Abstract
The rising amount and complexity of machine tool control software forces developers and vendors to increase software quality assurance measures, especially system regression tests. These tests are mostly conducted manually at real machines and thus error-prone, expensive and time-consuming. This paper discusses the state of the art in machine tool control software testing and proposes a new approach for the automated test of machine tool control software. Its outstanding feature is a manufacturer-independent test environment that makes it possible to test control software on different control types with minimum overhead. The approach bases on ahardware-in-the-loop simulation system and implies a concept for a uniform access to the multitude of communication interfaces of todays controls. Furthermore, the paper shows the problems that make such a tool difficult to define and gives a concept for implementation.
