3. Ultrasonic machining - Wikipedia

   en.wikipedia.org/wiki/Ultrasonic_machining

   The abrasive grains in the slurry now act as a free cutting tool as they strike the workpiece thousands of times per second. [3] An electronic oscillator in the control unit produces an alternating current oscillating at a high frequency, usually between 18 and 40 kHz in the ultrasonic range. The transducer converts the oscillating current to a ...

4. Reciprocating saw - Wikipedia

   en.wikipedia.org/wiki/Reciprocating_saw

   A reciprocating saw is a type of handheld, small, machine-powered saw, in which the cutting action is achieved through a push-and-pull ("reciprocating") or back-and-forth motion of the blade. The original trade name, Sawzall, is often used in the United States, where Milwaukee Electric Tool first produced a tool of this type in 1951. [1] [2]

   A nibbler, or nibblers, [1] is a tool for cutting sheet metal with minimal distortion. They may be used for nibbling. One type operates much like a punch and die, with a blade that moves in a linear fashion against a fixed die, removing small bits of metal and leaving a kerf approximately 6 mm (0.24 in) wide. Another type operates similar to ...

Blanking is the operation of cutting flat shapes from sheet metal. The outer area of metal remaining after a blanking operation is generally discarded as waste. Size of blank or product is the ...

7. Cutting tool (machining) - Wikipedia

   en.wikipedia.org/wiki/Cutting_tool_(machining)

   Cutting tool materials must be harder than the material which is to be cut, and the tool must be able to withstand the heat and force generated in the metal-cutting process. Also, the tool must have a specific geometry, with clearance angles designed so that the cutting edge can contact the workpiece without the rest of the tool dragging on the ...
