The application of AI technologies using modem computers and controllers is seen as a way forward to produce higher quality components more efficiently with smaller batch sizes and more frequent changeovers. Users continue to demand better accuracy, surface integrity, and shorter cycle times with reduced operator intervention and increased flexibility. This paper reviews research into the use of intelligent control and optimisation techniques in grinding and propose the incorporation of intelligent techniques into computer numerical controls (CNCs). Two main trends are evidenced in the development of AI technologies in grinding: desktop systems to assist tool and parameter selection and self-optimising systems integrated within the machine controller. It is predicted that future developments will favour increasing incorporation of intelligence into CNC. The development of modular systems which are sufficiently robust to plan. supervise and control abrasive processes requires ongoing research and development.

The Process Approach is a method to solving problems in Operations Strategy Management (OMS). This method drives the conception and development of an operationalization process of conceptual frameworks, supported by a set of instruments and coordinated by managerial procedures. Although solidified and broadly used, the Process Approach application is still manual, which can compromise the integrity of applications, generating an inadequate operationalization process. With the objective of to contribute to guarantee the integrity of the application of the concepts used by the Process Approach, it has been developed a Processes Productions Process (PPP) to solve problems in the OMS. This PPP organizes and systematizes the application of Process Approach through the use of the P3Tech technology. The P3Tech technology comprehends a set of method, technique and tools for contextual processes modeling and simulation. The PPP generates a method that can be applied by companies as a competitive weapon. Finally, this work makes recommendation to generate information systems in conformity with the processes generated by PPP.

This paper describes in two parts a new method and device for measuring motion accuracy of NC machine tools. In the first part, the measurement principle and the characteristics of the prototype device have been presented and discussed. In the second part, an efficient and practical approach to identifying the errors of the proposed device after assembly is developed and evaluated. The approach ensures realising the aim of the investigation, i.e. to measure the most items of the motion accuracy, especially, to measure and assess the trajectory accuracy of a general planar motion of NC machine tools. The result of the identification experiment by using the prototype device on a machining centre for the prototype device is presented and it well verifies the validity and practicality of the approach. Some measurement results for the general planar motions of the machining centre are also shown, which sufficiently demonstrate the desirable capability of the proposed method and device.
