针对传统刀片和刀杆设计验证存在周期长、成本高、准确性不足等问题，本研究基于NX运动分析技术开展刀片和刀杆设计合理性验证。以内螺纹刀片设计为例，通过NX构建刀片和刀杆三维模型，利用NX运动分析模块，模拟刀具切削过程，验证刀具切削轨迹合理性，并检测是否存在刀片切削干涉或刀杆本体干涉。研究表明，相较于传统实切验证方法，NX运动分析技术显著提升验证准确性与效率，大幅缩短设计周期。实际应用中，经仿真优化的刀具废品率显著降低，同时设计效率得到提升。该成果为刀具研发提供了高效、可靠的数字化验证方案，对推动刀具设计的精准化与智能化发展具有重要意义。

Addressing the issues of long cycles, high costs, and insufficient accuracy in the traditional design verification of inserts and tool holders, this study conducts a rationality verification of insert and tool holder designs based on NX motion analysis technology. Taking the design of internal thread inserts as an example, three-dimensional models of the insert and tool holder are constructed using NX. The NX motion analysis module is then utilized to simulate the cutting process, verifying the rationality of the tool cutting path and checking for potential interferences involving the insert cutting edge or the tool holder body. The research indicates that, compared to traditional physical cutting verification methods, NX motion analysis technology significantly enhances verification accuracy and efficiency, substantially shortening the design cycle. In practical applications, tools optimized through simulation have demonstrated a reduced scrap rate, thereby improving design efficiency. This achievement provides an efficient and reliable digital verification solution for tool development and holds significant importance for promoting the precision and intelligent advancement of tool design.
