Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.
where is the tap drill size, is the major diameter of the tap (e.g., 3 ⁄ 8 in for a 3 ⁄ 8-16 tap), and / is the thread pitch (1 ⁄ 16 inch in the case of a 3 ⁄ 8-16 tap). For a 3 ⁄ 8 -16 tap, the above formula would produce 5 ⁄ 16 , which is the correct tap drill diameter.
ISO 965 (ISO general purpose metric screw thread—tolerances) is an International Organization for Standardization (ISO) standard for metric screw thread tolerances. [1] It specifies the basic profile for ISO general purpose metric screw threads (M) conforming to ISO 261.
High-speed steel (HSS or HS) is a subset of tool steels, commonly used as cutting tool material. It is superior to high- carbon steel tools in that it can withstand higher temperatures without losing its temper (hardness).
A patch of speed tape on a United Airlines Airbus A319. Speed tape is sometimes used to protect sealant while curing, [4] or to patch non-critical components of an aircraft. [1] It can also be used for patching bullet damage to combat aircraft. [5] [6] Use of speed tape should be authorized by engineering teams, and has to comply with certain ...
All along the post, along the spine, there are studs or nubs that prevent the barbed wire or mesh from sliding up or down the post. They are generally designated as 1.01, 1.25 or 1.33, referring to the weight in pounds per lineal foot. They are commonly painted with a white tip on top; white improves the visibility of the fence line.
There is no doubt that if a bearing is to be highly loaded in relation to its size, a high-tin alloy is desirable; whereas for much lower-speed work and less heavily loaded bearings, a lead-based Babbitt may be employed and is far more economical. Surface speed of the shaft (the number of feet traveled per minute by the shaft circumferentially):
Is it correct to pluralize them, or should it be speed and feed? Wizard191 19:11, 1 December 2008 (UTC) Either one would work, but I vote for "speeds and feeds" because it is a well worn set phrase. — ¾-10 01:31, 2 December 2008 (UTC) That's what I was looking for. I'm no machinist, so I'm not sure what the common terminology is.
