If you have experience milling titanium, nickel alloys are similar. Sturdy fixtures are important. Getting the most metal removed per flute engagement is key to milling economy, and tool usage economy. My advice, get a block of nickel and run your own tests using your programming style, your tooling, and machinery.
To combat the difficulties in the machining of nickel-based superalloys, such as poor thermal diffusivity and high levels of abrasive wear, trochoidal milling was introduced as an alternative method of milling. This method of milling combines linear motion with uniform circular motion, reducing chip load in exchange for increased machining time.
Experimental method For the synthesis of Ni 0.5Zn 0.5 Fe 2O 4, pure nickel nitrate [Ni (NO 3) 2 6H 2O], zinc nitrate [Zn (NO 3) 2 6H 2O] and iron nitrate [Fe (NO 3) 2 9H 2O], all from Aldrich, were used as received without further purification. The required amounts were weighed and mixed accordingly in a vial to achieve the stoichiometry.
The ECY-S5 end mill with five flutes features a general-purpose substrate and AlTiCrSiN coating (IC608) for shoulder or full slot high-speed milling or trochoidal or peel milling. Its primary application is stainless but it can also be used to machine nickel-based, high-temperature alloys.
