The difference a year makes

The opportunities have helped increase turnover by 30% in a year. Additionally, the firm has become less reliant on motorsport work, which has fallen from 80% of the workload to 60%. The remainder now includes its own products and those for electronics, telecoms and defence sectors. All this is said to be credited to the investment in the router and the software.

A year down the line and the company is delighted with its purchase, Farren said. “We manufacture aluminium and epoxy patterns and tools in male or female format for our epoxy pre-preg parts/tools. We transfer jobs from part models in Solid Works to the Hyper CAD package. This allows us to generate a CAD model of the tooling or pattern required and add-in features.” He explained that this enables the manufacturing team to review the complete tool pre-production and ensure it was fit for purpose before exporting the file to Hyper Mill for the tool paths to be generated for the machine tool.

Since the Hyper Mill and Hyper CAD introduction, the benefits are reportedly evident. The very first job produced internally was a six-cylinder air-box epoxy male pattern that required a carbon mould tool. The company then fitted an oil mister system and progressed to machining alloy moulds previously manufactured externally with a lead-time of seven days per part; three parts completed the assembly, so the 21 days required were too long to win the contract. By using the software, the company finished all three components in the seven-day timescale, reducing lead times by 40%.

Cutting through the chop

On a project to reverse-engineer in CAD and produce an 18-foot skiff mast extension and spreader assemblies for a sailing boat, the task required three parts, and each needed a two-piece tool for production. If they were to be externally produced, each tool had a minimum lead-time of three days – a total of three female two-piece tools. By conducting the project internally with the software and the 5-axis machine, the entire contract was completed in three days.

Hyper Mill offers specific advantages, Peter Farndell, Reverie's manufacturing engineer, explained: “The Z-level finishing feature has improved productivity when cavity-machining our mould tools whilst simultaneously enhancing our surface finishes.”

According to company founder Farren, “Since acquiring the 5-axis router and the Hyper CAD and Hyper Mill packages, we have improved cycle times, product quality and reduced our overall lead-times. Most impressively, our capabilities have increased beyond recognition and this has enabled us to win new orders and bring in work previously outside our scope. Without the new machining capabilities and the Open Mind software, the company growth and the extensive product range wouldn’t have been possible.”
