Chip Load (or Maximum Chip Thickness) is one of the most important parameters for achieving a stable and productive milling process. Radial chip thinning occurs when the width of cut is less than 50% of the cutter diameter. Examining from a top view, when feeding an endmill at 50% radial engagement (Figure A-A), the chip […]

These end mills have a serrated cutting edge that generates significantly smaller chips than a standard end mill cutting edge. This allows for smoother machining and a more efficient metal removal process.

To aid with even more chip evacuation and leave a better finish on the part, a small notch profile is ground along the cutting edge on a helical pattern up the flutes at a half times the diameter spread breaks down the long chips into even smaller manageable chips and with the helical ground pattern […]

To aid chip evacuation, a “V’ type notched profile is ground along the cutting edge that break down long chips into smaller, more manageable pieces.

HEM has evolved from a philosophy that takes advantage of the maximum amount of work that a tool can perform. Considerations for chip thinning and feed rate adjustment are used so that each cutting edge of a tool takes a consistent chip thickness with each rotation, even at varying radial depths of cut and while […]

HSM encompasses a technique that results in higher production rates while using a much different approach to depth of cut and speeds and feeds.HSM uses constant values for the key parameters. A very high spindle speed paired with much lighter axial depths of cut results in a much higher allowable feed rates.

Trochoidal milling is a method of machining used to create a slot wider than the cutting tool’s cutting diameter. This is accomplished using a series of circular cuts known as a trochoidal tool path. A form of High Efficiency Milling (HEM), trochoidal milling leverages high speeds while maintaining a low radial depth of cut (RDOC) […]
