Plain milling cutters that are more than 3/4 inch in width are usually made with spiral or helical teeth. A plain spiral-tooth milling cutter produces a better and smoother finish and requires less power to operate. A plain helical-tooth milling cutter is especially desirable when milling an uneven surface or one with holes in it. Types of Teeth
Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. 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.

Jan 01, 2011· Milling Parameters. Programmed milling parameters include axial DOC (ap), feed per tooth (fz), cutting speed (VC) and radial WOC (ae). Axial DOC depends on the indexable-insert geometries, carbide grades and workpiece hardness. When roughing, the axial DOC is about one-half of the height of the insert.
Milling Machine A mill uses rotary cutters to shave, cut or slice sections off of a work piece. CNC technology enables far greater precision in milling than when the operation is performed manually. The CNC milling machine can be programmed to vary in depth, angle and direction of cut.

The basic properties of the milling bodies are their mass and size, ware rate, influence on the particle breakage rate and energy efficiency of the grinding process [15, 18, 22, 28]. A comparison between ball mils and cylpebs is made in [ 42].
Trochoid Milling NC Macros. You can define transition paths in your machining operations by means of NC Macros. These transition paths are useful for providing approach, retract and linking motion in the tool path. An Approach macro is used to approach the operation start point. A Retract macro is used to retract from the operation end point.
Select the Macros tab page to specify the operation's transition paths (approach and retract motion, for example). The general procedure for this is described in Define Macros of an Axial Machining Operation. 10. Select Predefined Helix in Macro tab to give helix approach macro in case of Circular milling operation.
