Choosing flat end mill vs. a ball end mill will determine the characteristics of the tooling marks (or lack thereof) on your model. most jobs will benefit from strategic use of multiple size and shape tools for milling different features. end mills are often used for roughing and 2d cutting and v-bit and ball nose cutters are often used for .
Axial depth of cut = ad. for tool diameters 1/8 and under: ad = dia. of tool x 0.25 to 0.05. for diameters above 1/8 ad = dia. x .05 to 1.5. sfm and feed. for ad between 0.25 to 0.5 of tool dia. sfm = 0.8 lowest range value. feed at suggested value. for ad equal and above tool dia. sfm = 0.8 x highest speed range.
it is possible to use flat end mill on the outside scallop but this is not right, scallop is meant to be used with ball or bull nose end mill. in order to achieve smooth surface finish, you'd have to take something like .0005 step over cuts, just not the way things are done.

Flat end mill is the end mill with flat/square end. it is a general end type for rough milling,more economic compared with ball end mill and corner radius end mill, but it is not suitable for machining in speed as high as other two type end mills because too high rotation and feed rate may cause sharp corner blade to break.
Ball end mills. ball end mills are used for drilling shallow holes, slotting a channel where a flat bottom is not required or most commonly used to produce multi-dimensional contours in molds or dies. the design of ball end mills forms a hemispherical cutting action identical to the diameter of the tool. because of the shapes required in these .
In 304 stainless steel, that means a 0.031 in. (0.8mm) end mill, which leaves a corner radius of 0.016 in. (0.4mm). that's pretty sharp, but the depth is limited. the length of most steel-cutting end mills in this size range maxes out at five times the cutter diameter, barely deep enough to fit your favorite center fielders.

End mills ball nose end mills stub length. stub length ball nose end mills. these carbide ball end mills have a stub flute length (1.5xd), two, three, or four cutting edges, and a center cutting full radius or ball on the end. they are available in general purpose geometries and high performace designs.
End mill end clearance • dish angle –angle between end of cutting edge and perpendicular to the cutter axis –dish ensures a flat surface is produced • gash (notch) –secondary cuts to provide chip space at corners and ends –forming the end cutting edge when feeding axially • gash angle –relief angle of the gash feature.
Ball end mills, also known as ball nose end mills, are used for milling contoured surfaces, slotting and pocketing. a ball end mill is constructed of a round cutting edge and used in the machining of dies and molds. roughing end mills, also known as hog mills, are used to quickly remove large amounts of material during heavier operations.
router bits are mainly used by woodworkers for joint making, to shape wood edges, and to engrave various designs by making depressions. like an end mill, the router bit has many flutes and it comes in straight, spiral, and diamond patterns. they are available with common cut angles of 7 , 15 , 22 , 25 , 45 , 60 , and 90 .
the brand-new ball-nosed version of the harvi i te end mill series is just as versatile as the square-end version. designed for highly productive 3d roughing and finishing operations, it features a “rippled relief” in the ball nose section that provides improved coolant flow into the cutting zone and disperses heat.
ball-nose end mills. ball-nose end mills have a dome-shaped tip. these excel at high-detail contours like relief artwork or mold and die making, but have what is known as scalloping. since the tip of the end mill is round, having a perfectly flat surface is a challenging feat and will take many more passes than a simple .

a ball end mill is not the same as a corner radius/bull nose end mill. the ball has a radius with it's center point at the center of the end mill, so the radius is always 1/2 of the diameter. i've also noticed that bull nose end mills seem more rugged than the basic flat end mill, since it seems that every time i trash an end mill it's .
