Development of a Method to Determine Cutting Forces Based on Planning and Process Data as Contribution for the Creation of Digital Process Twins

A digital process twin unifies information from planning and manufacturing of a machining process.Calculation and technological models allow the prediction of further information, which normally is not provided.The work shows the recording of both data sources and creation of a digital process twin for a milling application.Further the usage of technological models is shown at the example of cutting force calculation based on drive currents in combination with a material removal simulation.Also the expansion of digital process twin information for further usage in calculations and visualizations is shown on the example of a part with a high-performance material of the aerospace industry.
