Virtual Cutting Tool Management System for Milling Process

IJCSNS, 2010

Information of cutting tools is very important for the effectiveness of cutting process. Previously, traditional search methods 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 type, 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.

Cad/Cam System for Virtual Machining, Machine Tool Mock-Up and Knowledge Base Machining

This application with ESPRIT software has been developed in the work shop of the mechanical department of INSA-Lyon. Because of the usual use in education and in industries of many CAD software systems such as Catia, Pro Eng, IDEAS etc., was decided 3 years ago to implement a powerful CAM software system completely independent of these. The objectives were: friendly data communication with CAM system; to increase the development of applications in the production and manufacturing fields; to develop formation and training for education and industries with the help of information and communication technologies. This paper rapidly presents the implementation and the actual exploitation. In paragraph 1, ESPRIT software and the used functions are presented. The CAM formation of the INSA mechanical engineers is detailed in paragraph 2. The paragraph 3 presents the future developments. The KBM (Knowledge Based Manufacturing) function is described so as his use for the process planning. To conclude, the benefits expected for education and industry with virtual machining and e-manufacturing are highlighted.

Virtual Manufacturing for Training and Education

Proceedings of the 2005 …, 2005

A virtual manufacturing laboratory for educating students and practitioners on advanced manufacturing is proposed. The particular environment for simulating CNC milling is developed. The environment provides the following training functions for students: (a) access to a fully-functional virtual CNC milling machine (FADAL ® VMC 3016L), (b) training on the key operating procedures of the CNC machine, (c) a lecture describing the components of the milling machine, and (d) a lecture describing the concepts of CNC milling. The environment is driven by three software modules: (1) a CNC Milling machine simulator, (2) a virtual-environment display engine, and (3) an intelligent-agent engine. The three modules run on a single computer in a seamless web-based framework. This will allow the student to access and run the virtual CNC machining center on the web. The CNC Milling machine simulator simulates the machine physical components including the spindle, stages, manual controller interface, and controller software. It also simulates the cutting process including cutting tool motion, workpiece geometry during cutting, cutting forces, machining sounds, and chip-formation. These capabilities are described below. The same paradigm can be used to provide training on other machine tool controllers as well as CNC manufacturing processes.

Simulation of Working Process and Tool Modelling on CNC Machines by Win3D-View Software

2003

The urge for achieving highe productivity of domestic production alongside broadening o poduct assortment conditions more intense application of numeical NC and compute numerical control CNC machines and of basic devices for automation of small serial and medium serial production as dominating ways of production. It is, thereore easy to undestand the attention being paid to installing a bigger number of CNC machines in the production process in the last few years, whose development is in close connection to the development of electronics and computing technique. Computer controlling presents the basic automation of a working process. All the pieces of information necessary for controlling and working process realisation that are programmed are systemised and coded in the form of a programme. They are entered in the memory of a controlling system. The basic elements of the design process in industrial practice are graphical simulations of a working process on CNC machines, which are most frequently presented by an independent software, depending on the applied control type. The independent Win3D-View software, version 2.00 with basic characteistics and possibilities presented in the paper on the example of turning has also been developed for that purpose. The software has been created for the purpose of the 3D graphical simulation of turning and milling on CNC machines and it is most frequently integrated with WinNC and WinCTS software. The working process that is graphically simulated on the CNC machine is previously programmed in SINUMERIK 810T controlling format (or in one of the following types of control: SINUMERIK 820T, GE FANUC Series 0-TC, EMCOTRONIC T2). The graphical simulation, primarily designed for industrial use, realistically presents the working process, unmachined part, tool, clamp device, and different views and sections of a processing piece. A library with standard tools is formatted during the software installation, from which all the tools necessary for the processing are chosen. It is also possible to create one’s own tools for the 3D simulation. The paper presents a modelling procedure of a typical tool for turning.

Simulation of a workpiece in CNC milling machine on the basis of G and M code based NC programming

The assisting technology of CNC milling machine is inaugurating the virtual machining platform, correcting NC program and process simulation and optimization, which can fabricate the efficient machine technology come true. The paper represents the G and M code based numerical control (NC) programming and real time 3D virtual simulation of workpiece in CNC milling machine (DENFORD MICROMILL, 2000), by using machine simulator. Machine simulators namely Denford Virtual Reality CNC milling.micromill and CncSimulator Pro. are used. The workpiece is designed through the MasterCAM (QuickCam) software (CAD/CAM Family) which reflects a milling process, setting all the movement trajectory of cutting tool over that workpiece using polynomial interpolation. Intelligent CAD/CAM generates NC program for a particular case along with a G and M code based NC program is also developed for a separate workpiece. The simulators used enable development of complex machine troubleshooting scenarios that are not feasible on real equipment.

Development of Web-based CAM system

The International Journal of Advanced Manufacturing Technology, 2006

In this paper, we present the methods to develop a Web-based CAM system that is capable to dynamically simulate machining processes in solid graphics form through the Internet. Methods include the virtual reality modeling language (VRML) structure to represent the machined workpieces progressively on Web, the definition and storage of workpiece information upon the request of users, the CORBA-based interpretation of NC part programs, and algorithms for efficient machining simulation. Based on these methods, an Internet-based CAM system is implemented at http://isd.korea.ac.kr. Using the Web-based CAM system, public users can simulate machining processes by for their own NC part programs.

A new web based STEP-NC converter (W-STC) for simulation & NC machining

Design Engineering, 2021

STEP-NC (ISO14649) is an enhancement to STEP (ISO 10303) for operating NC machines upon which many researchers developed many systems and platforms. Unlike traditional manufacturing processes, STEP-NC compliant manufacturing enables homogeneity & interoperability across various stages. Many researchers developed various converter tools which convert STEP-NC file into other formats to enable this homogeneity & interoperability. The present work reviewed many of these existing converters for their conversion capabilities. These converters mainly aim to convert STEP-NC files into either 'G-code' (for CNC operations) (or) to 'XML' (for exchange of information) (or) to any other type of controller program. However, minimal efforts were made to convert the STEP-NC file into any simulation file formats for CAM needs. So, the present work proposed and developed a new web-based converter meeting the needs of both CAM & CNC. Developed 'Web based STEP-NC Converter (W-STC)' works as a web application and can serve as a cloud manufacturing service for global users via internet. As a result, cloud users can import STEP-NC file as input, verify working steps, key entities that influence the tool path, and generate '.jscad', '.nc' files against each working step. The developed converter works for all the five milling operations mentioned in 'ISO 14649, Part 11'. A case study with the 'plane finish milling' operation is considered in the present paper to describe the working of this new 'W-STC' as a CMfg service.

The key elements of the environment are: (a) textured 3D photo-realistic virtual models of the machines and lab; (b) machine simulator for the machines' controls and moving parts; (c) semi-empirical model of the machining operation; (d) hierarchical knowledge-base for process training; (e) unstructured knowledge-base for lecture delivery; (f) natural-language human-like intelligent virtual tutors. Applications of the AVML include: training students to operate manufacturing machines in a safe environment, allowing students and researchers to view and interact with highly accurate physical simulation of manufacturing machines, and optimization of the manufacturing process plan by testing various plans on the virtual machine before actual machining. The virtual training environment will significantly reduce the cost and increase the accessibility and safety of advanced manufacturing training.

Prototype Development of Milling Machine Using CAD/CAM

2015

The development of unmanned machining systems has been a recent focus of manufacturing research. The conventional milling machine removes metal with a revolving cutting tool called a milling cutter. For this, CNC machines are in use. CNC machine operates on part program. This program includes several G-codes and M-codes. This program is generated by skilled operators. This may cause error in geometry. Also increases labor cost. Thus new technology of milling operation is conceptualized to reduce these problems using CAD/CAM. In this, firstly part design is created in CAD software like CATIA, ProE etc. This part design is fed in CAM software. Accordingly, coordinates forms. Also program is generated. According to that program, cutting tool operates to produce
