	Sec. 6 - Introduction
		Machinability is not an intrinsic property of a material, but rather the result of complex interactions between the workpiece and various cutting devices operated at different rates under different lubricating conditions.
		Machining Handbooks do not present an unambiguous indication of the improved machinability of Ductile Iron, and it is instructive to use practical examples whenever possible.
		Coining is a specialized operation that can be used to both deform a Ductile Iron casting to produce its final shape, and shear off ingates, feeder necks and parting line "flash".

		After machining, the electrode is inspected and used to EDM the entire configuration in a single set up.
		The table of the machine where the graphite blank is mounted, orbits slightly in an X & Y motion, while the platen with the stone attached, cycles up and down under hydraulic power.
		Machining copper can sometimes be difficult, since it has a tendency to drag on the cutter, saw blade, and grinding wheel, especially in the hands of an inexperienced machinist.

	How air forming works
		Unlike bottom bending or coining, which reproduce the radius of the punch tip, air forming creates the inside radius as a percentage of the V-die opening, regardless of the punch radius.
		Coining also requires that the punch tip be sharp (less than 63 percent of the material thickness) to produce a 90-degree bend - the sharper the better.
		Coining also works only with a sharp punch, rarely with a punch carrying a radius greater than 63 percent of the material thickness.

	Coining (machining) - Wikipedia, the free encyclopedia
		A beneficial feature is that in some materials, such as phosphor bronze, the plastic flow breaks up the surface grains, work hardening the surface, while the material deeper in the part retains its strength, toughness, ductility and flexibility.
		Coining sometimes uses several dies to produce near-net shapes.
		Mints use coining to produce money (coins), medals, police and fire fighter's badges, precision-energy springs and precision parts with small or polished surface features.

		Additional machining to the bottom interior area of the block accommodates the installation of the crankshaft bearings (known as the "main" bearings), the crankshaft, the front and rear crankshaft oil seals, and the counterweight.
		The precision machining processes entailed rough-grinding the crankshaft, drilling holes in both the flange and the end trunnion, and milling the keyways so that the fly wheel and gear wheel could be fastened to a finished crankshaft.
		After the end parts were machine finished, each crankshaft was dynamically balanced and the differing distribution of the mass of the shaft was equalized; all bearing surfaces were lapped and polished to improve surface finish; and the crankshaft was washed and inspected.

	Design tips for sheet metal: Bend relief, small holes, hole distortion near bends, and minimum flange widths
		The article discusses making small holes and when to use a punch or laser cutter, inside radius measurements and how they differ depending on whether you are coining or air bending on a press brake, and adding bend relief to prevent tearing material.
		Coining uses enough tooling pressure to cause the workpiece material to flow into the final configuration.
		With air bending, the inside radius is controlled largely by the V-die opening; the "normal" range for the radius is one to two times the material thickness.

	ServoCon ALPHA: Metal Forming
		Machines which perform Solid metal and molten metal processes such as casting, forging, stamping and machining.
		Coining is a compressive metal flowing action or a closed-die squeezing operation in which all surfaces of a work piece are confined or restrained, resulting in a well-defined imprint of the die on the work.
		Machining can be used to make a component from stock material but more often it is used as a secondary process to impart a shape or a level of precision to a manufactured component that cannot be achieved otherwise.

	(Molding) Metal Injection Molding: Enhanced Processes Offer High-Precision Results (MDDI archive, Nov 00)
		Unfortunately, none of these processes alone is able to yield very tight tolerance control, and secondary machining or coining is frequently required.
		Transducers in the machine's end-cap or nozzle use direct-melt pressure to control the packing and metering stages of the molding process.
		The machines automatically correct for viscosity changes by comparing the numeric integrals of the melt-pressure curve and numeric differentials of the cavity-pressure curve in the injection phase, and by correcting packing pressures accordingly for the same shot.
