits you in terms of quality and price.

    Things to consider when choosing a 3D scanner

    The computer equipment market offers a huge amount of all kinds of equipment, including devices for three-dimensional scanning. Navigating that variety is sometimes not at all easy: some buyers are only concerned about the cost, others are interested in the number of options (sometimes completely useless), but the most far-sighted look at the ratio of the first and second.


    Choosing the right 3D scanner is a big deal

    It is not always easy to take into account all the technical points that can significantly affect what result will be ultimately achieved. We will tell you what you should pay attention to if you are thinking about buying a 3D scanner.

    Focus on the following parameters:

    • How high is the accuracy of the 3D scanner. This is one of the most important features. It needs to be targeted first.

    • Resolution also plays an important role. It follows from the first, since the accuracy of measurements and the quality of copying depend on the resolution.

    • In what range the device operates, how close / far it can be from the scanned object.

    • The scanning field is the parameters of that object, thing that it is able to process in 1 session.

    • Does the scanner capture various atypical types of surfaces with complex terrain - channels, partitions, holes, etc.).

    • Portability, mobility of the device - how easy it can be moved if desired, taken with you, its size.

    • The time it takes to prepare for work, as well as the duration of the digitization process itself.

    • The range of possibilities in terms of copying: are there any restrictions on shapes, textures, material, as well as operating conditions - temperature, light, etc.

    Of course, the better the quality of the 3D scanner, the more expensive it is. However, you should focus primarily on the tasks that you face, and only then take into account everything else.

    Applications

    Three-dimensional scanners are in demand in many areas of human life. They are irreplaceable both in the industry, and for household needs. The range of their application is so wide that it is possible to list for a very long time. It's easier to say where they are not needed.

    The most common areas of use are, of course, medicine, industry, architecture, construction, film industry and design.

    For example, in dentistry, these devices allow you to create ultra-precise three-dimensional models of dentures. One type of such a scanner is Shining 3D's AutoScan DS-EX PRO, which does a great job with a variety of tasks while being quite affordable and reliable.

    Medical 3D Scanner

    In engineering, such technologies are also indispensable. Digital building prototypes are now much easier and faster to obtain than in the past, when it required multiple manual measurements and then entered into a database. Any physical object can now be recreated in three-dimensional form, moreover, in the shortest possible time and with a minimum error.

    In cinemas, we can see with our own eyes "revived" fantastic characters, which were created using motion capture technology, which made them as realistic and impressive as possible. This would not have been possible without 3D scanners.

    A few decades ago, it was even difficult to imagine all the things that we use all the time today. And in many ways this has become achievable thanks to three-dimensional digitization. This approach provides huge advantages in work (especially for technical specialists - engineers, designers, designers), however, in order to use them to the maximum, it is also necessary to understand computer programs for 3D scanning.
