摘要:

HITEST is the first test generation program to capture and use the test engineer's knowledge to allow it to solve the test generation problems caused by complex digital components. The test engineer supplies useful information on the operating modes of component parts of the circuit and HITEST uses this information, together with its innate ability to analyse combinational logic, to allow it to construct test vectors. In case of difficulty—for example, through corrupt or missing data from the test engineer—HITEST interacts with the test engineer to allow the problem to be solved in the most efficient way. This paper describes HITEST and gives examples of its use.

摘要:

This article outlines experience gained during the joint development of COMPASS, a three-dimensional CADCAM system for sheet metal ductwork, by Henry Hargreaves and Sons Ltd. and CADCentre Ltd. It shows how a culture gap can exist between the engineering team and the CAD software development team and how this gap can be bridged for successful collaboration. It concludes with a number of lessons learned which may also be useful to other engineering companies and software developers about to embark on computer-aided design.

摘要:

The impact of CADCAM systems on the shopfloor depends on how they are introduced. This is an account of their early development within a small mechanical engineering company, where their value was quickly recognised and accepted.

摘要:

Many manufacturers have already invested in computer-aided design equipment for the layout of printed circuit boards. The CAD database can be used to generate information for automated test and computer-aided repair, resulting in further dramatic savings in time and labour costs.

摘要:

During the last year, staff at Manchester Polytechnic have been conducting an investigation into the effective use of CADCAM, which has involved collaboration with a manufacturing company in the North West of England. This article reviews two roles for data (database and data stream) as the focus for integration of CADCAM systems and considers the application and extension of these roles within the specific organisation being studied.
