As the product life cycles become shorter, and the product variety increases, it has become crucial to minimize the lag period between the start of a product's design and the time it is manufactured. It is also crucial to be able to produce products in small to medium quantities in a cost effective manner with high quality. The objectives of this project are to develop a qualitative model of geometry and structure, a new case-based method for construction of manufacturing process plans for three dimensional objects, and new representation and reasoning methods for recognition of features and modeling of features defined by the users. Investigation will be performed and a computer based environment for integrated issues will be developed. The computer based system will be tested on different sets of components, and will be used to assess the capabilities and limitations of the underlying models. ***

随着产品生命周期的缩短， 随着品种的增加，最大限度地减少滞后期变得至关重要 从产品设计的开始到 制造的。 能够生产出产品也是至关重要的 以成本效益高的方式， 质量. 该项目的目标是开发一个 一种新的基于实例的几何和结构定性模型 一种制造工艺计划的编制方法 三维对象，以及新的表示和推理方法 用于识别特征并对由 用户. 将进行调查，并基于计算机 将为综合问题创造环境。 计算机 基于的系统将在不同的组件上进行测试， 将被用来评估的能力和局限性， 基础模型。 ***
