Understanding cutting equations | Cutting Tool Engineering

Cutting speed calculations might well be the most important ones. They are easy to use and, with a little explanation, easy to understand. The cutting speed of a tool is expressed in surface feet per minute (sfm) or surface meters per minute (m/min.). Similar to mph for a car, sfm is the linear distance a cutting tool travels per minute.

Slab – Minecraft Wiki

Slabs are half-height versions of their respective blocks. Stone-type slabs require a pickaxe to mine. Cut copper slabs require at least a stone pickaxe. Wooden slabs can be mined with anything, but an axe is quickest. Unlike stairs, many stone-type slabs have different hardness values (and thus, breaking time) compared to their full-block counterparts. Most slabs drop themselves when broken ...

A lower side of a rotatable grindstone spindle is connected directly to a PZT (Piezoelectric element). By changing electric drive supplied to the PZT, reciprocating movement can be applied to the grindstone through the grindstone spindle in addition to rotational movement. As a result, the grinding locus of an abrasive grain of the grindstone on a taper surface of a workpiece becomes a sine ...

Asphalt Pavement Construction - Asphalt Institute

For example, a mix containing ½-inch NMS stone should be placed at a compacted depth of at least 1-½ to 2 inches. If a ½ -inch top-size mix is placed at 1 inch compacted depth, the mat may pull and tear and the stones may be broken by the rollers. Thus, the "depth of paving" does influence the ability to obtain proper compaction.
