Machining Waste Streams

Noise and Vibration Page

Vibrations are a result of motion within the machining process. This motion naturally causes disturbances in the air, causing noise. This noise and vibration is generally an unwanted byproduct of manufacturing which has a significant effect on the capability of the manufacturing process, and also an environmental effect.

Many machine tools today are isolated from the floor with special mounting devices to limit their vibration transmission. This is primarily done to prevent disturbance of other machines. Machines are also enclosed by rigid structures lined with acoustic material to deaden sound transmission. This is primarily done to protect the workers from hearing loss. This is no small concern. Shops with high noise background levels (e.g., stamping plants) must undertake steps to conserve the hearing of the workers. Measures include mandatory hearing protection usage, annual hearing examinations, and limited exposure to exceptionally high noise operations, such as some forging operations. Release of compressed air is of real concern, as it is one of the leading causes of high noise levels in many plants

While noise and vibration effects are primarily limited to the confines of the plant, noise will travel outside of the plant and may have an effect on wildlife, making an area less hospitable for animals. Vibrations have an effect on machine tool and manufacturing processes, leading to scrap and worn out machine tools entering the waste stream.
