Investigation on Noise Reduction During Cutting of High-Strength Materials Based on Machine Acoustic Simulation

The increasing use of high-strength materials in sheet metal processing results in challenges for cutting presses. The required cutting force increases with the strength of the material. After material separation, a sudden release of the energy stored in the machine leads to intense system vibrations and noise emission. Noise protection and reduction solutions such as machine cabins or active vibration damping systems are expensive, require much space or frequent maintenance. Due to this, forming machines must be acoustically optimized. In this article, selected structure measures for the machine-side noise reduction are derived and evaluated in the context of simulation studies using an acoustic machine model.
