LESTER FRANKS EXPANDS METROLOGY AND 3D LASER SCANNING SERVICES

LESTER FRANKS EXPANDS METROLOGY AND 3D LASER SCANNING SERVICES

If you see Lester Franks' engineers smiling wider than usual, it because there’s nothing more exciting than a new piece of cutting edge precision equipment. And we couldn’t be happier, having just added the latest in precision 3D laser scanning technology to our portfolio of survey and metrology equipment.

Lester Franks’ new Romer Absolute 7525SI portable co-ordinate measuring machine (CMM) extends our existing metrology grade 3D laser scanning capabilities and continues our legacy of literally being able to measure “from-microns-to-mine-sites”. With a measurement accuracy of better than 30 microns (0.03mm) the Romer Absolute Arm makes short work of even the most challenging measurement tasks.

 The arm-based CMM offers unparalleled flexibility as it provides both tactile touch probing and 3D laser scanning. It’s the natural choice for Lester Franks where unique projects are our bread and butter.

A 3D laser scanning speed of up to 460,000 points per second coupled with the scanner’s exceptional performance on challenging surfaces (including chrome and dark surfaces) mean there is almost no need to prepare a surface for scanning.

The Romer Absolute Arm also integrates seamlessly with Lester Franks’ existing high-end dimensional inspection and reverse engineering software such as Polyworks and Geomagic software suites.

The Romer Absolute Arm is typically used for:

DIMENSIONAL INSPECTION AND ANALYSIS

As Engineers with considerable experience in manufacturing processes and manufacturing process improvement, Lester Franks can improve and refine client’s original parts while also reducing costs and re-work.

Dimensional-Inspection

Dimensional Inspection and Analysis typically involves:

  • Scan to CAD comparison
  • Geometric part verification including GD&T based inspection
  • Jig and fixture setup and calibration
  • Precision alignment of machinery
  • Statistical process control
  • Deformation analysis for identification of warping, shrinkage and other manufacturing defects, and
  • Tabular, graphical and interactive dimensional conformance reports tailored to meet clients’ unique requirements.

REVERSE ENGINEERING

Metrology grade systems such as the Romer Absolute Arm enable Lester Franks to capture complex freeform surfaces in just minutes without compromising accuracy and resolution, which are vital in developing reverse engineered 3D CAD models for small and large parts, assemblies and fabrications.

One of Lester Franks’ unique advantages is our ability to combine multiple instruments, including measuring arms, laser trackers and terrestrial 3D laser scanners to extend measuring ranges, while retaining sub-millimetre accuracies over distances of more than 100 metres. This enables capture of even the largest items such as aircraft and large mining equipment where exacting tolerances are often critical.

Our CAD designers excel in developing 3D scan data into 3D CAD models suitable for direct manufacture, whether fabrication, machining, injection molding, casting or 3D printing. We also routinely develop 3D CAD models for engineering analysis such as Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) purposes.

After all, it’s what you do with the data that really counts.

 WE ARE PROBLEM SOLVERS

 We pride ourselves in being able to tackle spatial problems of any shape and size. For more than a decade Lester Franks has offered metrology grade 3D laser scanning consulting services across a wide spectrum of industries including Automotive, Aerospace, Marine, Mining, Defence and Power generation.

 Our clients rely on us to deliver the right answers first time, every time. There is a big difference between thinking you are right and knowing you are right. The new Romer Absolute arm gives us the confidence we are giving our clients the answers they need with the accuracy we expect.

 ONGOING INVESTMENT IN LEADING EDGE TECHNOLOGY

 In welcoming the Romer Absolute Arm to our stable, Lester Franks continues our commitment to investment in the latest metrology and survey technology on the market.

 In 2015 we upgraded to Leica Scanstation P30 and P40 3D laser scanners following on from the addition of a Leica AT402 Laser Tracker for large scale industrial metrology projects in 2014.
