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.
Machining is a form of subtractive manufacturing, [1] which utilizes machine tools, in contrast to additive manufacturing (e.g. 3D printing), which uses controlled addition of material. Machining is a major process of the manufacture of many metal products, but it can also be used on other materials such as wood, plastic, ceramic, and ...
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). This property allows HSS to cut faster than high carbon steel, hence the name high-speed steel.
The company developed the first drop-tank wire EDM in 1994, [6] and HQSF (High-Quality Surface Finish) technology with patented uSc additive in 1996, [6] increasing the ability to finish parts without hand polishing when using a ram EDM. In 2003, Makino developed the first conventional horizontal wire EDM that automatically threads and machines ...
Ultra-high speed grinding (UHSG) can run at speeds higher than 40,000 fpm (200 m/s), taking 41 s to remove 1 in 3 (16 cm 3) of material, but is still in the research-and-development (R&D) stage. It also requires high spindle power and high spindle speeds.
In the 1990s, Mastercam significantly expanded its capabilities, introducing 3D design and machining functionalities along with high-speed machining options to cater to the increasing demand for precision in manufacturing.
Milling is the process of machining using rotary cutters to remove material [1] by advancing a cutter into a workpiece. This may be done by varying directions [2] on one or several axes, cutter head speed, and pressure. [3]
High speed steel is commonly used when a special tool shape is needed, not usually used for high production processes. Ceramics inserts are typically used in high speed machining with high production.
