The Development of the Machine-Tool Dynamic Passport Based on Neural Network Modeling of its Working Space Using nVidia CUDA Technology and Deep Learning Approaches
The authors propose a method of developing an individual dynamic passport of a machine-tool that allows them to determine optimal modes of operation and setup of the machine in an automated mode. The method is based on identifying the relationships between the input parameters of the cutting process using experimental data (mode of cutting, machined material, workpiece fixing method, tool geometry, geometric parameters of the workpiece) and the output parameters (amplitude, frequency, and fractal dimension of the attractor) using a neural network adapted to the regression analysis. After training, the regression neural network model of the cutting process is created, that is able to simulate any combination of the input parameters of the cutting process and analyze the output values, therefore determining the margin and area of the system stability in a wide setting range. The resulting neural network model reflects the dynamics of the specific equipment that leads to high output rates of machining without compromising quality. The use of nVidia CUDA parallel computing algorithms significantly accelerates the learning process of the neural network, and therefore makes it possible to use them in operational diagnostics in production systems.
