“We achieved all that within five months, thanks to Alphacam’s built-in machining strategies which helped us to optimise our high-end machines and cutting tools.”
ALPHACAM CNC PROGRAM FULL
Being aerospace, there were AS9102 reports with every component, and it meant that the processes were sealed, so that when they did go into full production there were no more qualification periods to go through. Neil added: “We were tasked with not only manufacturing them from scratch, but producing them as if we were making them in large volumes, so we needed tight cycle times.
ALPHACAM CNC PROGRAM SOFTWARE
He says the software was an essential piece of the equation when it came to producing the Hawk 8000 Cargo Hook components, mainly from aerospace aluminium and billets of hardened AMS 5643 American spec stainless steels, along with a small amount of plastic. The only one it doesn’t drive is the Spark Eroder, which has conversational software.” Neil said: “It drives all our 3- and 5-axis Matsuura Machining Centres, CMZ Y-axis and 2-axis Lathes and Agie Wire Eroder. Leemark director and production manager Neil Stockwell explains that 11 of those machines are programmed with Alphacam. Most components are highly complex, manufactured on 12 CNC machine tools at its factory in Middlesex. Principally supplying precision components to Tier 1 aerospace companies, its parts can be found on aircraft such as the Lockheed Martin F-35 stealth plane, the Saab Gripen E fighter jet and various military, police and civilian helicopters, along with ejector seats and satellites. It was set up by their father over 50 years ago, and they retain the family ethos of quality and customer service. Leemark is run by three brothers, Mark, Kevin and Neil Stockwell. The company had already worked with Leemark Engineering on a number of products, and approached the firm to manufacture the casings, solenoid covers, heavy-duty linkages, levers and pins for the assembly. The Hawk 8000 Cargo Hook has been selected for the next-generation Bell 525 Relentless helicopter, which is currently being developed.ĭrallim Aerospace were contracted to design the hook which needed to be capable of handling an 8,000lb payload. A company specialising in manufacturing complex aerospace components helped develop a family of 45 high-spec parts for a helicopter cargo hook in just five months, using Alphacam CAD/CAM software.
