  • One Probe to Rule Them all

    Unlike our friends in the "Lord of the Rings" Middle Earth, there is no metrology or CMM solution to ‘rule them all” for every customer’s different requirements, and that’s a good thing! Imagine if you were forced to measure turbine blades with high throughput and accuracy requirements using a fixed-axis scanning probe instead of a CORE Machine or REVO?

    Or what if small-businesses budgeted for a REVO system when they only required a simple touch trigger inspection on their open toleranced castings? It’s clear that being able to provide multiple solutions for any given situation is critical to success. Luckily, that principle is exactly the foundation that Wenzel has been built on. So let’s take a look at the three top options for probing on your Wenzel CMM.

    PH-20

    The PH20 is a great 5-axis probing option for customers who are concerned about high accuracy, throughput and cost. The PH20 uses head motion technology that minimise errors found in traditional touch-trigger machines that require moving all three CMM axis to take points. Throughput is increased with features such as inferred calibration and infinite 5-axis positioning which removes the need for time spent indexing the head.

    PH10 with SP25

    The PH10 head is a utilitarian motorized probe head that provides the base for multiple configurations of probe modules, touch trigger, scanning, and even our Wenzel Shapetracer 2 or Phoenix heads. The PH10/SP25 probe configuration enables scanning capabilities for your CMM. Using 5 different available modules, the SP25 is a 2 in 1 system for scanning and touch trigger point collection. Why scan you ask? Scanning a prismatic feature quickly provides the most information (points) for form and profile data. More data collected equals more confidence in your measurements to validate your process.

    REVO-2

    The REVO probing system is a multi-sensor 5-axis measurement system. Multiple probe modules,(even including Surface Finish and a vision system) combine with the Renishaw UCCS5 controller to provide an inspection system unlike any other. It’s uniquely synchronized 5-axis technology combines the 2-axis head movements with the CMM frames’ XYZ axis movements to minimize the effects of CMM motion at high measurement speeds – the REVO head handles the fast motions, while the stable granite frame moves in a slow and controlled fashion.

    Throughput is greatly increased through calibration procedures and the utilization of 5-axis inspection programming. In some cases we’ve seen traditional 3-axis touch trigger inspection times reduced from over an hour – to minutes. A great addition to any Wenzel CMM, the REVO probing system is a must have for engine blocks or complex housings, blade inspection, or anyone looking to increase their quality department throughput.

  • X-Ray Vision

    Growing up, I always wished to have super powers like I saw in the movies. However, I spent more time trying to pick one then I did thinking about what I’d actually do with it. Time travel, invisibility, teleportation, flying, telepathy; how could I pick just one? Well it wasn’t until recent that I realized I get to work with a super power every day and that’s X-ray vision!

    Superman has nothing on this x-ray vision though. While he could see through objects, our CT scanners up the ante, and can generate a 3D volume from the individual 2D x-ray projections that are taken during the scanning process. This 3D volume is what makes CT scanners such a powerful tool. With the 3D volume, you can create an STL file for 3D comparisons to CAD or use it for another form of inspection called NDT.

    With NDT or non-destructive testing, we are able to scan entire assembled parts that have intricate inner workings and see exactly what is happening inside them. This gives manufactures the ability to pin-point defects in assemblies without opening them up and potentially destroying the cause of the defect or the part itself. Once we have a part scanned, we can section through the scan volume in 2D or 3D to find defects or to see how individual parts are mating together inside. No more having to guess what’s wrong inside your part.

    NDT is especially useful for inspecting circuit boards, electrical connectors and assemblies, key fobs, valves, perfume bottles, motors, etc. Over the years as a CT Technician, I have seen my fair share of unique parts that have benefited from CT scanning and NDT. Our customers are always amazed at what they take away from our online sessions where we are able to review the scan data and work on finding the cause of their problems together.

  • What Makes A Wenzel A Wenzel (Part 2)

    Wenzel recently celebrated it's 40th year. So what is it that makes a Wenzel a Wenzel? No compromises by Wenzel on materials; inherent precision; build quality and performance. That's what has helped Wenzel grow into one of the top CMM manufacturers in the world.

    In part two of our profile on Wenzel we take a look at Wenzel's choice to not compromise on granite thickness.

    Metrological and Physical Performance

    Granite is an expensive raw material and expensive to process. It's also expensive to ship due to its weight and so over the years CMM manufacturers have used less granite in its CMM base plates to save both material and shipping costs. But at what cost to the customer?

     

    Look at the granite base thickness on this 25+ year veteran Renault-Federal CMM that's still in daily use at a Wenzel customer location. The Renault designers obviously knew the role the granite plate has in creating a stable CMM platform. What Changed!

    Weigh the Competition – They’ve Been on a Diet!

    Compare the gross weight of a Wenzel LH CMM with the equivalent competitors size machine and you will surely notice the huge difference. Check it out!

    Wenzel CMMs are engineered to last a lifetime with a significant dollars per Kg price ratio advantage. Do the math. If Granite is only 3% heavier than aluminum, as we mentioned before, what else are their CMMs missing?

    Granite Bends?

    The top surface of a CMM table is subjected to lights and other temperature influences while the underneath surface is protected by base covers and is generally in the dark. What influence does only a 0.5 °C temperature differential between top and bottom surface have on CMM accuracy?

    • The result depends on plate thickness.
    • From the above table we can see that even just a 0.5 degree plate temperature differential can cause a 5 micron deflection; while even Wenzel has had to comprise its plate thicknesses to remain competitive its granite plates remain the thickest in the industry.
    • Typically a Wenzel plate is 30% thicker than the competition.

    First Among Equals

    All CMM specification sheets state a maximum part weight; this is NOT the weight under which the plate will fracture but the maximum weight than can be supported with no CMM accuracy degradation.

    We have witnessed the trend from some CMM manufacturers to reduce considerably their granite plate thickness over past years to reduce costs. So then how does one manufacturer with a thinner CMM plate have a higher quoted table loading than another with a thicker plate! Science or Marketing?

    Let's apply a 6000Kg load to a 8.10.7 plate supported over 1000mm and look at the calculated bending moment.

    From the above table we can see that the thickness of the plate is critical to minimizing the deflection due to table loading and that competitors claims are exaggerated by their marketing departments in the knowledge that most customers CMMs rarely measure components that come close to the quoted maximum part weight.

    Wenzel is still producing CMMs that perform to quoted specification and have been designed for competitive manufacturing without compromising on the "hidden" performance factors.

  • What Makes A Wenzel A Wenzel (Part 1)

    Wenzel recently celebrated it's 40th year. So what is it that makes a Wenzel a Wenzel? No compromises by Wenzel on materials; inherent precision; build quality and performance. That's what has helped Wenzel grow into one of the top CMM manufacturers in the world.

    In part one of our profile on Wenzel we take a look at Wenzel's choice to not compromise on granite.

    Uncompromising Use of Black Impala Granite

    The Wenzel LH range of bridge-style Coordinate Measuring Machines are manufactured from granite; the proven metrology material provides for stability, accuracy and long life performance.

    Wenzel is a true CMM manufacturer; not just an assembly shop for outsourced parts typical of today's CMM supply industry. The Black Impala South African granite used is renowned for its superior qualities of improved stiffness, less porosity and a 50% improved resistance to humidity over the more commonly used Chinese black granite.

    The Impala granite comes to Wenzel's Wiesthal, Germany manufacturing facility from the Wenzel granite works in South Africa. The company has specialized in granite cutting and machining operations for over 70 years.

    Final granite grinding and hand-lapping takes place at the main headquarters in Germany. No other CMM company is responsible for its own granite production; the base of a CMM‟s performance.

    Aluminum is Only 3% Lighter Than Granite

    The investment by Wenzel in the very best CNC Grinding Machines ensures granite components are produced to outstanding straightness and flatness specifications thereby minimizing the final hand-lapping process. All granite CMM motion components are core drilled before grinding to remove as much mass as possible ensuring the Wenzel all-granite CMM structure has competitive measuring performances when compared to the lighter, thin-walled, aluminum framed CMMs offered by many competitors.

    Born to Scan - Granite, the Structure of Choice

    The all black Impala Granite Wenzel CMM range was developed using finite element analysis techniques and was born as a scanning CMM; the demands on scanning CMM structures are far more than requested for a simple touch probe application.

    Rigidity and stiffness with minimum deformation are necessary due to the acceleration forces exerted by continuous motion scanning and the ever changing CMM motion directions.

    All-granite CMM structures are renowned for their stiffness and are the structure of choice by all manufacturers for their ultra high performance scanning CMMs. Granite offers the perfect scanning platform when compared to the far less rigid aluminum framed CMMs.

    Don't Settle for a B Grade. Get an A!

    All Wenzel LH machines come standard with a granite base hand lapped, to AA surface plate standard, and with a plate thickness second to none in the industry. The stability of all bridge CMMs comes from the surface plate; economic pressures over the past decade has caused manufacturers to "thin" plates dramatically and no longer lap the granite table to surface-plate flatness standards. Not Wenzel.

    Wenzel does not compromise product quality and engineering integrity to maximize profit margins. While some competitors even measure the deformation of their thin granite plates and attempt to compensate for deformation with software, Wenzel just uses sound and proven engineering practices up front to manufacture its ultra stable CMMs!

  • Why Manufacturing Companies Can’t Risk Not Using Computed Tomography

    Computed Tomography or CT, as it’s commonly known, has been around for a few years. Most people are aware of CT technology when applied in the medical world. Now Industrial CT machines apply it to manufacturing as well and offer added "Product DNA" protection. 

    Medical CT machines take multiple x-ray slices through human bodies so doctors can get a complete 3D image of the person’s medical issue. The completeness and the clarity of information available to doctors today is amazing compared to looking and probing patients just from the outside when compared to just a few years ago.

    •  A modern CT system can measure parts inside and out. 

    •  A modern CT system can measure assemblies and see why they don’t work or  go together very well.   

    •  A modern CT can measure multi-material assemblies and isolate the individual components if they have a different density and it can even analyze the material flow in plastic and composite parts.

    Industrial CT offers the same huge step forward when compared to engineers trying to understand what is wrong with a component or assembly when just being able to probe from the outside only. One important difference between the medical and Industrial CT machines, like those produced by Wenzel, is that we add a much higher degree of dimensional accuracy to the images.

    CT System Capabilities

    A CT machines can look at the inside of a part in extensive detail as well as the outside, but relative to CMM’s or other devices they are quite expensive and the volume of machines sold is still extremely low. Why is this if CT can offer so much?

    Firstly, it is a matter of awareness. Are you familiar with the capabilities of a modern CT system like those made by Wenzel?

     

    View showing a wall thickness analysis of a fountain cup lid. This is vital to plastics molders to ensure that they meet the product specification with the minimum amount of material used and to beverage vendors to make sure that their product is delivered safely to its customers.

    Secondly, it’s a matter of price, or is it?  I would challenge any manufacturer that they cannot afford NOT to have a CT machine or at least have access to one. The three words I would like you to remember are compromise, liability and reputation.

    Throughout the history of industrial metrology, quality and R&D engineers have had to compromise and make decisions on what they should measure based on the technology and time they have had available to them. They have asked, “What are the dimensions that I believe to be critical?”, “What do I think is wrong with my component or complex assembly?” and “Why doesn’t it work?”

     

    View showing how different materials in an assembly (a lipstick in this case) can be isolated, enabling a full analysis of how the mechanisms interact. 

    With CT you can capture the complete part (the shape and dimensions, the density, the material flow, any porosity, cracks or inclusions). This data is stored in “Voxels” (like 4D pixels), at Wenzel America we call this the “Part DNA” – It’s everything that the part is, it’s everything that defines the part or finished assembly.

    If engineers have the Part DNA, they can do everything they need to do, now or later – inspection, NDT, archiving, reverse engineering and investigation.

    If you have taken the time, effort and money to develop a significant product, such as a new smart phone, the cost to keep its “DNA” on file is insignificant compared to the potential benefits.

    The engineer also has the option to store this Product’s DNA for later measurement or for full archiving of everything to do with the part for future ‘protection’ of the supplier.

    This leads us to my second word – liability.

    Often the parts measured by CT machines have quite low value in themselves, but failure of such parts in the field can lead to disastrous effects, particularly where human safety is an issue. This could be parts for aircraft or automobiles, but also medical devices and electrical equipment or connectors. Also, simpler consumer products that are sold in the millions can fail with equally expensive effects on recall and company reputation. Archiving the Product DNA of parts allows them to be re-analyzed in the event of a field failure to provide rapid correction or disprove a potential lawsuit.

    Expert investigators can also use CT data to prevent counterfeiting of copyrighted or patented products again reducing liability and retaining profits. In fact the “Part DNA” generated by the CT system could be a part of the patent.

    Potential users of CT data can ask themselves the question “What is the cost of not using CT data to make sure I have no future liability?” All of a sudden the price of a CT machine or the use of a CT bureau service could become very attractive.

    Our final word to consider is reputation.

    What is the cost of a recall to a car company because something doesn’t work? What is the cost of loss of market share to a medical device manufacturer or antiperspirant manufacturer if the device does not function properly? Besides potential lawsuits, the loss in reputation and market share could be a financial disaster.

    Industrial Computed Tomography is not too new, but the justification and the reason for its existence (it’s DNA) has not been explained well to its potential customer base so far. Rather than seeing CT as expensive, the real cost of not using the technology must really be understood. If this is really thought through, the pay back for such an ‘expensive’ machine can be made in days, not years.

    Doctors and hospital administrators use some 20,000 medical CT scanners in the United States so that they don’t compromise with patient care and diagnosis, but also use them in order to reduce their potential liability and to ensure that they do not damage their reputation.

    Contact the team at Precision to learn how Computed Tomography can benefit your company and to schedule a demonstration.

  • Hard Gage Calibration Principles and Methodologies

    Calibration is a comparison of a known to an unknown. A standard of known size is used to check a Unit Under Test. Four critical components of calibration are the operator, the gage being used to check, the Unit Under Test & environmental factors, such as temperature and humidity.

    The operator is to be familiar with the calibration procedure, the gage being used to check should be of traceable size from its most recent calibration, the Unit Under Test should be cleaned of any foreign object debris and normalized to the environment where the test is to be taken, and the temperature/humidity of the area should be at/or correctable to 20 degree Celsius with no more than 45% humidity.

    Methods of Calibration

    Pin/Plug gage sizes represent their diameter. Diameter the distance between two points whose connecting line passes through the center. This allows for an infinite number of diameters on every pin/plug gage. By using equipment that measures the distance between these two points, the size of the pin/plug gage is determined. Calipers, micrometers, Universal Linearity Machines & bench micrometers are all examples of two-point measurement equipment described as such:

    Caliper

    A standard caliper is a hand tool that consists of a sliding jaw measuring against a fixed jaw. Parallelism of these jaws ensures the consistency of measurement, no matter where on the jaws the measurement is taken. The cylindrical gage is placed between the jaws, which are then closed onto the pin/plug gage, giving a measurement of diameter.

    Micrometer

    An outside diameter micrometer is a hand tool that works by bringing a movement anvil towards a stationary anvil. Again, parallelism of the anvils is maintained to ensure the entire surface of the anvils may be used. Flatness is another measurement monitored to reduce error is measurement. A concave or convex anvil will not read the same throughout the entire surface of the anvil.

    Universal Linearity Machine

    A Universal Linearity Machine, or ULM, consists of adjustable ends; one of which has a moveable arm and the other a stationary arm of adjustable length. Anvils are attached to these ends and length standards of known size are used to set the ULM. The pin/plug gage is then placed between the arms and a measurement is taken. Large gages are fixed on a table that has vertical movement. A diameter can then be taken at different heights once the gage is secured. Sine error is minimized by tilting the stationary table to make the anvil point of contact as perpendicular to the gage under test as possible.

    Bench Micrometer

    A bench micrometer is a lot like a micrometer hand tool, except it’s much larger and has an adjustable stationary anvil. These micrometers have linearity, flatness and parallelism that are checked with traceable standards. A cylindrical gage is then measured between the anvils. Force of the movement anvil is adjustable. Cylindrical gages have recommended forces to which they are to be checked.

  • Congress Makes Some Equipment Buying Tax Benefits Permanent

    Companies looking to continue keeping up with technology improvements by updating their equipment have new help in that approach.

    Congress has made a bipartisan move on tax policy that makes some tech, equipment buying tax benefits available for the long term. There is a range of benefits for companies, including making the enhanced version of the Section 179 deduction permanent.

    The 2014 Section 179 tax extender was passed in late December 2014 giving companies little time to act on the provision (you have to take possession of the machine to claim the deduction). The same happened in 2015, but with a twist. Section 179 has been past retroactive for 2015 with the $500,000 deduction limit (without the measure the limit was $25,000), but this time the rule has been made permanent.

    Congress passed the measure in mid-December, and it was signed into law by President Obama - along with a comprehensive Omnibus spending measure. This is significant for companies. The tax bill is a major compromise that offered a range of benefits for different groups. It’s been attacked by some as welfare for businesses, but each side of the Congressional aisle got many provisions they wanted.

    The key is getting some certainty back into the tax code, which is important if you’re running a business for the long haul.

    The bill also includes a five-year extension of bonus depreciation for property acquired and put in service during 2015 through 2019, with an added year of certain property with a longer production period. The bonus is 50% for property put in service in 2015, 2016 and 2017. It slides to 40% in 2018 and 30% in 2019.

    Talk with your tax adviser before year end to make sure you maximize the tax benefit of any purchases you made in 2015; and review your equipment buying plan for 2016 with an eye toward this now-permanent Section 179 provision.

     

  • What is Metrology Close To?

    Measurement is that part of science that is nearest to religion, since in this area the scrupulous testing of right and wrong is the issue: one could say that measurement is the nemesis of any incorrect scientific theory and procedure. For this reason throughout history religious movements have appropriated to themselves the symbols of measurement, as expression of the absolute they are searching. But the history of metrology proves that one cannot study measures except in an atmosphere free from any outside consideration; it appears here most clearly that science only can be a law to science. - From a History of Measures by Livio C. Stecchini

  • Transform your CMM Performance with Renishaw's 5-Axis Touch-Trigger System

     

    Unlike conventional touch-trigger measurement methods which rely on speeding up the motion of the CMM's 3 axis to measure quickly, PH20 utilizes the head motion technology developed for the multi-award winning REVO system to minimize the dynamic errors of the CMM at higher measurement speeds.

    PH20's unique ‘head touches' allow measurement points to be taken by moving only the head, rather than the CMM structure. Points can be taken faster and with improved accuracy and repeatability.

    Furthermore, 5-axis motion eliminates time spent indexing the head. Together these speed increases typically result in a 3-fold improvement in throughput over conventional systems.

    To learn more about the PH20 and how it could improve the throughput of your processes, contact the team at Precison today.
