CNC Part Program for Milling Process ~Dinesh Krishnaa S 22MI31,PSGCT.

Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece . It is one of the most commonly used processes for machining custom parts to precise tolerances.

Section 1 – End Milling.

End Milling. End milling involves using a specific cutting tool, an end mill, to make axial cuts into a workpiece. It is an aspect of milling operation used for special applications such as producing die cavities, profiles , slots, contours, shoulders, and other milling parts.

Tools Required. Milling cutters are cutting tools that are typically used in milling machines or machining centers to perform milling operations They remove material by moving it within the machine or directly from the cutting die.
