This gradual increase in thrust has advantages for the sharp-edged tooth. This type of milling, the cutter has the tendency to pull away the workpiece, so it is also called up milling. The cutting at starting very light so that teeth slide across the surface. The sliding and biting behavior cause poor surface finish.

So, due to this opposite motion, the width of the cutting chips gradually increases from minimum to maximum. There is massive friction between the cutter and workpiece which results in generating a large amount of heat. Up Milling Advantages: This is a safe operation because It has no tendency to drag the workpiece into the cutter.
Cutting forces tend to push the cutter and workpiece away from each other and radial forces will tend to lift the workpiece from the table. Up milling may be advantageous when large variations in working allowance occur.
A CNC milling machine features a table that automatically moves (or rotates) the workpiece on different planes so the cutting tool can work on it. Unlike manual lathes, a CNC milling machine operates by converting a 3D CAD model into a set of computer instructions, which is then used to dictate the tooling's actions and movements automatically.

In up milling (conventional milling), the feed direction of the cutting tool is opposite to its rotation. The chip thickness starts at zero and increases toward the end of the cut. The cutting edge has to be forced into the cut, creating a rubbing or burnishing effect due to friction, high temperatures and, often times, contact with a work ...
