16 Types Of Steel Defects: Pay Attention When Choosing ...
Because porosity has a certain effect on the performance of steel, tool steel has strict requirements on the allowable porosity level. Figure 1 and Figure 2 are φ90mm W18Cr4V (abbreviated as W18) steel raw materials, forging porosity and porosity cracking patterns (heat etching with 1:1 HCl).
SFM to RPM [ Easy Guide to Surface Speed / SFM in Machining ]
The goal of surface speed is to provide a single quantity that can help determine the best spindle rpm for every cutter type, no matter whether it's on a lathe or mill. Sounds like a tall order, but it's really pretty simple. Those cutting edges don't know whether they're on a lathe or a mill.

OLD TOWN, Maine (AP) — A Maine paper mill is asking local residents for cardboard to turn into packaging because of the rising cost of the raw materials it typically uses. ND Paper in Old Town uses cardboard and corrugated containers to create pulp that is later used to make packaging.
Calculating Your Cut Settings: Basic Feeds and Speeds ...
A securely-clamped piece of material can handle more aggressive feeds and speeds because the bit is less likely to react to resistance caused by the material. If your material is not clamped securely on all sides, it is more prone to movement during a carve. This can result in broken bits, the machine carving off-path, and other carving errors.
Why the lumber shortage? And what can contractors do about it?
While material delays are common on custom builds, they're far less common when it comes to basic framing lumber. This is the first time that many contractors have been unable to get basic materials. And when supply is down, prices inevitably rise. According to one estimate, the lumber shortage is adding $14,000 to the cost of home construction.

Heat Treating of Copper and Copper Alloys
Because solution and diffusion of the zirconium occur rapidly at the solution treating temperature, holding at temperature is not required. Aging is done at 500 to 550 o C (930 to 1020 o F) for 1 to 4 h. If the material has been cold worked, following solution treating, aging temperature may be reduced to 375 to 475 o C.

Dealing with a Materials Shortage | Production Machining
Now that the market has started back up again, the mills have not caught up with production levels of 2007 and 2008 to meet the demand. There is a shortage for certain grades and certain materials, but there are other materials that have been less affected by shortages. I think the materials market is at about 80 percent of what it was in 2008.

CNC Router Aluminum Cutting: 11 Easy Tips for 2021
If you go too slow on your feedrate, you run the risk of making your tool rub rather than cutting. This is a much bigger risk for CNC Router users than mill users simply because the spindle is going so fast. In order to maintain recommended chip loads with rpms that high you'll have to keep the cutter moving smartly.

What is Compression Force? | Tekscan
Compression force (or compressive force) occurs when a physical force presses inward on an object, causing it to become compacted. In this process, the relative positions of atoms and molecules of the object change. This change can be temporary or permanent depending on the type of material receiving the compressive force. There can also be different results …
