abstract = "CAD/CAM systems are nowadays tightly connected to
ensure that CAD data can be used for optimal tool path
determination and generation of CNC programs for
machine tools. The aim of our research is the design of
a computer-aided, intelligent and genetic algorithm(GA)
based programming system for CNC cutting tools
selection, tool sequences planning and optimisation of
cutting conditions. The first step is geometrical
feature recognition and classification. On the basis of
recognised features the module for GA-based
determination of technological data determine cutting
tools, cutting parameters (according to work piece
material and cutting tool material) and detailed tool
sequence planning. Material, which will be removed, is
split into several cuts, each consisting of a number of
basic tool movements. In the next step, GA operations
such as reproduction, crossover and mutation are
applied. The process of GA-based optimisation runs in
cycles in which new generations of individuals are
created with increased average fitness of a population.
During the evaluation of calculated results (generated
NC programmes) several rules and constraints like rapid
and cutting tool movement, collision, clamping and
minimum machining time, which represent the fitness
function, were taken into account.
A case study was made for the turning operation of a rotational part. The results show that the GA-based programming has a higher efficiency. The total machining time was reduced by 16percent. The demand for a high skilled worker on CAD/CAM systems and CNC machine tools was also reduced.",
