We describe an integrated system for NC machining of parts made of multi-patch surfaces. The system enables the user to generate tool paths based on practical metrics such as length, curvature and number of tool paths. We also describe two methods for interfacing with commercial CAD/CAM packages.

This paper describes an interactive computer-aided assembly planning system that greatly reduces the human input required to construct assembly plans. The system takes a dual approach. First, most assembly operations are validated automatically from the CAD models of the as-sembly's parts using simple, fast techniques. Second, with each query the user is allowed to identify a set of parts that ...

The number of people who design typefaces has drastically increased in the last twenty years. However, not all typefaces work as they should, i.e., as a group of characters with shared attributes. We present a tool for helping type designers in their creative process, which explores the anatomic relations among characters of a typeface. Having computer-aided design as a goal, our tool helps in ...

Two major programs aiming at supporting academic education and technology transfer to SMEs in the field of microelectronics have been launched in mid-95 by the Commission of the European Communities (EC). The EUROPRACTICE program provides basic services including silicon foundries, training ariNd access to MCMs, microsystems and CAD so&are, while the FUSE program encourages companies to use a m...
