The inferior finish found on the machined surface of a workpiece may be caused by incorrect clamping, a dull tool, or inappropriate presentation of a device. Frequently, this poor surface finish, known as chatter, is evident by an undulating or regular finish of waves on the machined surfaces of the workpiece.
Re-Machined features mostly specially recorded tracks from former Deep Purple Mk III member Glenn Hughes with Chad Smith of Red Hot Chili Peppers, Iron Maiden, Metallica, Chickenfoot, Steve Vai, Black Label Society, Carlos Santana and Papa Roach vocalist Jacoby Shaddix - their version of "Smoke on the Water" has previously been released on the Santana album Guitar Heaven, Jimmy Barnes & Joe ...
The English word machine comes through Middle French from Latin machina, [2] which in turn derives from the Greek (Doric μαχανά makhana, Ionic μηχανή mekhane 'contrivance, machine, engine', [3] a derivation from μῆχος mekhos 'means, expedient, remedy' [4]). [5]
In this approach, the tool travels along a gradually evolving spiral path. The spiral starts at the center of the pocket to be machined and the tool gradually moves towards the pocket boundary. The direction of the tool path changes progressively and local acceleration and deceleration of the tool are minimized. This reduces tool wear. [17]
For instance, some motors use a precisely machined boss on the front face to locate it on the mating part. Like a process on a bone, bosses on castings can provide attachment points or bearing surfaces .
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.
The process of feature replication allows the flatness and squareness of a milling machine cross slide assembly, or the roundness, lack of taper, and squareness of the two axes of a lathe machine to be transferred to a machined work piece with accuracy and precision better than a thousandth of an inch, not as fine as millionths of an inch.
The material being machined (steel, brass, tool steel, plastic, wood) (see table below) The material the cutter is made from (High-Carbon Steel, high-speed steel (HSS), Carbide, Ceramics, and Diamond tools) [5] The economical life of the cutter (the cost to regrind or purchase new, compared to the quantity of parts produced)
