  2. Free machining steel - Wikipedia

    en.wikipedia.org/wiki/Free_machining_steel

    Free machining steel costs 15 to 20% more than standard steel, but this higher cost is offset by increased machining speeds, larger cuts, and longer tool life. [1] The disadvantages of free machining steel are: ductility is decreased; impact resistance is reduced; copper-based brazed joints suffer from embrittlement with bismuth free machining ...

  3. Broaching (metalworking) - Wikipedia

    en.wikipedia.org/wiki/Broaching_(metalworking)

    The semi-finishing teeth provide surface finish and the finishing teeth provide the final finishing. The finishing section's RPT (t f) is usually zero so that as the first finishing teeth wear the later ones continue the sizing function. For free-machining steels the RPT ranges from 0.006 to 0.001 in (0.152 to 0.025 mm). For surface broaching ...

  4. Machinability - Wikipedia

    en.wikipedia.org/wiki/Machinability

    Machinability is the ease with which a metal can be cut permitting the removal of the material with a satisfactory finish at low cost. [1] Materials with good machinability (free machining materials) require little power to cut, can be cut quickly, easily obtain a good finish, and do not cause significant wear on the tooling.

  5. SAE steel grades - Wikipedia

    en.wikipedia.org/wiki/SAE_steel_grades

    Type 303—free machining version of 304 via addition of sulfur and phosphorus. Also referred to as "A1" in accordance with ISO 3506. [6] Type 304—the most common grade; the classic 18/8 (18% chromium, 8% nickel) stainless steel.

  6. Bar stock - Wikipedia

    en.wikipedia.org/wiki/Bar_stock

    There are four types of materials available: O-1 tool steel, A-2 tool steel, A-6 tool steel, and 1018 steel (low-carbon or low-carb steel). Lengths are either 18 or 36 in (457 or 914 mm) long, various widths up to 16 in (406 mm) are available, and thicknesses range from 1 ⁄ 64 to 2.875 in (0.40 to 73.03 mm).

  7. Monel - Wikipedia

    en.wikipedia.org/wiki/Monel

    Monel alloy 405, also known as Monel R405, is the free-machining grade of alloy 400. [24] The nickel, carbon, manganese, iron, silicon & copper percent remains the same as alloy 400, but the sulfur is increased from 0.024 max to 0.025-0.060%.

  8. Materials for use in vacuum - Wikipedia

    en.wikipedia.org/wiki/Materials_for_use_in_vacuum

    Not all alloys are suitable; e.g. the free-machining 303 steel contains sulfur, which tends to outgas. Alloys with good weldability under argon arc welding are usually chosen. 304 stainless steel is a common choice of a stainless steel. 304L stainless steel, a low-carbon variant of 304 steel, is used for ultra-high vacuum systems.

  9. Freeform surface machining - Wikipedia

    en.wikipedia.org/wiki/Freeform_surface_machining

    Freeform surface milling. In manufacturing, freeform surface machining refers to the machining of complex surfaces that are not uniformly planar. The industries which most often manufactures free-form surfaces are basically aerospace, automotive, die mold industries, biomedical and power sector for turbine blades manufacturing.
