Method and device for operating a driven axle in a machine tool
First Claim
1. A method for operating a driven axle in a machine tool, in particular an injection molding machine, wherein at least two different drives operate according to different technical principles and are interconnected to form a common effective axial drive for the driven axle, comprising:
- storing performance data for each of the at least two different drives in the form of characteristic values or characteristic curves,specifying a performance profile for the effective drive,determining a performance requirement for the driven axle,based on the performance requirement, determining from the stored performance data an operational combination of the at least two different interconnected axial drives that produces the performance profile, andoperating the at least two different interconnected axial drives with the determined operational combination.

Abstract
In a device and a method for operating a driven axle in a machine tool, in particular in an injection-molding machine, at least two different drives are coupled to form a common effective drive, wherein the performance and energy consumption data for each drive are stored in the form of characteristic values or characteristic curves. To use the effective drive as optimally as possible in terms of energy, it is proposed to determine the performance requirement for the driven axle, to determine the particular operational combination of the different drives that requires the least expenditure of energy based on the determined performance requirement and to drive the drives with the determined particular operational combination.
