They're 3D parts to be sure–we live in a 3D world after all. But, cutting movement, with the exception of holes, happens mostly in X and Y, with a constant Z value. The walls of Prismatic Parts are vertical unless tapered cutters were used. And curves are strictly in X and Y, so no convex or concave curves happen on the face of the part.
When woodworking plans call for cutting curves in thick stock, typically the tool of choice is the band saw. Band saws can be easily adjusted to accommodate most thicknesses of stock, and the blade stays straight throughout the cut (a challenge when cutting thick stock with some other tools).

End mills can work themselves out of a split collet if the cut is too heavy or when the cutter dulls. Describe two methods of cutting angular surfaces in a vertical milling machine. Angular cuts can be made by tilting the work piece or by tilting the work head.
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.

10.04.2010 · I've used circular interpolation to cut arcs on milling machnes ever since I learned it was possible in 1966. You have to calculate a tool path and that requires a little trigonometry. The tool path is nothing more than the radius (arc) you wish to cut plus (or minus) the cutter radius.
Milling cutters come in several shapes and many sizes. There is also a choice of coatings, as well as rake angle and number of cutting surfaces.. Shape: Several standard shapes of milling cutter are used in industry today, which are explained in more detail below. Flutes / teeth: The flutes of the milling bit are the deep helical grooves running up the cutter, while the sharp blade along the ...
Placing the workpiece eccentrically a set distance from the center permits more complex curves to be cut. As with other setups on a vertical mill, the milling operation can be either drilling a series of concentric, and possibly equidistant holes, or face or end milling either circular or .
In end milling, the cutter generally rotates on an axis vertical to the workpiece. Cutting teeth are located on both the end face of the cutter and the periphery of the cutter body. A ball nose end mill, also known as a spherical end mill or ball end mill, has a semisphere at the tool end.
Vertical turret mills have a stationary spindle and the table is moved both perpendicular and parallel to the spindle axis to execute cutting. They often have a quill that allows the milling cutter to be raised and lowered in a manner quite like a drill press.
