A series of tutorials describing some engineering science concepts underlying the development of manufacturing process models has been developed. The tutorials are available over networks so that access is easy. There are two unique aspects of the tutorials. One is the use of computer-independent software so that interactive exercises run on the user’s computer. This makes for fast response to user input and so useful interactive exercises are possible. The other different aspect is the presentation of process models in a non-typical way. Interactive exercises which call for the user to vary process parameter values, observe the effects on process performance and deduce the form of the process model are used. An example of one such computer-based tutorial is described — chip formation in machining. A world wide web location of the tutorial is provided so that individuals can use and evaluate the approach taken to presenting engineering science concepts and process models, http://www.menet.umn.edu/klamecki.
