The aerospace industry produces a huge quantity of parts using Numerical Controlled (NC) Machine-tools. The NC programs developed to cut the parts along specific trajectories using Computer Aided Manufacturing software (CAM) generally require long simulations, manual fine-tuning as well as an iterative tool prove mechanism before being able to cut the part as per its specifications. Although this process leads to a good NC program that will produce proper parts, this latter has not necessarily been designed to minimize tool positioning travel times or cutting parameters to ensure constant chip load, as for example. ICAM Corporation, one of the leader in the industry of post-processing and NC simulation software solution, proposes a solution to optimize tool paths produced from CAM simultaneously to the post-processing of G-code and ensuring a collision-free resulting NC program. The proposed research project is to contribute to this development and validate the NC path optimizer through extensive machining experiments. At the end of the project, the new functionalities of the software will propose efficient optimization for cutting trajectories and machining conditions enabling significant processing and production time saving as well as improved quality of parts. High cost savings are expected for typical manufacturing sectors as the aerospace, automotive and mould/dies industries.

航空航天工业使用数控（NC）机床生产大量零件。的 使用计算机辅助制造，开发NC程序以沿沿着特定轨迹切割零件 软件（CAM）通常需要长时间模拟、手动微调以及迭代工具验证 在能够按照其规格切割零件之前，必须先对机械进行切割。虽然这个过程导致一个很好的数控 程序，将产生适当的部分，这后者不一定是为了尽量减少工具 定位行程时间或切削参数，以确保恒定的切屑负载，例如。ICAM公司， 后处理和数控仿真软件解决方案行业的领导者之一，提出了解决方案， 优化从CAM生成的刀具路径，同时进行G代码的后处理，并确保 无碰撞生成的NC程序。拟议的研究项目是为了促进这一发展， 通过大量的加工实验验证了数控路径优化器的有效性。在项目结束时，新 该软件的功能将提出有效的优化切割轨迹和加工 这些条件能够显著节省加工和生产时间，并提高零件质量。 对于航空航天、汽车和模具等典型的制造行业，预计将节省大量成本 行业
