Oct 21, 2009· Introduction: Milling is the cutting operation that removes metal by feeding the work against a rotating, cutter having single or multiple cutting edges. Flat or curved surfaces of many shapes can be machined by milling with good finish and accuracy. A milling machine may also be used for drilling, slotting, making a circular profile and gear cutting by having suitable attachments.
Mar 04, 2016· Today we will discuss about difference between up milling and down milling. The milling is a machining process in which, a rotary cutter i used to remove the material from work piece in the direction perpendicular t the axis of rotation. The milling process is done by the machine, which hold bot the tool and work piece in jig and fixture, known as milling machine.
Ultrasonic machining is precise enough to be used in the creation of microelectromechanical system components such as micro-structured glass wafers. In addition to small-scale components, ultrasonic vibration machining is used for structural components because of the required precision and surface quality provided by the method.
