Machinability is a generalized framework that attempts to quantify the response of a workpiece material to mechanical cutting, which has been developed as one of the key factors that drive the final selection of cutting parameters, tools, and coolant applications. Over the years, there are many attempts have been made to develop a standard evaluation method of machinability. However, due to the complexity of the influence factors, i.e., from work material and cutting tool to machine tool, that can affect the materials machinability, currently there is no uniquely defined quantification of machinability. As one of the outcomes from the CIRP’s Collaborative Working Group on “Integrated Machining Performance for Assessment of Cutting Tools (IMPACT)”, this paper conducts an extensive study to learn interacting machinability parameters to evaluate the overall machining performance. Specifically, attention is focused on recent advances made towards the determination of the machinability through tool wear, cutting force and temperature, chip form and breakability, as well as the surface integrity. Furthermore, the advanced methods that have been developed over the years to enable the improvement of machinability have been reviewed.

回顾当前可加工性评估和理解以提高加工性能的最佳实践

机械加工性是一个通用框架，试图量化工件材料对机械切削的响应，它已成为推动切削参数、刀具和冷却液应用最终选择的关键因素之一。多年来，人们为制定可加工性的标准评价方法进行了许多尝试。然而，由于影响材料切削加工性的影响因素（从工件材料、切削刀具到机床）的复杂性，目前尚无唯一定义的切削加工性的量化方法。作为 CIRP 协作工作组“切削刀具评估的综合加工性能 (IMPACT)”的成果之一，本文进行了广泛的研究，以学习相互作用的加工参数来评估整体加工性能。具体而言，人们的注意力集中在通过刀具磨损、切削力和温度、切屑形状和易碎性以及表面完整性来确定切削加工性方面取得的最新进展。此外，还回顾了多年来开发的可提高机械加工性能的先进方法。
