Title:
CONTROL SYSTEM OF A NUMERICAL TOOL MACHINE WITH A REUSABLE SOFTWARE STRUCTURE
Document Type and Number:
WIPO Patent Application WO2001027703
Kind Code:
A3
Abstract:
In order to create a reusable software structure for a numerical tool machine control program, said control program is divided up into an application-dependent part and an application-dependent part. According to the invention, the application-independent part of the software comprises several framework classes which contain generic functions, e.g. for a human-machine interface, a geometry processor, an interpolator, a movement processor and a memory programmable control part. In the application dependent part, application specific functions are implemented in derived classes which can be derived from the classes of the application-independent frameworks. Instances are formed from the derived classes containing the data for the implemented functions and are designated as objects. Information is exchanged via communication channels existing between said objects.
