The ability to perform machining operations in a comprehensive simulation environment and to obtain realistic predictions of its outcome in terms of workpiece attributes (dimensional tolerance, form, and surface finish) and process capabflities is the vision motivating this proposal. An initial framework for the realization of this capability, epitomized by the designation Virtual Machine Tool (VMT), will be defined. The envisioned VMT environment will ultimately allow machine tool builders to evaluate alternative machine designs and configurations, and will assist machine tool users to predict the achievable workpiece attributes during planning, selection, and use of' metal cutting machine tools. The underlying assumptions, interrelation between the necessary functions, and the envisioned methods and approaches to the computational simulation of the functional elements of the VMT will be addressed. The principal emphasis will be on fundamental issues related to the integration of machine and process related funttions, and on the development of predictive models for workpiece attributes and process capability measures that are essential missing ingredients of the VMT concept. The outcome, consisting of prototype code for the characterization, visualization, and mapping of workpiece attribute deviations from the nominal, will be experimentally verified on the example of end milling, drilling, and tapping operations.

在综合模拟环境中执行加工操作的能力，并在工件属性（尺寸耐受性，形式和表面表面和表面表面和表面表面）方面对其结果进行现实预测和过程capabflities，这是激励此提案的愿景。 将定义由名称虚拟机（VMT）表现出来的实现此功能的初始框架。 设想的VMT环境最终将允许机床构建器评估替代机器的设计和配置，并将帮助机床用户预测在计划，选择和使用“金属切割机器”期间可实现的工件属性。 基本的假设，必要函数之间的相互关系以及VMT功能元素的计算仿真的设想方法和方法将得到解决。 主要的重点将放在与机器和过程相关的功能集成以及工件属性和过程能力指标的预测模型的开发以及VMT概念中必不可少的成分的基本问题上。 该结果由原型代码组成，用于与名义差异的特征，可视化和映射的映射，以终端铣削，钻孔和攻击操作的例子进行实验验证。
