a greener future for aerospace
As one of the largest contributors to global CO2 emissions, there is an urgent pressure on the aerospace industry to provide
greener aircraft that are lighter and can travel for longer distances. However, achieving this requires working with tough- to-machine aluminium and heat-resistant super alloys (HRSAs). Here, Sébastien Jaeger, industry solution manager – Aerospace for Sandvik Coromant, explains how aerospace OEMs can adopt advanced tooling solutions to sustainably machine these tough components.
stages including looking at the machine requirements and time studies to examine the cost-per- component. Also, analysing production methods at the run-off, related both to Methods-Time Measurement (MTM) and end- user processes. The components solution also includes computer-aided manufacturing (CAM) programming and project management of local or cross-border projects. For one Sandvik Coromant customer that
was experiencing chip breaking problems in its production, the components solution allowed us to spot the cause and devise a solution. For the customer, Sandvik Coromant’s specialists developed a new strategy with dynamic drive curves that allowed us to control the chip breaking in every moment. It called this new approach “scoop turning” and now has a patent over it. With scoop turning, the customer achieved an 80 per cent cycle time reduction with great chip control and doubled tool life. Furthermore, the customer was able to
reduce its use of four machine down to one, reducing the need for multi-tasking, with more secure machining processes and green light production. Reduced machine usage and the ability to complete production runs with fewer tool changeovers, thanks to tougher machining grades like S205, will be key to more sustainable aircraft production. Software will also play a vital role, such as

they have even commenced production.
Close the loop
Aside from new approaches to tools and manufacturing, aerospace OEMs can also turn to manufacturing. According to a report by the Air Transport Action Group (ATAG), Kaiser, which is the company that supplies aluminium to Boeing, now employs a closed-loop recycling system - one of the largest programs of its kind in the industry. Kaiser estimates that around ten million kilograms of offcut and scrap metal will be reused by the industry, each year, through the scheme. Sandvik Coromant has initiated its own
circular system for recycling carbide tools whereby it buys back customers’ worn-out carbide tools and re-uses them to make brand new ones. As a result, most of the raw materials used in Sandvik Coromant’s cemented carbides tools come from scrap. The company practices sustainable business in an environment of limited resources and minimises excessive waste. By doing this, it has found making tools
from recycled material requires 70 per cent less energy, while 40 per cent less carbon dioxide is emitted. There is mounting pressure on the
aerospace industry to manufacture greener aircraft that are lighter and travel for longer distances. However, with the right processes and tools in place - not to mention a more holistic approach to manufacturing - aerospace OEMs can do their bit to help establish a greener future for aerospace.
