The milling process – definitions Cutting speed,v c Indicates the surface speed at which the cutting edge machines the workpiece. Effective or true cutting speed, v e Indicates the surface speed at the effective diameter (DC ap).This value is necessary for determining the true cutting data at the actual depth of cut (a p).This is a particularly important value when using round insert cutters ...
This paper presents an improved cutting force model for circular end milling process based on the typical linear milling force model. The curvature effects of tool path on chip thickness as well as entry and exit angles are analyzed, and the cutting force model of linear milling process is then corrected to fit circular end milling processes.

A model of a vertical milling machine feed drive control system is used to analyze cutting force measurements from the drive motors. The current and voltage limits in the amplifier, and the friction in the feed drive assembly are included in the analysis. The viability of using armature current as a cutting force measurement sensor is discussed.
Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a work piece. This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations.
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.
