五轴加工在自由曲面加工中应用较为广泛。然而，在自由曲面的五轴加工中，计算机数控（CNC）与计算机辅助设计/计算机辅助制造（CAM）之间的信息交换不完全，导致许多限制需要纠正。本文提出了一种基于STEP-NC标准的数控系统新结构，将刀具轨迹规划、刀具偏移和运动学逆解从CAM传递到CNC。为了保证良好的开放性，在开发过程中采用了开放的平台和标准的接口。研究了模块协作技术和数据流设计。实现了用于非均匀有理b样条曲面加工的五轴实时插补器。在此基础上，以软件实现的方式开发了由解释器、任务协调器、轴组、软plc等组成的五轴数控系统。该软件数控系统已在倾斜旋转型五轴机床上得到应用，并成功进行了铣削实验。
Five-axis machining is more widely used in manufacturing of freeform surfaces. However, in five-axis machining of freeform surfaces, incomplete information exchange between computer numerical control (CNC) and computer-aided design/computer-aided manufacturing (CAM) results in many limitations need to be rectified. In the paper, a new structure of CNC based on STEP-NC standard is proposed, where tool path planning, tool offset, and inverse kinematics are transferred from CAM to CNC. In order to guarantee good openness, open platform and standard interface are applied in the development. Technology of module collaboration and design of data flow are studied. A five-axis real-time interpolator for non-uniform rational B-spline surfaces machining is realized. Based on these technologies, a five-axis CNC is developed in the manner of software realization, which consists of interpreter, task coordinator, axis group, softPLC, etc. The software CNC system has been applied on a tilt-rotary type five-axis machine tool, where the milling experiment has been performed successfully.
