Abstract A great deal of research has been done during the last twenty years on the modeling and control of NC machining. Despite the promise of substantial productivity improvements these methods are sparsely used outside their academic birthplaces. We believe that Open-Architecture Controllers (OAC) are the key to unlocking this unfulfilled potential. We describe the implementation of novel methods for feedrate optimization which utilize a commercially available OAC. In this paper an example is given of how substantial improvements in machining processes can be achieved by implementing geometric and mechanistic models of the cutting process on an OAC. These benefits should provide motivation for a more universal adoption of OACs.

To make full and reasonable use of natural light in civil buildings has an important meaning to the construction of green buildings. This paper has designed an intelligent sunshading control system based on Lonworks fieldbus. Based on the analysis on the sunshading control needs of civil buildings, this paper has proposed a system framework based on Lonworks fieldbus, and has designed control nodes of intelligent curtains from the two aspects of hardware nodes and control software. At last, this paper has also designed the host computer monitoring software.

As the common materials of making cutting tool, the cemented carbide has been widelyused in all kinds of mechanical machining. Based on the manufacturing craft of the brazing welded cemented carbide cutting tools, according to the theory of engineering mechanics and fracture mechanics, the main factors are analyzed and studied which influence surface cracks of cutting tool from prefabricated stress σc, brazing stress σq, removable stress σw at heat preservation and extra stress σf several aspects in this paper. Then the author founded the math-mechanics model of forming the surface cracks and deduced the critical condition generated surface cracks in brazing welded cemented carbide cutting tools and puts forward several kinds of technology, crafts and methods restraining or minishing surface cracks of the cemented carbide cutting tools.

Advances have been made in the art of metal cutting, much to the economic benefit of industrialized nations. Not withstanding this, engineers continue to seek stronger and lighter materials. New challenges emerge as we seek to understand and control the deformation of a small volume of material in the immediate vicinity of the cutting edge. In this paper we use a metallurgical approach to explore and understand the nature of high strain deformation in light metals and its influence on the chip forming process. In particular the phenomenology of material flow around the cutting edge is discussed on the basis of previous studies of machining in the SEM. The issue of chip separation is discussed, particularly in relation to its impact on the tribology of the ship / tool / workpiece interface. The objective is to better design cutting tools and their vapour deposited coatings for improved machinability in light metals.

3D Digitization

The paper presents the bases of a methodology for obtaining a 3D solid model by three-dimensional scanning. The three-dimensional scanning has been available for more than 15 years; and yet, some people have heard of it but a few are familiar with the applications of this technology. 3D scanning is also known as 3D digitization, its name coming from the fact that it is a process that employs a contact or non-contact digitizing feeler in order to capture the form of objects and recreate them as 3D graphic representations in a virtual work space through a very dense network of points (xyz). By means of certain specialized programmes, we can obtain not only the tool’s geometric parameters that can be compared with the obligatory parameters, but also a direct evaluation of the geometric deviations from ideal values.

Statistical control charts have been successfully used in industry for monitoring stable processes. However, processes with uncontrollable but acceptable trend are common in practice. One typical example is the wear process of cutting tools. Conventional control charts may not serve the purpose of process monitoring. In this paper, a forecast-based technique using Double Exponential Smoothing is proposed. It eliminates the trend component, and control charts are applied to the residuals. Furthermore, a procedure based on double control lines is suggested and adopted in tool wear process monitoring to integrate statistical and engineering properties for better decision making on tool wear-out. Other than the monitoring of tool wear process, the method can be used for better monitoring of other processes with trend. An actual tool wear data set is used as illustration.
