Advanced Techniques Developing Performance Cutters

项目摘要

Milling cutters, such as ball/toroid/flat end-mills, reamers, and boring tools, etc., and drilling cutters are crucial to machining efficiency, part accuracy and surface finish, and tooling costs. Although cutting tools have a long history of industrial application, cutting tools even now are designed by engineers in the conventional way – trial-and-error with experiments. With more and more new metal materials adopted in industry, new cutters should be developed, instead of using conventional cutters. Unfortunately, the conventional way heavily depends on the designers’ experience, and it is quite costly and long. Despite of the technical barriers, new techniques of developing high-performance cutters are urgent needed in industry. Based on the applicant’s expertise on CAD and CNC machining and his previous research on cutter design and manufacturing, he proposes a new and advanced research program including three topics: (1) formulating complex cutter surfaces with the specified parameters and generating wheel paths for multi-axis CNC grinding of these surfaces, (2) end-mill and drill flute design and optimization, and (3) investigation of a mechanistic model of tool wear. Although the current technique of developing cutters is far from desired, this proposed research can significantly advance the technique and benefit the tooling and machining industry.

铣刀，如球头/环形/平头立铣刀、铰刀和镗刀等，以及钻刀对于加工效率、零件精度和表面光洁度以及刀具成本至关重要，尽管切削刀具具有悠久的历史。在工业应用中，即使现在，工程师仍然以传统的方式设计刀具——通过实验进行试错，随着越来越多的新型金属材料被工业采用，应该开发新的刀具，而不是使用传统的刀具。传统方式很大程度上取决于尽管存在技术障碍，但基于申请人在 CAD 和 CNC 加工方面的专业知识以及他之前对刀具设计的研究，开发高性能刀具的新技术是迫切需要的。和制造方面，他提出了一项新的高级研究计划，包括三个主题：(1) 使用指定参数制定复杂的刀具表面并生成用于这些表面的多轴 CNC 磨削的砂轮路径，(2) 立铣刀和钻槽设计和优化，以及(3) 刀具磨损机械模型的研究尽管目前开发刀具的技术远未达到预期，但这项研究可以显着推进该技术并使刀具和机械加工行业受益。
