The space provided by this clearance keeps the insert from rubbing against the part. If the insert does have a 0-degree clearance angle (N), chances are it is being used in a roughing operation. The different clearances are:

To help insert recognition, the American National Standards Institute (ANSI) developed B212.4-2002 to allow machinists, purchasing departments, and tooling sellers to quickly and easily describe the shape, dimensions, and important parameters of turning inserts.

CNC machines are used for continuous and accurate job production. So to keep this a continuous process some sophisticated tooling is used like tools with the Inserts. The machining with…

The fifth position in ANSI’s designation is either a one-digit or a two-digit number that shows the I.C. size (in eighths of an inch) for round, square, triangle, trigonal, pentagonal, hexagonal, octagonal, and rhombic inserts. If it’s a one-digit number, the eighths of an inch make a whole number.

The eighth, ninth, and 10th positions in ANSI’s guide are optional and represent the cutting edge condition (aka edge prep, such as sharp, rounded, or chamfered); cutting direction (left, right, or neutral); and information on the insert’s chipformer (FP -- finishing sharp, UN -- universal medium, and HP – high positive).

For parallelogram- and rectangular-shaped inserts, width and length dimensions are used instead of the I.C. In these cases, a two-digit number designates the insert’s size. The first digit is how wide the insert is (in eighths of an inch) and the second digit is how long the insert is (in quarters of an inch).

Today I am going to explain the threading insert nomenclature which are used for threading on cnc machines. Of course there are plenty of different types of threading inserts and the…

Insert thickness is measured from the bottom of the insert to the top of the cutting edge. It also is shown as a one- or two-digit number (indicating the number sixteenths of an inch). Much like the size designation, it is a one-digit number when it describes a whole number. In our example, the insert’s thickness, 3, means that it is 3/16 in. thick.

Inserts can be designed with or without holes; have cylindrical, single-countersink, or double-countersink holes; and come with multiple chipformer styles. If the insert has a designation of X in this location, it has a special design.

The fourth letter of general turning insert nomenclature tells us about the turning insert hole shape and chip breaker type.

A large nose radius can use higher feed rates, larger DOCs, and handle more radial pressure. A small nose radius takes only small cutting depths, has a weaker cutting edge, and can handle only a small amount of vibration. Our example insert has a radius of 2, meaning it has a nose radius of 1/32 in.

General turning inserts come in variety of shapes and sizes. One thing is important to remember and understand is that every turning insert has a nomenclature associated with it. These general turning inserts nomenclature tells us lot about these general turning inserts.The turning inserts nomenclature is a list of some letters and numbers, but lot more data is hidden inside them.

The first place shows the shape of the insert. There are 17 standard indexable insert shapes, and each is given a capital letter. In our example, C indicates that the insert is a rhombic-shaped insert of 80 degrees.

The fourth place in an insert’s designation is another capital letter. This one helps describe more of the insert’s design features, such as its fixing holes, countersinks, and any chipformer features. There are 14 standard types (A, B, C, D, G, J, M, N, Q, R, T, U, W, X).

The success or failure of a turning job often depends on decisions made early in the process -- before the cutting even begins -- about a small piece of carbide, cermet, ceramic, or diamond.

Whether the application calls for rough turning, medium turning, or finish turning, the decision on what technology to use should come well before the material is loaded onto the machine or into the bar feeder.

These are the turning insert tolerances in different insert sizes, like the tolerance in turning insert length, height etc. I personally think that they are not of any use for a cnc machinist, because theses tolerances are minor.

There are 14 tolerance classes, the third place, that show how each insert indexes. Each class is denoted by a capital letter. Letters for tolerances are A, B, C, D, E, F, G, H, J, K, L, M, U, and N, which describe the size of the cornerpoint, thickness, and the inscribed circle (I.C.) of the insert. An I.C. is the largest circle that can be drawn inside the given shape.

Single-point cutting tools remove workpiece material by using one of the insert’s cutting edges. But how do you differentiate one insert from another? It starts by understanding their designation.

The most popular turning insert in the industry is the 80 degree diamond (CNMG insert). Known for its balance of versatility and edge strength it is usually the first choice…

Also known as the clearance, the second place shows the angle between the flank and top surface of the insert. Each relief angle is denoted by a capital letter. In our example, the insert has a 0-degree relief angle.

These measurements and tolerances can get tricky and change based on the insert's shape, so it’s a good idea to consult the literature that accompanies your tooling purchase to get this right.

Insert choice requires taking into consideration a whole host of variables, including an insert’s size, shape, and overall design features. In most cases, the tool is held in a fixed position in a tool body and the workpiece rotates in the lathe’s turning axis.

Our example has a G in this place. This indicates that the insert has a cylindrical hole and has a double-sided chipformer.

Turning on a lathe is an operation in which a stationary single-point cutting tool meets a rotating workpiece to produce axially symmetrical shapes. Sounds pretty easy, right? Well, it typically is, if the correct cutting parameters and inserts are chosen for the job.

Some inserts, like round ones (R), have high edge strength, while some rhombic-shaped inserts (D and V) have a sharp point, which is good for finishing operations. Trigonal inserts (W) often are used for rough machining because of their larger point angle. Each has its place. The shape of the insert also determines how many separate edges can be indexed to as each wears out. The common insert shapes are:

For turning inserts, it comes in the form of a 10-place string of numbers and letters, (the first seven are required and the last three are optional), with each describing a portion of the tool.

Other than shape, an insert’s size is one of the variables that is easily noticed. In our example, the 4 indicates that the insert’s size is 1/2 in.

To do this it’s important to have at least some understanding of the American National Standards Institute (ANSI) turning insert designations. ANSI developed this system of numbers and letters (B212.4-2002) to allow machinists, purchasing departments, and tooling sellers to quickly and easily describe the shape, dimensions, and important parameters of turning inserts. It essentially gets everyone on the same page.
