Mitutoyo measurement service aids FeTu’s developments

Now in its 40th year of operation, Mitutoyo UK supports its customer base, not only with the supply of precision products, but also with the provision of a wide range of complementary services. In addition to product training, IT support, calibration and repair resources, Mitutoyo UK also offers a subcontract measuring service to small and large organisations alike.

An example is FeTu – an innovation driven enterprise that has developed a ‘revolutionary’ green energy device that targets carbon reductions across a broad range of systems and industries. FeTu’s disruptive technology is a versatile ‘continuous positive displacement’ machine that is suitable for a wide range of applications.

The Elland, West Yorkshire-based company’s lightweight and scalable technology uses just two moving parts to operate four anti-phased compression chambers and offers low-loss conversion from potential to kinetic energy.

As a relatively young dynamic business that is involved in the design, development and testing of its ‘roticulating’ technology, FeTu currently subcontracts all of its manufacturing activities. Company founder and CEO, Jon Fenton recently searched for a source of independent, high-precision inspection. He found the solution in Mitutoyo’s Measurement Services.

Prior to the assembly and testing of each new iteration of FeTu’s designs, having previously written the required CMM software programs, Mitutoyo’s staff use one of the company’s Crysta-Apex S series CNC CMMs to perform a range of in-depth, high-precision inspection routines on FeTu’s components. Following each routine comprehensive inspection reports are provided.

FeTu’s association with Mitutoyo’s Measurement Services department has resulted in a range of tangible benefits as Mr Fenton explains: “As tradition has it, in visualising an engine, pump, compressor, turbine or expander we imagine five discreet machines which all appear and function in very different ways. The beauty of our technology is that it is able to accomplish each of these functions in a much more efficient way than they are performed by current, traditional technology.

“The two dynamic parts of the FeTu system do not make contact but run so close to each other as to make an effective seal. The sealing effect is aided by the leakage path lengths being so long that they stagnate flow. To ensure that an efficient seal is achieved, the system’s two moving parts have extremely tight dimensional tolerances. Therefore, a major aspect of our design, development and testing activities has been achieving the required levels of accuracy that allows efficient and reliable sealing to be accomplished.

“The CMM inspection work undertaken by Mitutoyo and the comprehensive inspection reports supplied to us are invaluable. In addition, the speed and in-depth nature of the feedback we have received from Mitutoyo has helped us to truncate our developments times.”

Mitutoyo’s Measurement Services Department supports companies across the UK that are involved in a wide variety of industrial sectors. Typically, businesses are helped on occasions when their QA inspection demand surpasses their in-house capacity. Also, when the need for component measurements exceeds the ability or physical capacity of companies’ metrology equipment.

Mitutoyo Measurement Services department manager, Andrew Fifield concludes: “Our team uses a range of state-of-the-art metrology equipment that enables the most demanding of components to be measured, profiled, analysed, scanned, programmed or compared to CAD. In addition, we are able to accommodate all QC, QA production or SPC requirements.

“Having liaised with Jon Fenton at FeTu, we concluded that the use of a Crysta-Apex S series CMM was the ideal means of achieving the required levels of precision and the speed of feedback needed. Also, via our MCosmos software we were able to create customised and detailed inspection reports that met FeTu’s demanding needs.”
