Definition: A cutting insert is a replaceable polycrystalline or carbide tip that is mechanically clamped onto a tool holder to form the cutting edge. It provides multiple cutting edges and is indexed or replaced when worn, reducing tooling costs and downtime.
Example in context
“The engineer recommended switching to a coated carbide cutting insert to improve tool life and achieve a better surface finish on the hardened steel workpiece.”
“Mühendis, sertleştirilmiş çelik iş parçasında takım ömrünü iyileştirmek ve daha iyi bir yüzey kalitesi elde etmek için kaplamalı karbür kesici uca geçilmesini önerdi.”
Where engineers use it
Cutting inserts are selected based on workpiece material, coating, and geometry. Engineers specify insert grade and chip breaker design for each operation to maximize productivity and tool life.
Synonyms: tip, indexable insert, throwaway tip
Antonyms: tool holder
