Becoming CNC approved machinists

I am very interested in joining a company of CNC approved machinists, but due to lack of experience in the field, would like to hear more suggestions from others on how to become one? I have experience in CNC Desktop since 2002, have done a lot of Research on CNC machining, and would go one step further to operate large CNC machining centres like Bridgeport VMC, YCM, Leadwell, Victor, Haas, etc … I have

joined forums, I know how to use manual CNC milling, facing, CNC drilling equipment. I can use Autocad 2D: Mastercam, VisualMill, Delcam, PowerMILL, Visi. This is typical of many youngsters who currently have their aspirations frustrated. Some of the best opportunities lie with the Aerospace sector.

Aerospace manufacturing and CNC machining.

Machining solutions for the latest generation aerospace materials, for example, new metals like titanium-based alloys ATI 5553 for Boeing, are sought on an ongoing basis. Milling cutters to machine the landing gear components for Boeing.

Tubular components have always been tricky due to vibration. Cutting tools that are more stable and much smoother under cutting pressure have been developed.

5-axis machining of the outer part of circular aero engine components, complex aluminium components such as aero engine housings... these are performance critical parts. The UK is the second largest aerospace parts manufacturer in the

world, behind the USA, but supplying the sector requires significant investment plus the right approvals.

Aluminium, stainless steel, titanium and super alloy parts.

Parts are made from aluminium, stainless steel, titanium and super alloys, and are often required in smaller batch sizes. Exacting surface finish standards and the time savings brought by 5-axis machine tools are the objective. Components are worth thousands. New aircraft make more extensive use both of composite and of titanium materials. Compared to aluminum, titanium is more compatible with composites in aircraft assemblies. The Boeing 787 Dreamliner is 15 percent titanium by weight.

Obtaining enough titanium to meet the needs of the latest generation of aircraft is a challenge. Titanium prices have risen in response to the demand, The aircraft-industry

supply chain will have to realise more capacity and will be asked to machine more titanium than ever before, and also machine it faster.

When machining aerospace titanium, the slow cutting speed means that roughing and finishing are needed in order to remove the volume of material productively. As a result, machining titanium parts effectively involves a series of  discrete operations, with different proven techniques at each step.

OASIS registered audited CNC machining

The aircraft-industry supply chain expertise does exist traditionally in the UK where there are a number of successful organisations and quality control initiatives that guarantee audited CNC machining accredited to AS 9100.

Maypole Precision products also enjoy the seal of approval of major manufacturers in this sector, being GE approved and Messier Dowty approved CNC machinists.
