Tool path of lathe machine in flexible transfer lines by using genetic algorithms

Abstract

In this paper, we present a new approach for tool path generation of numerical control (NC) lathe machine tools during the development of flexible transfer lines (FTL). The approach that uses a genetic algorithm (GA) can automatically generate a tool path of the NC lathe machine tools and decides the part reverse position by just giving the dimensions of a cylindrical type of the work piece. Conventionally, this reverse position is decided by an experienced operator because it was difficult to decide automatically in the FTL. The GA approach of our system adopts the moving points of the tool path as an individual. We propose two individuals expressions. The first expression is defined by adopting an absolute value of the tool path as absolute individuals expression (AIE) and the second expression is defined by adopting the incremental value of the tool path as incremental individuals expression (IIE). After some simulations, it is ascertained that our system is useful.
