The aim of this paper is to provide an introduction and overview of recent advances in the key technologies and the supporting computerized systems, and to indicate the trend of research and development in the area of computational numerical control machining. Three main themes of recent research in CNC machining are simulation, optimization and automation, which form the key aspects of *Corresponding author, Email: welcome.li@nuaa.edu.cn 2 intelligent manufacturing in the digital and knowledge based manufacturing era. As the information and knowledge carrier, feature is the efficacious way to achieve intelligent manufacturing. From the regular shaped feature to freeform surface feature, the feature technology has been used in manufacturing of complex parts, such as aircraft structural parts. The authors' latest research in intelligent machining is presented through a new concept of multi-perspective dynamic feature (MpDF), for future discussion and communication with readers of this special issue. The MpDF concept has been implemented and tested in real examples from the aerospace industry, and has the potential to make promising impact on the future research in the new paradigm of intelligent machining. The authors of this paper are the guest editors of this special issue on computational numerical control machining. The guest editors have extensive and complementary experiences in both academia and industry, gained in China, USA and UK.

Manufacturing companies dealing with high value, high accuracy and complex parts are facing increasing demand for higher quality and efficiency at lower costs and reduced lead times from their global customers. In real-life production such as the Numerical Control (NC) machining processes, there are continuous changes in machine tool performance, cutting tool conditions, workpiece deformation, cutting parameters, in addition to the changes in the geometry and properties of the parts being machined. Some changes are caused by 'predictable' factors such as cutting forces and machine tool deterioration over time, whilst others are caused by 'unpredictable' factors such as sudden breakdowns, uneven material property, vibration and machining chatter, or even human errors. These dynamic factors impose significant difficulties to ensuring machining accuracy effectively especially the controlling of unrecoverable over-cut errors normally causing part failures. This project aims to establish a set of integrated information models to address the dynamics of machining conditions based on the Dynamic Feature concept proposed by the authors, which are used as the basis for integrating machining, monitoring, and on-line inspection operations for optimized machining process control of high value complex parts. A prototype framework based on an open platform has been developed to enable the application of the proposed method. Industrial examples used to validate the prototype will be presented in this paper.

“…Computer aid verification of geometric accuracy is one of domains which applies RE extensively. During the last decade, there were particular interests focusing on freeform metrology especially in aviation industry [1][2][3]5,[8][9][10][11][12]. RE serves as a mean to quantifying complex shapes through an holistic evaluation with nonconformity indices, such as geometric attributes and profile tolerance [2].…”

Reverse engineering is of great interests for computer aided verification of freeform shapes. Accurate model is crucial to assure the validity of geometry assessment. Freeform reconstruction is especially challenging when the parts are thin and/or self-occlusion. An integrated measuring system was proposed by incorporating laser scanner into hardware mechanism on reconstructing model of complex shape. Mathematical model mapping the transformation relationship between system components and cylinder-based algorithm for mechanism calibration was presented. The proposed system was validated on blade measurement. Experimental results showed that the proposed system and calibration method were able to provide a reliable measurement on freeform shape.
