WebFeb 5, 2024 · Chip thickness is exactly what it sounds like: the thickness of the chip the flute, or insert edge, creates. Chip thickness principles depend on the type of tool being used (90/45/10-degree cutting angle, for example) and whether the operators is peripheral or face milling. WebTool life is limited by the heaviest cuts and thickest chips. In order to evaluate chip thickness, calculate the maximum chip thickness hex to determine axial feed rate.
