摘要

刀具作为机床的“牙齿”,在金属切削中非常重要,目前专用化是刀具发展的一个主要趋势,挑战刀具设计的灵活性和准确性。为了实现这一目标,提出了刀具“形-性-用”一体化设计方法,它以加工需求为驱动,利用切削过程中涉及的理论(几何约束、切削力作用、切削层作用机理、刀具强度理论、高温材料学属性以及化学反应关系等),并通过刀具设计特征,将刀具的形状、性能和使用结合起来,进而实现针对加工需求的专用刀具设计,以及相应的加工条件和切削参数等的确定。然后建立了刀具“形-性-用”一体化设计方法系统框架,并开发了其软件平台。最后采用示例分析,展示本方法的刀具参数优化过程和刀具建模过程,进而证明本方法的可行性。刀具“形-性-用”一体化设计方法为刀具专用化发展提供一种新方法和新思路。

Abstract

Cutting tool is regarded as the tooth of machine tool, and they play a key role in metal cutting. Nowadays, the customization is a develop direction of cutting tool to improve the machining capability of cutting tool. In this case, the flexibility and accuracy of cutting tool design is the main challenges. Towards the issues, a feature based cutting tool “shape-performance-application” integrating design (CTSPAID) approach is presented, which is driven by the machining requirements. It utilizes the basic theories of cutting process, e.g. geometry constraint, cutting force distribution, cutting layer mechanism, cutting tool strength, high temperature material science, high temperature tribology, chemistry relationship. Integrating all of the related theories into cutting tool design feature (TDF), the method can realize the unification of shape, capability and application of cutting tools. The suitable cutting tool can be achieved, as well as the cutting condition, cutting parameters. Also, the architecture of the cutting tool design system is proposed, and also the software platform of this system. The case study is used to show the details of the process of the approach, and demonstrate the feasibility of the method. The CTSPAID method provides a new idea for the customization of cutting tool.

Key words： cutting tool design; tool shape; tool performance; tool application; tool design feature
