The generalized traveling salesman problem deals with "states" that have (one or more) "cities" and the salesman has to visit exactly one "city" from

The bin packing problem can also be seen as a special case of the cutting stock problem.

In this paper we investigate the one-dimensional cutting stock prob- lem with respect to the modified integer round-up property (MIRUP) and present

As the name implies, tool steel refers to a number of different high speed, carbon, and alloy steels that are used to make tools. Desirable features in tool steel include toughness, wear resistance, and strength at high temperatures. High speed steel is so-called because it is capable of cutting

is to keep replacement consumables, such as breakaway bolts on the cutting head, in stock and ready to install, minimizing downtime. Minimum stock levels should be established, and when inventory falls below that number, the part can be reordered automatically to avoid having to wait for parts from

programming of the CNC units. There were no known problems with the tightly controlled production, but it was an operation waiting for a new idea. That idea came to Pat Calabrese on a trip to Germany. "We were given a tour of a plant that had a laser cutting machine in it. The entire operation

that not to be the problem. We found that we needed to go in and perform some maintenance and realignment chores. In a 9-hr. process, we realigned the cutting head, adjusted bend mirrors and replaced mirrors that were worn. We’ve been at full speed ever since, and now, along with weekly preventive maintenance

DGC1- Don't have much to add to your fairly complete list of parameters. Since you are hand feeding the stock your apparent only slow speed limitation is to feed the stock fast enough as to not burn or char the wood and not gum up the blade. High speed rate as you stated is best determined by...

I use long rolled stainless threaded rods in my little CNC machines. I have found that they vary considerably in diameter over their length, which means that I have to run a die down them to try and get a consistent diameter. You would be shocked to see just how much material I have us...

By Herb Greenberg SolarCity, with its shares up more than 50 percent in a little more than a week, may go down as the poster child of the sizzling market for this round of nuttiness for solar stocks. Yet, as Raymond James analyst Pavel Molchanov is quick to point out, the market gains are after mixed first quarter results and second quarter guidance “that was definitely on the soft side, leading us to cut estimates for the second time this year.” Oh, and by the way, in less than 20 days, 60 million SolarCity shares, restricted since the company’s IPO six months ago, will get unlocked, Molchanov said.
