A Brief Explanation of CNC Machines and How They Work

CNC – Computer Numerical Control – Taking digitized data, a computer and CAM program is used to control, automate, and monitor the movements of a machine. The machine can be a milling machine, lathe, router, welder, grinder, laser or waterjet cutter, sheet metal stamping machine, robot, or many other types of machines.

Milling Machine: Methods of Milling. Milling Processes

28-06-2009Milling is an important process of manufacturing technology and basically it refers to the removal of metal from the work piece using a tool which has several cutting points and is rotating about its axis. Thus each cutting point removes a little bit of the metal but since there are multiple such points and the tool is rotating at a fast speed, the overall removal is quite brisk.

Ball Mill: Operating principles, components, Uses

05-07-2020Several types of ball mills exist. They differ to an extent in their operating principle. They also differ in their maximum capacity of the milling vessel, ranging from 0.010 liters for planetary ball mills, mixer mills, or vibration ball mills to several 100 liters for horizontal rolling ball mills.

Milling Process, Defects, Equipment

End milling - An end mill makes either peripheral or slot cuts, determined by the step-over distance, across the workpiece in order to machine a specified feature, such as a profile, slot, pocket, or even a complex surface contour.The depth of the feature may be machined in a single pass or may be reached by machining at a smaller axial depth of cut and making multiple passes.

Principle and Working of MILLING MACHINE

21-10-2009Introduction: 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.

Balling Effect

Balling phenomena can also be alleviated by avoiding the completely molten state [38]. Another method to mitigate the balling effect is the introduction of a tiny amount of deoxidants such as boric acid (H 3 BO 3) and potassium tetrafluoroborate (KBF 4), in the powder and thus, very smooth surface with no case of balling can be achieved [60].

In many respects, it is the outlook of Scottish philosopher David Hume (1711-1776) and his writings from the mid-18th century. But it received both its name and its clearest statement in the writings of English philosophers Jeremy Bentham (1748-1832) and John Stuart Mill (1806-1873).
