9. Formed Cutter. The formed cutters have irregular profiles on the cutting edges in order to generate an irregular outline of the work. The different types of standard formed cutters are described below. Convex Milling Cutter. The convex milling cutters have teeth curved outwards on the circumferential surface to form the contour of a semicircle.
Angle milling cutters have circumferential teeth and its cutting edges lie on a conical surface (Refer Fig. 16.43). (e) Concave Milling Cutter: This is a formed cutter which is shaped to mill a convex surface of circular contour equal to half a circle or less (Refer Fig. 16.44). (f) …
Milling cutters usually have teeth cut on the periphery and/or on the end of a disk or cylinder. Alternatively, 'inserted-tooth' cutters with replaceable teeth may be used. In horizontal milling 'up-cutting' is the usual practice, but 'down-cutting' may be used. The types of cutter are listed in the following table.
Formed Milling Cutter Irregular profiles are formed on the cutting edges of the formed cutters, which can lead to irregular outlines on the work. Different types of standard formed cutters are as follows Convex milling cutter Concave milling cutter Corner milling cutter Gear cutter Thread milling cutter End Mill Cutter
Machining of a flat surface at an angle, other than a right angle, to the axis of revolving cutter. 9. Form milling is the process of machining special contours composed of curves and straight lines, or entirely of curves, at a single cut. This is done with formed milling cutters, shaped to the contour to be cut. 10.
The form cutters can be made from alloy steel, solid carbide, brazed carbide, and HSS. The common types of form milling cutters include convex, concave, and corner rounding milling cutters. Form milling cutter can also come in straight gash, spiral gash, serration form, special form relieved, simple keyway bores, and complex hubs & shanks.

CNC machining is a highly utilised subtractive manufacturing technology. Computer numerical control systems offer less need for manpower and higher levels of automation. One of these automated fabrication methods is CNC milling.It is a process where rotary cutters remove material, which makes it the opposite of CNC turning.. The milling centres do not just perform …
The cutters that can be used for milling operations are highly diverse, thus allowing for the formation of a variety of features. While these cutters differ greatly in diameter, length, and by the shape of the cut they will form, they also differ based upon their orientation, whether they will be used horizontally or vertically.
with formed cutters or generating the shape with a rack cutter, a shaping cutter or a hob cutter. ROUGHING PROCESSES FORM MILLING BY DISC CUTTER The disc cutter shape conforms to the gear tooth space. Each gear needs separate cutter. However, with 8 to 10 Std. cutters, gears from 12 to 120 teeth can be cut with fair accuracy.
