ProvenCut recipe 586 struck a wonderful balance, machining a piece free of chatter and yielding an extraordinary finish using a YG-1 V7 PlusA six-flute endmill held in a Lyndex-Nikken SK16 collet holder. The 2D contour finishing operation was programmed with Autodesk Fusion 360 and run at 210 m/min. (690 sfm) at 0.015 mm feed per tooth (0.0006" feed per tooth) with a 0.203 mm (0.008") radial DOC and 63.5 mm axial DOC.

Condition of vibration involving the machine, workpiece and cutting tool. Once this condition arises, it is often self-sustaining until the problem is corrected. Chatter can be identified when lines or grooves appear at regular intervals in the workpiece. These lines or grooves are caused by the teeth of the cutter as they vibrate in and out of the workpiece and their spacing depends on the frequency of vibration.
Flexible-sided device that secures a tool or workpiece. Similar in function to a chuck, but can accommodate only a narrow size range. Typically provides greater gripping force and precision than a chuck. See chuck.
Milling cutter held by its shank that cuts on its periphery and, if so configured, on its free end. Takes a variety of shapes (single- and double-end, roughing, ballnose and cup-end) and sizes (stub, medium, long and extra-long). Also comes with differing numbers of flutes.
Rate of change of position of the tool as a whole, relative to the workpiece while cutting.
