to be out of tolerance, the customer can be informed so a decision can be made as to the feature’s relevance and whether machining should go ahead anyway. The importance of harnessing all these technologies can be gauged by the fact that the raw castings are so expensive that machining adds only 20 percent to the cost of a finished component. For the same reason, scrap is assiduously avoided, accounting for only 0.015 percent of cell throughput. Another feature of Okuma machines that T&R Precision appreciates is the Thermo- Friendly Concept design, involving both the machine structure and the spindle. It allows the aero engine parts to be machined to within ± 25 microns, despite a significant variation of temperature on the shop floor in Foulridge. Space for 30 machine pallets in the Cellro store allows up to 30 hours’ production without operator attendance, so there is no need for a manned night shift and full advantage can be taken of lights-out operation at the weekend.
With an OEE (overall equipment effectiveness) in excess of 80 percent, it adds up to a highly productive facility in its present form, while the flexibility to add a second VMC has the potential to double output and extend unattended running further. The final word went to engineering manager Graham Gilbert who said, “The support provided by NCMT throughout the project was fantastic. It was useful to be able to visit Okuma’s European headquarters in Germany with them to prove out various parts of the process. “The engineer the agent deployed in our factory for several weeks after installation was knowledgeable and very patient with us during the training period. “This was important as, although we operate a couple of dozen multi-axis CNC machining platforms on a daily basis here in Foulridge, the MU5000V was the first machine we had bought from this source so we were on a steep learning curve at the outset.” n www.ncmt.co.uk
