I'd agree with Dave here. >> Request for a price quote from a potential client ended with a >> revelation to me that i have to find a way to decrease the production >> cost and that involves also reduction of labor time. You're right in my bread and butter zone here <G> Firstly I'd look at the lathe code, see if it can be improved on, then look at the feeds/speeds and tooling and see if that can be improved within the capabilities of the machine. The crossing point for production speed to cost is the secret. It's sometimes more cost effective to run slower and tooling last longer than to run flat out with increased tool/machine wear and more frequent insert replacement. Any good CAM program should be able to optimise the code, but I still find I can shave a little off any CAM programs job times manually. Whether they can recoup my charge for doing that within their job cycle lifetime is their problem ;) Steve Blackmore -- ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
