Total precision inspection of machine tools with virtual metrology

Journal of the Chinese Institute of Engineers, 2015
The technology of virtual metrology (VM) has been applied in the semiconductor industry to convert sampling inspection with metrology delay into real time and online total inspection. The purpose of this study is trying to apply VM for inspecting machining precision of machine tools.

Virtual training for the maintenance of machine tools

AHFE International
In the course of digital change, systems and processes are increasingly being planned, adapted and tested using computers. Innovative technical aids are needed to guide staff and relieve them physically and mentally in order to cope with flexibly changing work tasks such as the maintenance of machine tools.Virtual reality (VR) offers attractive ...

Web-based implementation of virtual machine tools

Proceedings KORUS 2000. The 4th Korea-Russia International Symposium On Science and Technology, 2002
In this research, the virtual machine tool that is implemented for WWW and their associated technologies, is introduced. Also, modeling techniques to express the machine tool on Internet are introduced. The Web-based virtual machine tool can be applied for educational purposes by overcoming the site-dependency.

A Language and Tool for Generating Efficient Virtual Machine Interpreters

2004
Stack-based virtual machines (VMs) are a popular representation for implementing programming languages, and for distributing programs in a target neutral form. VMs can be implemented with an interpreter to be simple, portable, quick to start and have low memory requirements.

Substructure Coupling of a Machine Tool in Arbitrary Axis Positions Considering Local Linear Damping Models

Journal of manufacturing science and engineering, 2019
Virtual prototypes, e.g., finite element models, are commonly used to reduce the development times of a new machine tool generation. However, the accuracy of these models is often limited by their representation of damping effects and the possibility to ...

qvm: A Command Line Tool for the Provisioning of Virtual Machines

Proceedings of the 8th International Conference on Cloud Computing and Services Science, 2018
The purpose of this paper is to create and demonstrate a command line utility that uses freely available cloud images—typically intended for deployment within public and private cloud environments—to rapidly provision virtual machines on a local server, taking advantage of the ZFS file system.

Virtual Design and Optimization of Machine Tool Spindles

CIRP Annals, 2005
An integrated digital model of spindle, tool holder, tool and cutting process is presented. The spindle is modeled using an in-house developed Finite Element system. The preload on the bearings and the influence of gyroscopic and centrifugal forces from all rotating parts due to speed are considered.

Design and Implementation of Resource Management Tool for Virtual Machine

2012
To support real time task in a virtual machine, hypervisor have to monitor system resource and provide exact resource for real time task. There are several monitor tools running on virtual machine, however, it has limitations on supporting detailed information for monitoring real time workload, performance degradation and difficult for controlling user

An Integrated Virtual Engineering Environment for Machine Tools

2004
High-speed machine tools ask for small settling times and overshoots of the tool motions, and hence light-weight moving parts and high-performance control systems. To obtain such high performance, the classical rule of thumb that the control bandwidth should be less than half of the first structural eigenfrequency of the machine cannot be adhered to ...
