| Brinell Hardness Test Equation and Calculator |
| The Brinell scale characterizes the indentation hardness of materials through the scale of penetration of an indenter, loaded on a material test-piece. It is one of several definitions of hardness in materials science. |

| 3D Metal Printing Direct Metal Laser Sintering (DMLS) |
| 3D Metal Printing Direct Metal Laser Sintering (DMLS)- Direct metal laser sintering (DMLS) is an additive metal fabrication technology, sometimes mistakenly referred to as selective laser sintering (SLS) or selective laser melting (SLM). This process utilizes a 3-dimensional CAD model, creating a file which is then forwarded to the software utilized by the machine. The direct metal laser sintering machine makes use of a powerful fiber optic laser. |

| ISO Surface Roughness Symbols Terminology |
| The principal ISO standard that specifies syrface roughness is ISO 1302 and defines the surface roughness symbology and additional requirements for engineering drawings. The details in ISO surface finish standards relate to surfaces produced by abrading, casting, coating, cutting, etching, plastic deformation, sintering, wear, erosion, and some other methods. |

| How to use a Surface Roughness Comparator |
| How do I use a surface roughness comparator? Surface roughness comparators are used within industry to measure or verify the as-manufactured surface finish (roughness) of a part or assembly. Comparators are selected and used based on the manufacturing process used to create a particular surface finish. Industry standard manufacturing specific roughness comparators are available for the following processes: |

| Sand casting Vacuum Molding V-Process |
| Vacuum molding (V-process) is a variation of the sand casting process for most ferrous and non-ferrous metals, in which unbonded sand is held in the flask with a vacuum. |
|
| Turning lathe cutting tool forces |
| Tool forces vary with cutting speed, feed rate, depth of cut and rake angle. Force may be measured experimentally by using a 'cutting tool dynamometer' in which the tool is mounted on a flexible steel diaphragm and its deflections in three planes measured by three electrical transducers. |
