For ceramic tool substrates, slot milling performs a good cutting edge engagement. A cutting force Fc of 28.8 N can be detected during the slot milling process of Inconel 718 with ceramic end milling tools (shown in Fig. 5). Because of the used machining parameters presented in chapter 2, a chip cross section A of 0.036 mm² is achieved.

machining. Nickel alloys are classified into different categories according to their relative machining behaviour as shown in Table I. A different set of machining conditions is applicable to each category, and the first step for successful machining is for the programmer/machinist to identify the applicable category for the alloy to be machined.

This video from Coromant shows ceramic milling in action. The ceramic insert grade seen here, CC6060, is typically used for milling Inconel 718 engine casings (the workpiece seen here is Inconel 718) as well as for milling components for oil drilling equipment. In both cases, the value of milling with ceramic rather than carbide is a ...

When Inconel is work-hardened, tooling can wear out as heat and pressure builds. Carefully inspecting tooling is critical for maximizing quality in Inconel machining. Tip #2: Start with a Solutionized Piece of Metal. Cold-drawing metal hardens the work surface. This makes Inconel even harder to work, causing more stress to tooling.

For instance, when machining an imbalanced part made of Inconel 718 with a hardness of 46 to 48 HRC, the low-end cutting speed needed for ceramics to plasticize the material is about 550 to 600 sfm. In contrast, an XYSTIN-1 insert can run at 350 to 400 sfm whereas a carbide tool would reach only 150 to 180 sfm.
