Gears are mechanisms that mesh together via teeth and are used to transmit rotary motion from one shaft to another. Gears are defined by two important items: radius and number of teeth. They are typically mounted, or connected to other parts, via a shaft or base. Radius: The gear radius is defined differently depending on the particular section ...

This page tries to describe the flavour of G-codes that the RepRap firmwares use and how they work. The main target is additive fabrication using FFF processes. Codes for print head movements follow the NIST RS274NGC G-code standard, so RepRap firmwares are quite usable for CNC milling and similar applications as well.See also on Wikipedia's G-code article.

Scale on a mesh is relative. A scale of (1.0, 1.0, 1.0) means the mesh will display as the exact size specified in the mesh file. A scale of (1.0, 1.0, 2.0) means the mesh will show up twice as tall, but the same width/depth.. If the mesh_use_embedded_materials flag is set to true and the mesh is of a type which supports embedded materials (such as COLLADA), the material …

mill grinding rate over the material's grindability as measured in the lab. Mill percent solids optimization has thusly been achieved (McIvor et al., 2000). For media sizing, maximizing the mill grinding rate on a given ore is equivalent to maximizing the mill grinding efficiency. Ores of different grindability will be part of the discussion.

The mesh in a wooden sieve might be made from wood or wicker.Use of wood to avoid contamination is important when the sieve is used for sampling. Henry Stephens, in his Book of the Farm, advised that the withes of a wooden riddle or sieve be made from fir or willow with American elm being best. The rims would be made of fir, oak or, especially, beech.

The term 'Mesh' is used to describe the size of an abrasive particle. In some instances, such as with Aluminum Oxide Grit or Silicon Carbide Grit, a single number is used.This does not mean every particle in that product is exactly that size but rather than mesh size indicator is approximately the mean or average size of the range of particles in that grade.
