Choosing a gouging method

The plasma cutting process was invented in 1954 at the Tonawanda Laboratory of the Linde Division of Union Carbide A young scientist Robert Gage discovered that by forcing a gas tungsten arc through a small orifice in a process similar to focusing a beam of light through a lens the temperature and intensity of the arc could be increased

Process Insights Understanding the Elements The Coordination of Materials Coatings and Geometry Key To High-Speed Aluminum Machining Technological developments such as the Makino MAG-Series machines have made tooling vendors rethink the core concepts of their tooling designs To get the most out of any state-of-the-art machine technology it is vital to apply the right tooling and

Calibrating Feeds and Speeds When Using Carbide

NOTE If you are testing very hard or brittle materials (like mother-of-pearl or non-ferrous metals) start with an initial feedrate that yields a TOTAL chip load less than 2% If you are testing a thermoplastic or any material that tends to soften and melt select an initial feedrate that yields a TOTAL chip load of at least 4% to prevent swarf melting and bit seizure

How and When to Perform a Copper Sulfate Test —

Selecting a Carbide End Mill for Aluminum Applications

A high helix angle generally around 45 degrees is also desirable The helix helps move chips up and out of the cutting zone and also generates an excellent surface finish The angle also helps soften the impact at entrance of cut resulting in a smoother quieter cut (see Figure 1) For aluminum milling a two- or three-flute end mill works best because this allows for larger flute areas
