Abstract
Machining of stamping tools for the automotive sector is a research topic of large interest. The industry is continually searching for strategies, machines, tools and parameters to improve machining performance, to increase the quality of the machined surfaces, and to reduce the total cost of construction and tryout phases of the stamping tools. The CNC machines allowed large developments in the machining sector. However, in order to explore the full potential of these machines in the cases of complex geometries such as automotive tools, the Computer Aided Manufacturing (CAM) software must be used. The CAM software are a powerful solution that enable a large number of analyses simulating different strategies allowing to choose the best combination of operations, tools and parameters of a given toolmaker facility, as well as it can be a compelling argument to drive new investments to increase the competitiveness of the toolmaking industry. The Brazilian government program Rota 2030, possesses a line of research and development called Ferramentarias Brasileiras Mais Competitivas (FeB+C), and within the context of this line, the MISCAE Project aims to investigate the applications of simulation tools to increase the competitiveness of the Brazilian toolmaking industry. This paper consists in one of the contributions of the MISCAE Project in the field of CAM simulations to develop the Brazilian industry. The objective of this paper is to perform a series of studies comparing different machining strategies applied to automotive stamping tools using the software HyperMILL, evaluating the processes commonly used in contrast to the most advanced resources proposed by the software. The combinations of different machines (3-axis and 5-axis), operations, cutting tools and parameters will be assessed, and the following parameters will serve as metrics: machining time per operation and the number of operations. As a result, a benchmark is provided for the Brazilian tookmaking sector.
