摘要

The word 'machinability' refers to the relative ease with which a given material (or group the materials) can be machined using appropriate tooling and cutting parameters. Several criteria are used to evaluate the machinability, the most important arern1. tool life or tool wear ratern2. cutting forces or power consumptionrn3. surface finishrn4. limiting rate of metal removalrn5. chip shape.rnHowever, machinability is affected by the properties (mechanical and physical) of the work material, tool material, machine tool, part, fixture, cutting fluid and cutting parameters. For this reason, an improvement of the technical capability to predict the machinability is very important for the modern manufacturing industries. The purpose of this special issue is to present a collection of examples illustrating the state-of-the-art developments of experimental and numerical techniques and its applications to machinability of materials.
