How do energy-efficient CNC machine tools affect energy demand?

Energy-efficient CNC machine tools contribute to this goal. In machining processes, the machining strategy also has a significant influence on energy demand. For manufacturing of lot size one, the prediction of the energy demand of a machining strategy, before a part is manufactured plays a decisive role.

How to predict energy consumption during CNC machining?

In order to develop a prediction model for the energy consumption during CNC machining, both are inevitable: the knowledge about characterization of the single elements responsible for the energy consumption during machining as well as a broader understanding of the already taken efforts in building predictive models for the energy consumption.

Can a high energy consumption time series be used in machining?

This model with its high prediction quality of the energy consumption time series could enable the energy prediction during the machining process and an online optimization of the cutting parameters in respect to a constant load of the CNC machine tool.

Can machine learning predict the energy demand of CNC machining operations?

In this paper, different machine learning algorithms, especially variations of the decision tree (’DecisionTree’, ’RandomForest’, boosted ’RandomForest’) are investigated for their ability to predict the energy demand of CNC machining operations based on real production data, without the need for dedicated experiments.

Can energy model help reduce cost in machining?

Those results prove that the developed energy model can be used to predict the energy consumption and is a valid tool to help reduce cost in machining and to give direct feedback to part designers before machining as proposed in the introduction. None. Markus Brillinger: Conceptualization, Methodology, Writing – Reviewing and Editing.

How to predict the energy demand curve of the machining process?

Although there are exceptions for specific measures and aggregates, the most accurate predictions can be achieved with ’RandomForest’ algorithm. In Fig. 7, the plot of the predictions of the energy consumption of the y axis aggregate is compared to the measurements. Hence, the energy demand curve of the machining process gets predicted accurately.
