Information of cutting tools is very important for the effectiveness of cutting process. Previously, traditional search method by referring to the catalogues for the right cutting tool has been a burden to the user. As a result, the probabilities of choosing the wrong cutting tools were high. In this work, a new cutting tools management system for milling process has been developed for training students before they actually perform the milling process. With the specific parameters such as cutter, part number, dimension and material types and its properties, the user can easily get detail information of the cutting tools such as cutter dimension, insert types and its properties. User can also visualize the chosen cutter and inserts, interactively. This web application will help the user to find the best cutting tools. It can also help to educate students or any users in understanding the process of choosing the best cutting tools and the parameters needed for the cutting process. Visualization of the milling machine is also provided for the users before the cutting process is performed.

Computer Aided Design of Cutting Tools
With today's growing advancement, computer proves to be very powerful tool and extensively used for both engineering design and drafting purposes. One of the fundamental activities in which engineers involve is cutting tool design. The tool designers job has been simplified in resent years because of the advancement of the CAD technology. An attempt has been made to develop an interactive software in 'C' for designing and drafting of cutting tools, computation of machining parameters, force analysis and selection of materials for various cutting tools widely used in the industries with a great deal of accuracy.
Expert system for the definition of the cutting parameters and machining strategies
The definition of the cutting parameters (Vc, fz, ae, ap), and the definition of the machining strategies or the strategies to engage the tool in the material and to start the cutting process, are usually requested by the CAM systems as input information. These data are usually strongly influenced by the consolidated experience of the operators, by the specific previous similar machining cases and by several other factors depending on the machining practices. In a project, financed by the Swiss national organization for the industrial research, the authors have developed an expert system (ES) in order to get this information through software processes. The paper shows the structure of this expert system. The ES has been realized through the definition of ontology of components and elements of the machining. The ES includes a very large data base of cutting parameters, and is based on the establishment of rules for the competition between the machining strategies. The ES includes learning methods which are able to identify similar operations. The learning methods are based on the measure of the distance between the actual machining conditions and those already experimented. Therefore the system is able to learn from similar cases. The system has been designed especially for an application in the field of the watch industry which requests a very large spectrum of machining operations and includes also the cases of the HSC. The new expert system is today implemented in a CAM, SylvieXpert, commercially distributed by the company Jurasoft.
A web-based virtual CNC turn-milling system
This paper presents a different web-based virtual turn-milling system, which aims to address the common problems of existed systems. The system has not only economical value, such as shortening product cycle from design to market, but also scientific interest, like proposing a new trajectory planning method. In other words, it helps sellers and buyers better understand products and enables planners and machinists to make decision or verify CNC codes much more accurate and faster. This system is made up of three levels, which is client browser, server, and database, and every level is divided into several specified functions. Among all the functions, turn-milling simulation function is the most crucial part. To enhance the system's features, many sub-function modules are also adopted in simulation functions. Through these modules, the system implements material removal function, tool trajectory planning function, numerical control (NC) code inputting and compiling function, and so on. To realize these functions, the whole machining system is developed by using the network superiority of Java language and Virtual Reality Modeling Language (VRML) technology interaction, which will also lead to smaller data volume. Owing to the transportability of Java language and VRML technology as well as the good under-standability of the system, this web-based virtual turn-milling system is also suitable to the dynamic demonstration and machining simulation of other NC machine tools. Some future research directions are given to perfect the system in the end.
An expert mill cutter selection system
2005 IEEE Conference on Emerging Technologies and Factory Automation, 2005
This paper discusses the selection of tools in milling operations. To carry out this research, it has been developed an expert system hinged on numerical methods. The knowledge base is given by limitations in process variables, which let us to define the allowable cutting parameter space. The mentioned process variables are, instabilities due to tool-work-piece interaction, knowing as chatter vibration, and the power available in the spindle motor. Then, a tool cost model is contrived. It is used to choose the suitable cutting tool, among a known set of candidate available cutters, and to obtain the appropriate cutting parameters, which are the expert system outputs. An example is presented to illustrate the method.

In machining industries, the selection of sets of cutting parameters; cutting speed (v), feed (f), and depth of cut (d) do not put much concern on optimization. In practice, they are even set intuitively or by looking at manual reference table. The study commences with constructing a software based optimization tool. The application software optimizes cutting parameters based on production time and cost for turning operations. The development of the software application captures the idea of product development process with the prototype itself assigned as the product being developed. Product specifications and product feature are derived to meet the requirements. Database of cutting tools geometry, cutting tools' materials (allowable maximum v and f), stock-workpiece geometry, workpiece material properties (amongst others, yield strength, shear strength, modulus of elasticity, unit power, and Brinell hardness), and machine type characteristics are developed using GNU/PostgreSQL database. Java programming language is used to develop the software product. To develop the prototype application, a modeling effort of the software architecture is performed by using GNU/Umbrello, a UML-Unified Modeling Language application. The implementation of process optimization in this application is based on Taylor's Tool Life formula. Iterations are performed to provide the suitable cutting parameters based on cutting power, cutting force, allowable beam (workpiece) deflection, manufacturing cost and time. The functionally-tested application has made it a prototype with prospect in becoming a very helpful tool later on for machining operators to find a set of optimized cutting parameters with consideration of several machining constraints.
