Abstract

The next-generation STEP-NC technology requires automatic generation of machining strategies within manufacturing systems to implement flexible manufacturing in the future. Currently, the machining feature modeling based on STEP-NC is in its infancy, facing challenges such as cumbersome modeling processes, ineffective utilization of the STEP-NC standard, and low development efficiency. A low-code modular solution based on the STEP-NC data kernel for machining feature-oriented modeling is important to achieve more intelligent flexible manufacturing. This paper presents a low-code modular modeling method for machining features, based on the STEP-NC data structure and incorporating geometric, process, and machining information, aimed at part milling. A low-code modular CAD modeling platform based on STEP-NC was built using Rhino Grasshopper. Additionally, a toolpath generation algorithm was designed for milling feature models to enable the automatic generation of milling strategies. Finally, the feasibility of a low-code modular CAD system based on machining features for STEP-NC compliant manufacturing in engineering applications is validated through a case study involving part design, milling, and optimization.

面向STEP-NC加工特点的低代码模块化CAD系统

下一代STEP-NC技术要求在制造系统内自动生成加工策略，以实现未来的柔性制造。目前，基于STEP-NC的加工特征建模处于起步阶段，面临建模过程繁琐、STEP-NC标准利用效率低下、开发效率低等挑战。基于STEP-NC数据核的面向加工特征建模的低码模块化解决方案是实现更智能的柔性制造的重要途径。基于STEP-NC数据结构，结合几何信息、工艺信息和加工信息，提出了一种针对零件铣削加工特征的低编码模块化建模方法。利用Rhino Grasshopper构建了基于STEP-NC的低码模块化CAD建模平台。此外，针对铣削特征模型设计了刀具轨迹生成算法，实现了铣削策略的自动生成。最后，通过一个涉及零件设计、铣削和优化的案例研究，验证了基于加工特征的低代码模块化CAD系统在STEP-NC兼容制造工程应用中的可行性。
