ABSTRACT:
A system and method for controlling an apparatus, in particular an apparatus for performing manufacturing operations on a work piece is described. The system uses a hierarchical series of levels of functional operations. The system has a highest level and a series of lower levels. There is a means for initiating an instruction in the highest level which results in executing of instructions in the series of lower levels until an instruction is executed to control the apparatus. A particular example consists of four levels all written as sample programming language files which are fully editable and modifiable by end users: A manufacturing operations consists of a cell or cluster of manufacturing the operations of which are controlled by the system of the invention which enables on-line tool diagnostics and simulations that can predict the effects of proposed process changes, thereby reducing the time normally required to make alterations to a process.
