Baumüller Smart Value
Get more out of your drive technology with IoT: Baumüller Smart Value is all about the added value that smart drive technology gives mechanical engineers and machine operators. Baumüller Smart Value enhances the scope of our servo drives: It takes existing data, such as power, current, torque, speed and position, and provides users with important additional information (e.g. machine operating status) or decisions are made directly in the drive to prevent machine failures. The same can be said of the associated design software, which ensures that the motor / controller combination is optimally dimensioned for the respective application and the controller is parameterized. In addition, the design can be immediately verified and optimized on the digital twin using simulation technology.

The problem

A decisive criterion for grinding machines is the speed accuracy. The workpiece can be machined optimally with only a small difference in the grinding process. Due to the large grinding rolls and vibratable coupling elements, it is often difficult to make the controller setting at the machine.

The challenge

Use Case 3: Grinding machine

The speed accuracy can frequently only be achieved by time-consuming work during the commissioning. The technical implementation must be perfect, otherwise the machine can be damaged.

The solution

ProSimulation enables the drive behavior to be tested virtually. This enables new settings to be tested quickly and easily, without running the risk of damaging the machine.

In this specific example, the settings found in this way helped to increase speed accuracy in the production process by a factor of 7. This meant a significant improvement of the grinding result. The virtual data set optimization produced a large reduction in commissioning time, since the settings could be tested quickly and easily in ProSimulation even without the real machine. Furthermore, the system limits could be explored through to overloading and swinging up, without running the risk of affecting the mechanics.

The modeling of the grinding machine was set up purely using models from the integrated library. The vibrating properties of the mechanics can be entered directly.
