Noise issue and worried about it if i have workshop built any views or help please

Hi Suesi,

I think you may be misunderstanding what's being meant when noise is mentioned in some threads.?

Most are NOT talking about the DB noise of the machine but the Electrical interference "noise" coming from various sources which affect the running of the machine.

Resonance is another term you'll see used and while this is related to machine vibrations etc it's mostly higher frequency resonance which affects motors and drive performance and not how much the machine actually vibrates to the feel or touch.

If I'm wrong then sorry and ignore my ramblings. . . Lol

Regards machine DB noise then most of the noise comes from the spindle/cutting tool and material type. Different materials have higher or lower sound levels and vibrations depending on density, RPM, DOC & Feed rates being cut at etc.
Stiffer machines can cut deeper and faster but make more noise/vibrations so it's not easy to compare DB noise unless like for like machines.

Personally I'd just build the machine you want without worrying about noise and deal with noise if it's an issue by building an enclosure with sound deadening materials to a DB level that's acceptable to you.

Hi Jazz,

Thank you very much for the reply. I was on the right track for a change talking about the DB noise produced i.e. machine start up run down and like you say cutting! I have read on here that someone used polystyrene sheets on the walls. The trouble is say I have half a dozen machines I didn't want to box each in individually but more rely on the workshop to deaden the noise right down. I would like to be pretty sure about noise as we had a complaint about a radio not so long ago and it wasn't even that noisy! I have tried to look for case studies for use of machinery etc but nothing jumps out at me. I imagine noise is a problem that a lot of us have. I am thinking about buying some special foam and having a small scale test. http://www.ebay.co.uk/itm/12-x-Studi...item566cf2e634

Many thanks
